( Figures 5 and 6 )

Holotype ♀, Gabon, Reserve de La Lopé, 14-15.XII.1995, leg. L. Bartolozzi and S. Taiti, num. mag. 1784, n. coll. 14816, MSNF.

Description

Length: 1.37 mm. Body shiny, yellowish-red, elytra yellow, abdomen brown with pygidium yellowish-red, antennae yellowish-brown with the three basal antennomeres yellowish-red. Eyes much shorter than the post-ocular region in dorsal view. Second antennomere shorter than the first, third shorter than the second, fourth to ninth very transverse. Reticulation of head and pronotum weakly pronounced, that of the elytra obsolete, that of the abdomen slightly transverse and well visible on three basal free tergites, diffused on the fourth and obsolete on the fifth. Puncturation of the fore-body dense and not well pronounced. Spermatheca: Figure 6 .

Comparative notes

The habitus and the colour of the body of the new species are very similar to those of C. flavipenne Cameron, 1944 from Zanzibar, of which I have examined the female holotype labelled ‘ Zanzibar, Seaweed, Cameronium flavipenne Cam. , Type’ (NHML). The spermatheca of C. flavipenne is very narrow, that of the new species very broad. The new species also differs from the unique male of C. guineense Pace, 1988 from Guinea-Bissau, in the yellowish red colour of the fore-body, and not brown as in C. guineense .
