Abstract
Tayalopsyche gen. nov. of Psychidae is described from the mountain region of Taiwan based on Tayalopsyche spinidomifera sp. nov. The genus somewhat resembles Bacotia, but is more plesiomorphic than it in having the cellula intrusa in the forewing, well-developed uncal lobes and an invaginated pouch on the diaphragma of the male genitalia. The larval case of the new species is unique in being ornamented with elongate plant fragments erected on its outer surface.
