Another genus of LBFs (little black flies) Females can not be identified to species
The eyes and face of this genus are densely pilose. The straight face and evenly rounded oral margin are also noticeable, with the frontal prominence very short. The face is black, with the front slightly swollen, and the antennae are short in males and long in females. The thorax is heavily pilose, with a ventral scutellar fringe present, and the anterior anepisternum is bare, (pilose in Trichopsomyia). The fourth sternite of the male is as long as its tergite. Vein R4+5 is straight or nearly so, not strongly dipped or with a spur into cell r4+5. The fore and mid femora have no distinct spines or spurs, the hind trochanter has no ventral spur, and the mesocoxa is without a spur. [4][5]
