Genus Eutonnoiria Alexander, 1940

Eutonnoiria Alexander, 1940: 794 (original description).

Type species: Bruchomyia edwardsi Tonnoir, 1939: 38 (by monotypy). Tonnoiromyia Alexander, 1940 : page; incorrect name used by Alexander (1979, p.197) syn. nov.

Species included: Eutonnoiria edwardsi [ Uganda].

Diagnosis. Males with paired, elongate vasa deferentia, aedeagus subtriangular in dorsal view, ejaculatory apodeme elongate, flared (trumpet-shaped) at base. Antenna with more than 100 antennomeres but antenna not obviously longer than in other genera; individual segments shorter, subequal length, ascoids V-shaped. Subcosta ends in wing area, CuA2 almost straight.

Comments. Eutonnoiria edwardsi fits quite well into the pattern of features described for the Old World Nemopalpus s.str. Main differences between genera are the drastically increased number of flagellomeres, and bifid (V-shaped) ascoids. Wing (Fig. 2 c) with Sc terminating in wing area with sc-r cross vein, wing tip at R4, CuA2 almost straight as in Bruchomyia and longer than in Nemopalpus ; radial and medial forks with short basal stem at about middle of wing, medial fork distal of r-m.

Male genitalia with vasa deferentia (which can be traced to mid segment 5 where they terminate) widening slightly. Ejaculatory duct comparatively short, i.e. less than 15% of the length of ejaculatory apodeme. Ejaculatory apodeme similar in shape to those of Neotropical Bruchomyia , and longer than the aedeagus; its apex, where the ejaculatory duct opens into the proximal part of the aedeagus, appears slightly twisted. Gonostylus broad, subtriangular, epandrium elongate, rectangular, cerci large ( Fig. 5 a).
