Lycorina riftensis Rousse & van Noort sp. nov.

( Fig. 4 )

Diagnosis. Black overall with yellow markings; face punctate-granulate with punctation sparser medially; clypeus nearly smooth with ventral margin hardly concave medially; mesosoma largely granulate laterally, densely and finely punctate-rugose dorsally with propodeum coarsely punctate-rugose; anterior transverse carina of propodeum present, medially strong; metasoma punctate reticulate; ovipositor moderately long. Male unknown.

Differential diagnosis. Characterized among Afrotropical Lycorina species by the short antennae and the unique sculpture of mesosoma, with mesopleuron mostly granulate and mesonotum finely rugose-punctate.

Description. Female ( holotype). B 5.0; A 3.4; F 3.4; MD 0.9; OT 1.4.

Colour. Black overall with metasoma hardly lighter, very dark brown, and with yellow markings: orbits, clypeus, dorsal margin of pronotum, tegula, posterior and lateral margins of scutellum, and post-scutellum; apical margins of tergites yellowish; legs yellowish-orange except hind coxa dark brown; wings hyaline, slightly infuscate apically, venation yellowish.

Head. Transverse in dorsal view, temple constricted behind eye; temple, vertex and frons sparsely and finely punctate; face moderately punctate-granulate, punctation strongly sparser medially; clypeus nearly smooth, very superficially punctate with noticeably long hairs, its ventral margin subtruncate and hardly concave medially; malar distance long; antenna short with 22 flagellomeres.

Mesosoma. Pronotum coarsely striate ventrally, granulate dorsally; mesopleuron mostly granulate with moderately dense punctures along anterior and ventral margins, speculum smooth; metapleuron moderately punctate-rugose, background smoother along anterior margin; epicnemial carina reaching half height of mesopleuron; mesonotum densely and finely punctate-rugose, rugosities more distinct along superficial notaulus; scuto-scutellar groove smooth; propodeum coarsely punctate-rugose, with anterior transverse carina medially strong and laterally weakened, in profile abruptly subdivided by the strong apical transverse carina into horizontal anterior and vertical posterior parts.

Metasoma. Deeply punctate-reticulate overall except oblique impressions costulate; ovipositor moderately long.

Male. Unknown.

Etymology. For the type locality, in the Rift Valley province. Noun in apposition.

Type material. HOLOTYPE ♀ H.J.A. Turner Naivasha [ Kenya] 6 36 ( BMNH).
