Description

Length 6.8– 7.5 mm. Fore-body slightly opaque, abdomen shiny. Body brown, head and fourth and fifth free abdominal tergites blackish-brown, pronotum reddish, antennae reddish-brown with basal, second, and apex of the eleventh antennomeres yellowish-red, legs brown with base of the middle and posterior femora and anterior femora yellowishred. Eyes longer than the post-ocular region in dorsal view. Second antennomere shorter than the first, third longer than the second, fourth to ninth longer than wide and slightly compressed. Reticulation of the fore-body strong, that of the abdomen distinct. Puncturation of the fore-body of the male dense and very weak, distinct in the female. Disc of the head concave in male, convex in female. The head bears a protruding tubercle between the antennae in both sexes. Pronotum with a shallow impression on each side of the pronotum. The male has a shallow median impression posteriorly, this impression extending to the anterior margin in the female. Fifth free tergite of the male with small protruding tubercles, which are absent in the female. Aedeagus: Figures 29 and 30 ; spermatheca: Figure 31 .

Comparative notes

In the slightly opaque fore-body and strongly arched spermatheca the new species is comparable to Z. kilifensis Pace, 1996 from Kenya. It differs in the distal bulb of the spermatheca being compressed and longer than that of Z. kilifensis and in the greater length of the spermatheca, 0.37 mm, whereas in Z. kilifensis it measures 0.25 mm. The proximal portion of the spermatheca of the new species is short, that of Z. kilifensis forms an almost complete coil. The male of Z. kilifensis is not known.
