The newly defined Agrilus gratiosus species-group comprising ten species from the Oriental region is revised. A key to species is provided and complemented with illustrations of habitus, genitalia and type specimens. The following seven new species are described: Agrilus cultus sp. nov. (Laos); A. oudomxai sp. nov. (Laos); A. pergratus sp. nov. (Malaysia); A. pluridens sp. nov. (Laos, Thailand); A. pubinotus sp. nov. (Indonesia: Sumba Island); A. siberuticola sp. nov. (Indonesia: Siberut Island) and A. signipes sp. nov. (Vietnam). Agrilus makiharai Tôyama, 1987 is considered conspecific with A. bacchus Kerremans, 1913 and therefore the name makiharai syn. nov. is a junior subjective synonym of the name bacchus.
The genus Systaria Simon 1897 is reviewed in Southeast Asia and eight new species are described: S. lannops spec. nov. from Thailand (female), S. longinqua spec. nov. (male, female) and S. luangprabang spec. nov. (female) from Laos, S. procera spec. nov. (male, female) and S. bregibec spec. nov. (male) from Cambodia, S. bifidops spec. nov. from Malaysia (male), S. panay spec. nov. (female) and S. princesa spec. nov. (male, female) from Philippines. S. elberti (Strand 1913) is illustrated and partly re-described. Informal groups of species are proposed for the first time. Distribution ranges and habitat preferences are mapped.
Halone Walker (1854) is one of the small genera within the tribe Lithosiini of subfamily Arctiinae (Erebidae). It was established for its type species, Halone sobria Walker, 1854, from Australia. The genus Halone is distributed in Southeast Asia (total 14 spp.: 3 spp. from India; 1 sp. from Thailand; 9 spp. from Malay Peninsula; 1 sp. from Papua New Guinea) to Australia (total 14 spp.), with 28 species described by several authors in various genera: Halone sobria Walker (1854), Setina sinuata Wallengren (1860), Pitane sejuncta Felder Rogenhofer (1875), Mosoda consolatrix Rosenstock (1885), Mosoda servilis and M. ophiodes Meyrick (1886), Sorocostia interspersa Lucas (1890), Halone coryphoea and H. ebaea Hampson (1914), Eurypepla pteridaula Turner (1922), Halone epiopsis and H. prosenes Turner (1940), Psapharacis camptopleura and Scaphidriotis xylogramma Turner (1899) from Australia; Halone furcifascia Hampson (1914) from Papua New Guinea; Halone ariadna, H. bifornica, H. dissimulata, H. oblimarea, H. pillea, H. iuguma, H. marketae, H. solitus and H. viktorai Bucsek (2012; 2014) from Malay Peninsula; Halone straturata Černý (2009) from Thailand; Aemene diffusifascia Swinhoe (1896), Aemene flavescens Hampson (1898), and Halone flavinigra Hampson (1907) from India. The genus is cataloged in Poole (1989) and Edwards (1996).
The available information about the cleptoparasitic bees of the genus Sphecodes in Southeast Asia is summarized. Thirty-one species are currently known from this area. Four new species are described: Sphecodes discoverlifei Astafurova & Proshchalykin, sp. nov. (Laos), S. engeli Astafurova & Proshchalykin, sp. nov. (Laos, Vietnam), S. ilyadadaria Astafurova, sp. nov. (Indonesia), and S. pseudoredivivus Astafurova & Proshchalykin, sp. nov. (Laos). Nine species are newly recorded from South East Asia: S. chaprensis Blüthgen, 1927 (Laos), S. howardi Cockerell, 1922 (Malaysia, Myanmar, Thailand), S. kershawi Perkins, 1921 (Indonesia, Malaysia, Myanmar, Thailand), S. laticeps Meyer, 1920 (Thailand, Vietnam), S. montanus Smith, 1879 (Laos), S. sauteri Meyer, 1925 (Laos), S. sikkimensis Blüthgen, 1927 (Laos, Myanmar), S. simlaensis Blüthgen, 1924 (Laos), and S. turneri Cockerell, 1916 (Laos). Based on type specimens, new synonymies have been proposed for Sphecodes kershawi Perkins, 1921 = S. javanensis Blüthgen, 1927, syn. nov.; S. simlaensis Blüthgen, 1924 = S. simlaellus Blüthgen, 1927, syn. nov.; S. laticeps Meyer, 1920 = S. biroi mariae Cockerell, 1930, syn. nov. Lectotypes are designated for Sphecodes biroi Friese, 1909, S. simlaellus Blüthgen, 1927, and S. laticeps Meyer, 1920. The female of Sphecodes sauteri Meyer, 1925, and the male of S. turneri Cockerell, 1916 are described for the first time.
