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.
