A checklist of chigger mites (Acariformes: Trombiculidae) of Southeast Asia

Chigger mites (Acariformes: Trombiculidae) of Southeast Asia, including Myanmar, Malaysia, Brunei, Singapore, Indonesia, Thailand, Cambodia, Vietnam, and the Philippines have been revised based on reference data and examination of type materials in European collections of chiggers. For 450 species of 49 genera synonymy, collection data on types, lists of known host species and lists of countries are given. The lists of hosts include in total 649 valid species and subspecies of mammals, birds, reptiles, amphibians, and arthropods. Two new synonyms were established: Doloisia (Doloisia) Oudemans, 1910 (= Doloisia (Trisetoisia) Vercammen-Grandjean, 1968, syn. nov.) and Gahrliepia lui Chen and Hsu, 1955 (= Gahrliepia (Gateria) octosetosa Chen, Hsu and Wang, 1956, syn. nov.). Twenty-seven new combinations were proposed: Walchia (Ripiaspichia) biliranensis (Brown, 1997), comb. nov., Walchia (Ripiaspichia) huberti (Upham and Nadchatram, 1968), comb. nov., Walchia (Ripiaspichia) parmulaseta (Brown, 1997), comb. nov., and Walchia (Ripiaspichia) serrata (Brown and Goff, 1988), comb. nov., transferred from Gahrliepia Oudemans, 1912; Farrellioides consuetum (Womersley, 1952), comb. nov.