A new species of the rarely collected ant genus Platythyrea Roger, 1863 closely related to Platythyrea clypeata Forel, 1911 is described and illustrated based on the worker caste under the name Platythyrea janyaisp. n. This species is distributed in southern Thailand and western Malaysia, while P. clypeata is distributed in Sri Lanka, Vietnam, Laos, and Thailand in the areas north of the Isthmus of Kra. Platythyrea clypeata is newly recorded from Thailand from dead wood on the forest floor. The type series of P. janyai was also collected from rotten wood on the forest floor.
Six Oriental species of Evaza Walker, 1856 were described by J.C.H. de Meijere in the period between 1911 and 1924. The type specimens are now deposited in the Museum Naturalis (Leiden). All species were redescribed, photographed and their diagnostic characters were defined. Male terminalia of five species with known males were illustrated in detail. The revised species were compared with recently described new species from Oriental China. Additional material belonging to the revised species was recorded for the first time from the following countries: Evaza demeijerei Brunetti, 1923 (= E. pallipes de Meijere, 1916a) and E. discolor de Meijere, 1916a were found in Malaysia, E. javanensis de Meijere 1911 in Singapore, E. kerteszi de Meijere, 1914 in Laos and Malaysia and E. maculifera de Meijere, 1914 in Malaysia, Philippines, Thailand and Vietnam.
Malaria vector surveys were carried out in 8 provinces in Lao PDR in 1999. The surveys were conducted in 4 provinces - Savannakhet, Champasak, Luang Perbang and Sayaboury in May and in another 4 provinces - Bolikhamsay, Sarvan, Sekong and Vientiane in December 1999. Bare leg collection were carried out indoors and outdoors from 6 pm to 5 am. All anopheline mosquitos were identified, dissected and the gut, gland and ovaries were examined. A total of 438 Anopheles mosquitos belonging to 19 species were obtained. Of these only 3 species were found to be infected with oocysts - An. maculatus, An. dirus and An. minimus. All these species were found biting both indoors and outdoors. An. aconitus was the predominant species obtained in the December collection but its vectorial status remains unknown.
In the Lao People's Democratic Republic (Laos), stroke is ranked as the third leading cause of death, with a 9·01% mortality rate. To date, neither the prevalence nor the incidence of stroke has been recorded in Laos. This omission may be attributed to a lack of awareness among Laotians of the signs and symptoms of stroke, incomplete data, or insufficient database recording. The only risk factor for stroke that has been studied extensively is cigarette smoking; studies have found that smokers have twice the risk of stroke. Unfortunately, smoking is increasing among youths, adults, and even healthcare professionals. The Southeast Asia Tobacco Control Alliance stated that 42% of hospitalized stroke patients are smokers. Laos is one of the least developed countries in the world, and the country has only one fully trained neurologist for the growing number of stroke cases. The Laos government should seek help from international bodies, such as the World Health Organization, to monitor and rehabilitate stroke patients and prevent stroke occurrence and recurrence.
Vietnam, Laos, and Cambodia have reported first cases of Zika virus (ZIKV) infection since 2010 (Cambodia) and 2016 (Vietnam and Laos). One case of ZIKV-related microcephaly was recognized among a hundred infected cases in these areas, raising a great concern about the health risk related to this virus infection. At least 5 cases of ZIKV infection among travelers to Vietnam, Laos, and Cambodia were recorded. It is noticeable that ZIKV in these areas can cause birth defects. This work aims to discuss the current epidemics of ZIKV in Vietnam, Laos, and Cambodia and update the infection risk of ZIKV for travelers to these areas.
In 1988, the World Health Assembly resolved to eradicate poliomyelitis globally by 2000. A plan of action for polio eradication in the Western Pacific Region (WPR) by 1995 was adopted in 1990. The plan was based on routine and supplemental vaccination activities with oral poliovirus vaccine (OPV) and acute flaccid paralysis (AFP) surveillance in the eight countries where polio was endemic (Cambodia, China, Laos, Malaysia, Mongolia, Papua New Guinea, Philippines, and Vietnam). Regionwide, the number of reported polio cases decreased from approximately 6000 in 1990 to zero in 1998. This report describes the extensive efforts to eliminate the last chains of poliovirus transmission in the Mekong River area.
