Summary 
Based on differences in male genitalia, and the presence cr absence 
of tergal glands, species of Epilampra are divided into 2 genera. 
Species in which the males have tergal glands on segments i and 2 
are placed in the genus Poeciloderrhis Stal. Species with males lacking 
glandular modifications on the tergites are restricted to the genus 
Epilampra Burmeister. Poeciloderrhis is placed in the tribe Poecilo- 
derrhini.
