Machaeridia Stal, 1873

Machaeridia Stål, 1873: 90, 100.

Type species.

- Machaeridia bilineata Stål, 1873: 100, 216, by original designation.

Description.

-As in key to genera, above. A genus closely related to Parga with genitalia of fairly similar structure. Slightly more elongate; integument finely rugose and dotted, not ridged. Antenna broadly ensiform, serrated segments along external edge unspecialized, evenly tapering apically; as long as, or slightly longer than, head and pronotum. Fastigium parabolic, as long as, or slightly longer than broad (Fig. 357). Temporal foveolae absent. Dorsum of pronotum narrow, its surface smooth, weakly tectiform to almost flat; carinae sharp, well developed; lateral carinae straight parallel. Metazona shorter than prozona, its hind margin obtuse-angular, almost rounded. Tegmina and wings fully developed, venation and reticulation dense, intercalary vein of medial area present. Hind wings without a preanal speculum. Hind femur narrow, upper knee lobes much shorter than in Parga , their apices acute. Male subgenital plate acute, of similar structure, but shorter than in Parga . Genital structures (Figs 358, 359) similar to those in Parga .

Discussion.

- Machaeridia Stål contains two species, M. bilineata Stål, 1873 and M. conspersa I. Bolívar, 1889. Both are common throughout eastern Africa.
