The genitalia of the British species have been described and figured by 
Pierce (1938). The two following species possess male genitalia of the 
same character but differ considerably by a well-developed uncus, a less 
developed sacculus, and a peculiar, bristled vinculum. Perhaps further 
data on generic characters of Stenoptilia from other countries will make it 
possible in the future to divide the group in separate genera. 
Key to the Papuan species of Stenoptilia 
1. Larger species: 26 — 28 mm, light fuscous; fore wing: dorsal cilia of first segment 
mostly mixed with blackish scales, conspicuously darker than ground colour 
- iriana spec. nov. 
Smaller species: 17 — 20 mm, brownish; fore wing: if dorsal cilia of first segment 
mixed with dark scales, then these cilia not conspicuously darker than ground 
colour galaotostacta spec. nov.
