Gymnobothrus sellatus Uvarov, 1953.

Material.

-ANGOLA: Moxico dist. rivers Lumeje; Munhango, Lungue Bungu, Mu-Simoj; Bihe dist. Cohemba. Also, Tundavala; Bruco; 15 mi. N. Sa de Bandeira; River Langiliko.

Description.

-Size (in mm): males 16-19, females 18-21. Similar to other subspp. in size, general appearance, and elongate antennae; differs in following respects: Frontal ridge broadly sulcate from above ocellus downwards, flat and punctured elsewhere, its fastigial constriction weak (Fig. 193). Fastigium of vertex strongly concave, pentagonal, about as long as broad; temporal foveolae fairly large, incompletely marginated below (Fig. 194). Pronotum markedly more constricted ( ‘sellate’) than in other subspecies; lateral carinae obliterated between first and second sulci and in posterior 2/3 of metazona, strongly callose elsewhere (Fig. 195). Lateral pronotal lobes much deeper than long, their surface very uneven (Fig. 196). Coloration brown, mottled with ivory-white, buff, and grey; lateral pronotal lobes with typical pattern brown above, ivory-white below. Tegmina grey with a series of brownish spots along discoidal field and beyond it. Abdomen reddish-brown below; upper face of hind femur with large brownish-black spots, outer face brown above, yellow below, while lower outer area brown. Hind tibia yellowish touched with black on inner and outer face.

Discussion.

-The specimens from Bruco are less sellate and coriaceous and more like those from Tanzania.
