Key to the subfamilies of Bombycidae in China

1. CuP present in both wings; M stem vestige present in discal cell of forewing; all forewing radial veins except Rs4 arising anteriorly from Rs; hindlegs with one pair of tibial spurs; sclerites of abdominal segment 8 strongly modified. Male genitalia: vinculum cup-shaped; tergal processes reduced in size; valvae reduced, finger-shaped; sacculus long and slender. Larvae with short setae and swollen thoracic segments, with rather clearly well visible anal horn........................ Bombycinae

- CuP absent; M stem vestige lacking in discal cell of forewing; forewing with only four radial veins present with the posterior

two arising posteriorly from Rs; hindlegs with two pairs of tibial spurs; sclerites of segment 8 only slightly modified...... 2 2. Eyes setose; antennae fully pectinate. Male genitalia: valvae often with complex harpal appendages. Larvae with flattened thoracic segments and a long curved anal horn......................................................Prismostictinae

- Eyes naked; antennae distally devoid of well-developed rami. Male genitalia: valvae flattened, usually without harpal appendages but with setose basal. Larvae with narrowed thoracic segments and, if present, anal horn extremely long and curved............................................................................................. Oberthuerinae