Oxytelus species are widespread over all continents except Antarctica. Southeast Asia is one of the biodiversity hotspots in the world. In this paper, we review the Oxytelus species currently known from Southeast Asia. Seven species are described as new to science: O. castaneus sp. nov. (Vietnam), O. finitimus sp. nov. (Laos), O. grandiculus sp. nov. (Malaysia, Indonesia, and Thailand), O. insulanus sp. nov. (Malaysia and Indonesia), O. lompobatangensis sp. nov. and O. poecilopterus sp. nov. (Indonesia), and O. sublividus sp. nov. (Vietnam and Laos). Seven new synonymies are proposed: O. ruptus Fauvel = O. sublucidus Cameron, O. lucens Bernhauer = O. malaisei Scheerpeltz, O. puncticeps Kraatz = O. (Anotylus) micantoides Scheerpeltz, O. subferrugineus Cameron = O. kedirianus Cameron, O. megaceros Fauvel = O. kalisi Bernhauer, O. subincisus Cameron = O. fruhstorferi Cameron, O. antennalis Fauvel = O. cheesmani Bernhauer. Lectotypes are designated for the following names: O. armiger Fauvel, O. bellicosus Fauvel, O. discalis Cameron, O. gigantulus Fauvel, O. ginyuenensis Bernhauer, O. javanus Cameron, O. kalisi Bernhauer, O. kedirianus Cameron, O. lucens Bernhauer, O. lucidulus Cameron, O. mandibularis Cameron, O. megaceros Fauvel, O. nilgiriensis Cameron, O. subferrugineus Cameron, O. subincisus Cameron, O. sublucidus Cameron, O. subsculptus Cameron, O. antennalis Fauvel (New Caledonia, New Guinea and Australia), O. cheesmani Bernhauer (New Hebrides), O. cheesmanianus Cameron (Papua New Guinea), O. hingstoni Cameron (India), and O. tibetanus Bernhauer (China). The species O. (Anotylus) transversipennis Scheerpeltz is transferred to the genus Anotylus. Other than the new species, nine previously known species are redescribed, a key to 30 species and line drawings or color photographs of 42 species are provided. Thus, a total of 30 species are recorded from Southeast Asia.
A phylogenetic tree and median-joining network based on cytochrome b sequence data revealed clades consistent with morphological differences and geographical distribution of Clarias batrachus (Linnaeus, 1758) in Southeast Asia. AMOVA analysis for variation was significant among populations (P<0.05) and was in agreement with morphological differences. Pairwise differences were significant between Java and Brunei/Borneo, Brunei/Borneo and west Malaysia, and Java and west Malaysia samples (P < 0.05). Closest relationships were found between samples from Brunei/Borneo and Java, and between west Malaysia and Laos-Sumatra. Nine haplotypes were unique to geographical regions. The Java species had high haplotype (1.000 ± 0.126) but low nucleotide (0.017) diversities, suggesting a population bottleneck followed by expansion. However, SSD and Hri (P=0.5) did not support demographic expansion. Instead, purifying selection where mutations occur and accumulate at silent sites is a more acceptable explanation.
Southeast Asia is known for its rich linguistic, cultural and biological diversity. While ethnobiology in the west has benefitted greatly from intellectual and methodological advances over the last decades, the status of Southeast Asian ethnobiology is largely unknown. This study aims to provide an analysis of the current status of ethnobiology in Southeast Asia and outlines possibilities for future advancements.
