Undescribed genus #2 Figs 427-432

Based on species MCR-2 of F.C. Thompson, in prep.

Diagnosis.

Basoflagellomere bifurcate. Abdomen more or less parallel-sided, slightly constricted between tergites 2 and 3.

Discussion.

This species has first been recognized as undescribed by Dr. F.C. Thompson, who is preparing a description of it. This taxon resembles Carreramyia in the bifurcate antenna, the wing venation and the structure of the male genitalia. It differs from that genus by the more or less flat vertex (strongly produced in Carreramyia ), the short pilose hind tibia (long pilose in Carreramyia ), and the more or less parallel-sided, slightly constricted abdomen (triangular in Carreramyia ).

Diversity and distribution.

Only known from one species, collected in Costa Rica.
