Hessemydas, gen. nov.

Type species: Hessemydas parkeri sp. nov.

Head: Proboscis with elongate prementum, subequal to length of labella. Antennae typical of subfamily, apicoflagellomere expanded, clavate, with apical knob (Figs. 1, 6).

Wing: Sc and R1 long, costa ending at M1; R5 ending in R1 closing cell R4.

Male terminalia: Epandrial lobe 2 x as long as wide (Figs. 2, 4, 7, 9), phallus tapered with single tip (Figs. 5–10).

Etymology: Hesse, honoring the late Dr. A.J. Hesse, from the South African Museum for his studies of Afrotropical Mydidae, with mydas, refers to the Mydidae .

Diagnosis: This new genus is placed in the Leptomydinae that currently includes two other Afrotropical genera (Bowden 1980), Eremomidas Semenov and Leptomydas, being most similar to Leptomydas . However, each epandrial lobe in Hessemydas is greater than 2 x as long as wide, whereas in Leptomydas, the each epandrial lobe is slightly wider than long (Richter and Ovshinnikova 1996). Both genera share the tapered phallus with a single tip.
