Derelina lata nov.sp. ( Figs 21-22 )

T y p e m a t e r i a l: Holotype, Kamerun, Bosum bei Termiten, leg. Tessmann ( MNHUB).

D e s c r i p t i o n: Length 2.4 mm. Body feebly shiny and reddish-brown, elytra yellowish-brown, antennae reddish-brown with the three basal antennomeres and the eleventh yellow, legs yellow. Reticulation of the body superficial. Puncturation of head and pronotum very dense and superficial. Granulation of elytra and abdomen evanescent. Pubescence of the fifth free abdominal tergite less close than that of the anterior free tergites. Spermatheca Fig. 22.

C o m p a r a t i v e n o t e s: According to the revision of the genus Derelina KISTNER & JACOBSON 1979 , the new species has a spermatheca similar to that of D. ghaniensis KISTNER & JACOBSON 1979 . It differs in the very wide spermatheca in all of his parts, except the distal bulb of the spermatheca. The spermatheca of D. ghaniensis is narrow in all of its parts.

E t y m o l o g y: The name of the new species derives from the large size of the spermatheca.
