Rhabdoplea Karsch, 1893

Rhabdoplea Karsch 1893: 54, 69.

Type species.

- Rhabdoplea munda Karsch, 1893: 70, designated by Kirby, 1910: 147.

Description.

-Rather wide frontal ridge, with well-defined margins and very weak fastigial constriction; parabolic fastigium with sharp margins and carinulae and arcuate sulcus behind middle. Pronotal sculpturing distinctive, including well-defined parallel lateral carinae and longitudinal callose striations. Micropterous and macropterous forms occur; latter with rather narrow tegmina and wings with loose venation and reticulation, plus presence of a distinct intercalary vein in medial field of tegmina. Epiphallus has rather short lophi, with elongate outer lobes (Fig. 64).

Discussion.

- Rhabdoplea s. str. now contains only the widespread R. munda Karsch, 1893, and the closely related R. angusticornis Uvarov, 1953 (ANGOLA). They share the same characteristic structure and sculpturing of pronotum and tegminal morphology described above. The medial field of the tegmina has a more transparent membrane and a rather looser reticulation than is usually found in Sumba spp.
