Tribe Trichopterygini

Trichopteryx carpinata ( Fig. 20 ). The gnathos arms are sclerotized, slightly produced, and partly fused with the tegumen. The base of the anal tube with its rather long, very weakly sclerotized subscaphium is connected to the gnathos and membrane of the fultura superior (which is ventrad of the anal tube).
