MICROLEPID OPTERA OF NEW GUINEA 
species (niphobola spec, nov.) with identical neuration and with genitalia 
of the same type, but without costal fold in male. Some of the Indian 
species have the male antenna notched beyond base, and not at J / 4 as in 
all the following species from New Guinea. In our opinion this difference is 
not sufficient for the separation of the last named species from Hermenias; 
the costal fold is a secondary sexual character and is little reliable, as this 
group of characters usually is subject to considerable variation. 
The following species belongs also to this genus: Spilonola asbolandra 
Meyrick 1938 (Trans. Ent. Soc. Lond., vol. 87, pp. 509—510) from Papua. 
Besides, one more species from Papua, four species from Australia and 
three from Ceylon have been described before.
