Key to species of Madachauliodes

1. Antennae with flagellum entirely dark brown; hindwing MA vein weak, not connecting to Rs ( Fig. 3 ); male ectoproct strongly narrowed posteriad with acutely produced apex ( Fig. 27 ); median plate of male tenth gonocoxite without additional ventral projection ( Fig. 29 ); female ectoproct strongly produced posterodorsad ( Fig. 30 )................. M. torrentialis Paulian

- Antennae yellow or yellowish brown on proximal half; hindwing MA vein distinct, distally connecting to Rs ( Fig. 1 ); male ectoproct stout with obtuse apex ( Fig. 13 ); median plate of male tenth gonocoxite with additional ventral projection ( Fig. 15 ); female ectoproct stout with obtuse or posterodorsally prominent apex ( Fig. 18 )..................................... 2

2. Antennae entirely yellowish brown; male ectoproct as long as ninth tergum ( Fig. 15 ); median plate of male tenth gonocoxite acutely pointed on posterolateral corners and with a subtriangular ventral projection ( Fig. 16 ); female ectoproct stout and slightly prominent on posterodorsal corner ( Fig. 18 ).................... M. bicuspidatus Liu, Price & Hayashi , sp. nov.

- Antennae yellow on proximal half but much darker on distal half; male ectoproct much shorter than ninth tergum ( Fig. 22 ); median plate of male tenth gonocoxite rounded on posterolateral corners and with a plate-like ventral projection ( Fig. 23 ); female ectoproct stout with obtuse apex ( Fig. 25 ).......................................... M. ranomafana Penny
