with small black spot. Forewings fairly shiny, transparent, with dense brown speckles partially merged with each other around proximal parts of subapical cells and in apical part. Areas at the level of middle of forewing and before apex almost entirely unspotted and form two more or less distinct transparent transverse stripes.

Apex of crown and anterior margin of pronotum sharply angular; crown in dorsal view in middle of same length or somewhat shorter than next to eyes. Face with weakly developed longitudinal median keel in apical half, pronotum always with distinct median keel, keel on mesonotum absent.

2 nd valvulae of ovipositor fused, each with 3–4 preapical teeth situated close to each other and with one proximal tooth separated from others by wide notch (Fig. 28).

Body length (including forewings): ♀, 4.0–4.1 mm.

COMPARISON WITH RELATED SPECIES.Very small species. Differs from all seven species from the M. simplex group listed in Linnavuori [1978] by smaller size. Differs from M. tincta , which is similar in size, in more sharply angular apex of crown and anterior margin of pronotum, shiny forewings, and dark pattern (Figs 25–26 and 29). Differs from M. semuliki sp.n. in coloration and somewhat smaller size.

ETYMOLOGY. Species name derives from the name of the country, Uganda, where it was collected.
