Material examined. Holotype, ♂: Ethiopia, Ambo , 20. VI. 1990, shrubs including Acacia, A.F. Emelyanov leg.; dissected; deposited in ZIN.

Description. Head, pro-, and mesonotum pale ochre yellow with dense brown speckles, mesonotum with brighter yellowish tinge ( Figs. 4–5 ). Face somewhat darker in upper part, areas on sides of frons and around ocelli lack speckles. Proepimeron with brownish streak. Forewing semi-transparent with brown speckles more dense on clavus, on costal margin, and in apical half. Veins mostly of the same colour as membrane, transverse veins in apical part brown.

Apex of crown and anterior margin of pronotum angular ( Fig. 5 ). Median keel very narrow, but distinct on face and pronotum and almost invisible on mesonotum.

Abdominal apodemes of 2 nd tergite in male with angular lobes separated by narrow round notch; sternal apodemes narrow, slightly bent inwards, separated by wide more or less rectangular notch ( Fig. 44 ). Penis in side view almost parallel-sided in apical half, only slightly tapering apically ( Fig. 45 ). Pygofer process in side view narrow, gradually pointed apically ( Fig. 46 ), in back view strongly diverging, rather wide, with rounded tip ( Fig. 47 ). Style tip shape is typical for the simplex group ( Fig. 48 ).

Body length (including tegmina): ♂, 3.8 mm.

Diagnosis. Presently, seven species of the simplex group are known ( Linnavuori, 1978). In M. simplex head and pronotum more angular, pygofer process shorter, style bent inwards; also, it is somewhat larger; M. gigas and M. lamellaris are much larger; in M. chinai , M. capensis and M. kanongensis penis stem gradually tapering apically in side view ( Figs. 49–51 ); M. bakeri known only from female holotype is distinctly larger and more robust.

Host. “On shrubs including Acacia ”.

Etymology. The Latin word “ tincta ” means “speckled”; thus, the name indicates the colouring feature of this species.

The turneri group. Veins of forewing with black tubercles, ovipositor short, only slightly extends beyond the end of genital segment.
