Pelioptera danumensis nov.sp. ( Figs 12 and 90-92 )

T y p e m a t e r i a l Holotype, Sabah, Danum Valley , B.R.L., f.i.t., 14-16.II.2007, G. de Rougemont leg. ( CROU).

D e s c r i p t i o n: Length 2.57 mm. Body shiny, black, posterior margin of the three basal free abdominal tergites and pygidium reddish-brown, antennae black with the three basal antennomeres brown, legs yellow. Second antennomere shorter than the first, third longer than the second, fourth and fifth as long as wide, eighth to tenth transverse. Eyes longer than the postocular region in dorsal view. Body devoid of reticulation except on the fifth free abdominal tergite where it is very transverse and superficial. Puncturation of the head slightly evident. Granulation of pronotum and elytra very close and superficial, that of the abdomen fine and very superficial. Male fifth abdominal tergite with a postero-median tubercle. Aedeagus: Figs 90-91 ; male sixth free tergite: Fig. 92.

C o m p a r a t i v e n o t e s: The aedeagus of the new species is similar to that of P. bituberculata PACE, 2003 from West Malaysia, but it is clearly more curved to the ventral side and its apical part, in ventral view, is very wide, while it is very narrow in P. bituberculata .

E t y m o l o g y: The new species takes its name from the Danum Valley.
