Wroughtonilla sabahensis nov.sp. ( Figs 57 and 227 )

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). Paratype: 1, same provenance as the holotype (CROU).

D e s c r i p t i o n: Length 4.4-4.69 mm. Fore-body opaque, abdomen weakly shiny. Body brown, the area of elytra surrounding the abdomen reddish, antennae reddishbrown with the two basal antennomeres and the base of third reddish, legs yellowish-red. Second antennomere shorter than the first, third longer than the second, fourth to sixth longer than wide, seventh as long as wide, eighth to tenth transverse. Eyes longer than the postocular region in dorsal view. Reticulation of head, pronotum and abdomen evident, that of the elytra very superficial. Puncturation of the fore-body close and superficial. Pronotum with a fine median sulcus at the bottom of a depression, and ample lateral concavities. Female sixth free abdominal tergite with a triangular emargination on the posterior margin. Spermatheca: Fig. 227.

C o m p a r a t i v e n o t e s: The new species differs from W. borneensis PACE, 1986 also from Sabah, in the evidently transverse pronotum, whereas it is as long as wide in W. borneensis , and in the three penultimate antennomeres being transverse (elongate in W. borneensis ). The spermatheca of the new species is longer (0.22 mm), than that of

W. borneensis (0.18 mm), with the apical umbilicus of the distal bulb of the spermatheca deep and with a wide base, whereas in W. borneensis it is very short.

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