Parga Walker, 1870

Parga Walker, 1870: 504 (replacement for Amycus Stål, 1855: 353).

Type species.

- Amycus xanthopterus Stål, 1855: 353.

Description.

-Of medium size, slender and elongate. Integument strongly carinate and rugose. Antenna short and broad, clearly divided into basal, medial and apical part, with acutely serrated outer edge (Figs 341-350). Head elongate and acutely conical, strongly carinate above. Fastigium elongate, parabolic, foveolae absent. Pronotum with well developed median and parallel lateral carinae; metazona shorter than prozona, its hind margin obtuse-angular. Tegmina and wings fully developed with acute apices and dense, rough venation and reticulation and numerous intercalary veins. Hind femur narrow; upper lobes of hind knee elongate, lower lobes acute (Figs 351, 352). Apex of male abdomen (Fig. 353) elongated, acute. Internal genital structures in male (Figs 354-356).

Discussion.

-The genus Parga is in need of revision. Three species are known from eastern Africa: P. xanthoptera ( Stål, 1855), P. taeniata (I. Bolívar, 1889), and P. musanae Sjöstedt, 1931 with the possibility that a fourth, P. cyanoptera Uvarov, 1926 (recorded from South Sudan and southern Africa), could also occur there. A tentative key to species is given below.

Key to East African species in the genus Parga

Note: P. cyanoptera Uvarov is similar to P. xanthoptera but differs in having proportionately longer and narrower antennae (Fig. 350).