The spider suborder Mesothelae, containing a single extant family Liphistiidae, represents a species-poor and ancient lineage. These are conspicuous spiders that primitively retain a segmented abdomen and appendage-like spinnerets. While their classification history is nearly devoid of phylogenetic hypotheses, we here revise liphistiid genus level taxonomy based on original sampling throughout their Asian range, and on the evidence from a novel molecular phylogeny. By combining morphological and natural history evidence with phylogenetic relationships in the companion paper, we provide strong support for the monophyly of Liphistiidae, and the two subfamilies Liphistiinae and Heptathelinae. While the former only contains Liphistius Schiödte, 1849, a genus distributed in Indonesia (Sumatra), Laos, Malaysia, Myanmar, Thailand, we recognize and diagnose seven heptatheline genera, all but three removed from the synonymy of Heptathela: i) Ganthela Xu & Kuntner, gen. n. with the type species Ganthelayundingensis Xu, sp. n. is known from Fujian and Jiangxi, China; ii) a rediagnosed Heptathela Kishida, 1923 is confined to the Japanese islands (Kyushu and Okinawa); iii) Qiongthela Xu & Kuntner, gen. n. with the type species Qiongthelabaishensis Xu, sp. n. is distributed disjunctly in Hainan, China and Vietnam; iv) Ryuthela Haupt, 1983 is confined to the Ryukyu archipelago (Japan); v) Sinothela Haupt, 2003 inhabits Chinese areas north of Yangtze; vi) Songthela Ono, 2000 inhabits southwest China and northern Vietnam; and vii) Vinathela Ono, 2000 (Abcathela Ono, 2000, syn. n.; Nanthela Haupt, 2003, syn. n.) is known from southeast China and Vietnam.
Electrophoretically-detected allozyme variation is described in strains of Schistosoma japonicum (4 Philippine strains), S. mekongi (Laos), and an undescribed anthropophilic S. japonicum-like schistosome from Peninsular Malaysia. Result, together with those reported previously for 8 other strains (S. japonicum, China, Formosa, Japan, Philippines; S. mekongi, 2 substrains; Malaysian schistosome, 2 strains) permit a composite genetic characterization of 15 strains of Asian schistosomes at 9-18 presumptive loci. The proportion of polymorphic loci (P) and the mean heterozygosity per locus (H) were zero in all strains. Although this was expected for strains that had been in laboratory culture for up to 50 years, we expected to detect variation in strains based on 10-50 recently field-collected infected snails. We expected S. japonicum to be as variable as S. mansoni (P = 0.13 (0-0.33), H = 0.04, 18 loci, 22 strains) as it is believed to reproduce sexually, has an evolutionary history of several million years, inhabits a wide geographic range, coevolved with a genetically variable intermediate snail host, and has a diversity of mammalian hosts. No differences were detected between the 5 S. japonicum strains from Leyte and Luzon (Philippines), between the 3 S. mekongi strains, or between the 3 Malaysian schistosome strains; these groups and the remaining S. japonicum strains representing Mindoro (Philippines), China, Formosa, and Japan each have distinctive multilocus electromorphic patterns. Nei's genetic distances (D) were calculated to estimate interstrain and interspecific divergence. Interstrain genetic distances in S. japonicum averaged greater than 0.3; much higher than those reported previously for S. mansoni (D = 0.06, D(max) = 0.24). S. japonicum (Mindoro) was moderately differentiated from the Leyte-Luzon strains (D = 0.29, 12 loci). Estimates of the S. japonicum China-Philippine distance (D greater than 0.4, 11 loci) are high for conspecific populations and further studies of the still poorly characterized Chinese parasite may reveal that these are, in fact, separate species. S. japonicum is shown to be only distantly related to S. mekongi and the Malaysian schistosome (D greater than 1); the latter is closely related to, but genetically quite distinct from, S. mekongi (D = 0.61 +/- 0.275, 11 loci) and warrants recognition as a new species. The medical significance of the isogenic nature of the Asian schistosome strains and their evolutionary divergence are discussed.
