Undescribed genus #1 Figs 422-426

Based on species AUS-01 of F.C. Thompson, in prep.

Diagnosis.

Basoflagellomere strongly widened, more or less triangular. Arista pilose.

Discussion.

This species has first been recognized as undescribed by Dr. F.C. Thompson, who is preparing a description of it. As the species posesses some unique characters not found in any other species of Microdontinae, the present authors feel that it belongs in a new genus. These characters are: basoflagellomere strongly widened and more or less triangular; arista pilose; phallus dorsobasally with long projection; epandrium with dorsolateral ridge. Other interesting characters are the undeveloped mouthparts (shared with Masarygus) and the lateral carinae on the face.
