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.

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.
