Eutrichodesmus, the largest genus in the Oriental family Haplodesmidae, is reviewed, redefined and shown to encompass 24 recognizable species, all keyed, including the following nine new species: E. regularis sp. n., E. aster sp. n., E. filisetiger sp. n., E. curticornis sp. n., E. asteroides sp. n. and E. griseus sp. n. from Vietnam, E. distinctus sp. n. from China, E. multilobatus sp. n. from Laos, and E. reductus sp. n. from Sulawesi, Indonesia. This genus is slightly redefined as follows: Gonopod coxae usually abundantly setose ventrolaterally; telopodite usually slender, not enlarged towards end of femorite, but typically with a more or less distinct process or outgrowth laterally, opposite recurvature point of seminal groove; solenomere thereafter usually comprising most of telopodite, sometimes elaborate; seminal groove normally terminating distally to subapically, with or without a hairpad; acropodite normally small to nearly absent.