The predominantly tropical ophionine genus Enicospilus Stephens, 1835 is one of the largest genera of Darwin wasps (Hymenoptera, Ichneumonidae), with more than 700 extant species worldwide that are usually crepuscular or nocturnal and are parasitoids of Lepidoptera larvae. In the present study, the Japanese species of Enicospilus are revised using an integrative approach (combined morphology and DNA barcoding). On the basis of 3,110 specimens, 47 Enicospilus species are recognised in Japan, eight of which are new species (E. acutus Shimizu, sp. nov., E. kunigamiensis Shimizu, sp. nov., E. limnophilus Shimizu, sp. nov., E. matsumurai Shimizu, sp. nov., E. pseudopuncticulatus Shimizu, sp. nov., E. sharkeyi Shimizu, sp. nov., E. takakuwai Shimizu, sp. nov., and E. unctus Shimizu, sp. nov.), seven are new records from Japan (E. jilinensis Tang, 1990, E. laqueatus (Enderlein, 1921), E. multidens Chiu, 1954, stat. rev., E. puncticulatus Tang, 1990, E. stenophleps Cushman, 1937, E. vestigator (Smith, 1858), and E. zeugos Chiu, 1954, stat. rev.), 32 had already been recorded in Japan; three (E. biharensis Townes, Townes & Gupta, 1961, E. flavicaput (Morley, 1912), and E. merdarius (Gravenhorst, 1829)) have been erroneously recorded from Japan based on misidentifications, and four names that were previously on the Japanese list are deleted through synonymy. The following taxonomic changes are proposed: E. vacuus Gauld & Mitchell, 1981, syn. nov. (= E. formosensis (Uchida, 1928)); E. multidensstat. rev.; E. striatus Cameron, 1899, syn. nov. = E. lineolatus (Roman, 1913), syn. nov. = E. uniformis Chiu, 1954, syn. nov. = E. flatus Chiu, 1954, syn. nov. = E. gussakovskii Viktorov, 1957, syn. nov. = E. striolatus Townes, Townes & Gupta, 1961, syn. nov. = E. unicornis Rao & Nikam, 1969, syn. nov. = E. unicornis Rao & Nikam, 1970, syn. nov. (= E. pungens (Smith, 1874)); E. iracundus Chiu, 1954, syn. nov. (= E. sakaguchii (Matsumura & Uchida, 1926)); E. sigmatoides Chiu, 1954, syn. nov. (= E. shikokuensis (Uchida, 1928)); E. yamanakai (Uchida, 1930), syn. nov. (= E. shinkanus (Uchida, 1928)); E. ranunculus Chiu, 1954, syn. nov. (= E. yezoensis (Uchida, 1928)); and E. zeugosstat. rev. = E. henrytownesi Chao & Tang, 1991, syn. nov. In addition, the following new regional and country records are also provided: E. flavocephalus (Kirby, 1900), E. puncticulatus, and E. vestigator from the Eastern Palaearctic region, E. laqueatus from the Eastern Palaearctic and Oceanic regions, and E. maruyamanus (Uchida, 1928) from the Oriental region; E. abdominalis (Szépligeti, 1906) from Nepal, E. flavocephalus from Laos, E. formosensis from Laos and Malaysia, E. insinuator (Smith, 1860) from Taiwan, E. maruyamanus from India and Philippines, E. nigronotatus Cameron, 1903, E. riukiuensis (Matsumura & Uchida, 1926), and E. sakaguchii from Indonesia, E. pungens from 14 countries (Australia, Bhutan, Brunei, Indonesia, Laos, Malaysia, Nepal, New Caledonia, Papua New Guinea, Philippines, Solomon Islands, Sri Lanka, Tajikistan, and Taiwan), and E. yezoensis from South Korea. An identification key to all Japanese species of Enicospilus is proposed. Although 47 species are recognised in the present study, approximately 55 species could potentially be found in Japan based on ACE and Chao 1 estimators. The latitudinal diversity gradient of Enicospilus species richness is also tested in the Japanese archipelago based on the constructed robust taxonomic framework and extensive samples. Enicospilus species richness significantly increases towards the south, contrary to the 'anomalous' pattern of some other ichneumonid subfamilies.
In this study, we isolated a virus strain (YN12031) from specimens of Armigeres subalbatus collected in the China-Laos border. BHK-21 cells infected with YN12031 exhibited an evident cytopathic effect (CPE) 32 h post-infection. The virus particles were spherical, 70 nm in diameter, and enveloped; they also featured surface fibers. Molecular genetic analysis revealed that YN12031 was closely related to alpha viruses such as Chikungunya virus and Sindbis virus, and located in the same clade as MM2021, the prototype of Getahvirus (GETV) isolated in Malaysia in 1955. Phylogenetic analysis of the E2 and capsid genes further revealed that YN12031 was located in the same clade as the Russian isolate LEIV/16275/Mag. Analysis of the homology of nucleotides and amino acids in the coding area and E2 gene demonstrated that the YN12031 isolated from the China-Laos border (tropical region) was related closest to the LEIV/16275/Mag isolate obtained in Russia (North frigid zone area) among other isolates studied. These results suggest that GETV can adapt to different geographical environments to propagate and evolve. Thus, strengthening the detection and monitoring of GETV and its related diseases is very crucial.
Aedes-borne virus disease control relies on insecticides to interrupt transmission. Temephos remains a key chemical for control of immature stage Aedes in Thailand and much of Southeast Asia. However, repeated use of insecticides may result in selection for resistance in vector populations, thus compromising operational intervention. Herein, the phenotypic response to temephos by Aedes aegypti (L.) and Aedes albopictus (Skuse) collected in Thailand and surrounding countries is presented. Data from 345 collection sites are included: 283 from literature review (244 sites with Ae. aegypti, 21 with Ae. albopictus, and 18 having both species sampled), plus 62 locations with Ae. aegypti in Thailand conducted between 2014 and 2018. Susceptibility assays followed WHO guidelines using the recommended discriminating dose of temephos (0.012 mg/liter) against late third to early fourth instar Ae. aegypti. Findings revealed 34 locations with susceptible Ae. aegypti, 13 with suspected resistance, and 15 indicating resistance. Published data between 1999 and 2019 in Thailand found Ae. aegypti resistant in 73 of 206 collection sites, whereas 3 locations from 11 sampled with low-level resistant in Ae. albopictus. From surrounding countries conducting temephos assays (Cambodia, Lao PDR, Myanmar, Malaysia, and Singapore), resistance is present in Ae. aegypti and Ae. albopictus from 27 of 56 and 19 of 28 locations, respectively. Routine insecticide susceptibility monitoring should be an operational requirement in vector control programs. Given the wide distribution and apparent increase in temephos-resistance, alternative larvicidal compounds must be considered if chemical control is to remain a viable vector control strategy.
Background Factors and policies which potentially explain the changes in alcohol consumption and related harms from 2010 to 2017 in 11 middle-income countries in the South-East Asian region (Cambodia, Lao PDR, Indonesia, the Philippines, Malaysia, Maldives, Myanmar, Sri Lanka, Thailand, Timor-Leste, and Vietnam) were examined. Methods Using secondary data from UN agencies, we analyzed trends in alcohol consumption, alcohol-attributable deaths and the burden of disease. Results Starting from a level of consumption significantly below the global average-especially among the Muslim-majority countries (Maldives, Indonesia, and Malaysia)-the majority of the countries in this region had markedly increased their alcohol consumption along with the economic development they experienced between 2010 and 2017. In fact, five middle-income countries in this region (Vietnam, Lao PDR, Cambodia, Myanmar, and Timor-Leste) were in the top 12 countries globally based on absolute increases in adult alcohol per capita consumption (APC). The Philippines and Malaysia were the exceptions, as they had reduced their APC over this period. The majority of South-East Asian countries had parallel increasing trends in the age-standardized alcohol-attributable deaths and DALYs since 2010, in contrast to global trends. While all countries put some alcohol control policies in place, there were differences in the number and strength of the policies applied, commensurate with trends in consumption. In particular, three of the countries which were most successful in reducing consumption and harm (Malaysia, Philippines, and Sri Lanka) applied more effective tax methods based on specific taxation alone or in combination with another taxation method, applying higher taxation rates and regularly increasing them over time. Conclusion To achieve the global target and the Sustainable Development Goal in reducing alcohol consumption worldwide, middle-income countries, especially lower-middle-income countries, should employ stricter alcohol control policies, and apply an appropriate excise tax on alcohol products with regular increases to reflect inflation.
This study was conducted to determine the morphology, prevalence and mean intensity of monogeneans on gill filaments of striped catfish Pangasianodon hypophthalmus (Pangasiidae).P. hypophthalmus are important economic fish in Southeast Asia region and predominantly produced in Asian countries such as Malaysia, Bangladesh, Indonesia, Vietnam, Laos, China and Cambodia through aquaculture. Thirty fish were sampled from an earthen pond located in Kuala Besut, Terengganu, in the period from January to February, 2018. The monogenean parasites were removed from the gill filaments and counted. For the morphological study, the extracted monogeneanswere mounted on a slide by using drop of ammonium picrate-glycerin (APG) and then were observed under the Compound Advanced Research Microscope. The drawing was done with the aid of lucida camera attached to compound microscope. The monogenean parasite was identified as Thaparocleidussp based on the characteristics of the morphology and morphometrics of the parasite, which did not differ significantly from the previous descriptions of the same species discovered in other geographic locations. The prevalence and mean intensity levels were 100% and 106.07 parasites per fish, respectively. The monogenean parasites discovered throughout this examination were recorded and the data obtained was summarized.
