Lambanus rougemonti nov.sp. ( Figs 37 and 157-158 )

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 7.12 mm. Body shiny, black, antennae brown with the basal antennomeres blackish-brown and eleventh yellowish-red, legs brown with femora yellowish-red. Second antennomere shorter than the first, third longer than the second, fourth to ninth longer than wide, tenth as long as wide. Eyes shorter than the postocular region in dorsal view. Reticulation of head and pronotum superficial, that of the elytra evident, that of the abdomen very transverse and very superficial, except on the fifth free tergite on which the reticulation is weakly transverse and more evident. Puncturation of the head dense and superficial, that of pronotum and elytra also dense, but evident. Spermatheca: Fig. 157 ; female sixth free tergite: Fig. 158.

C o m p a r a t i v e n o t e s: This specimen is clearly not the female of Lambanus borneensis nov.sp. described above, and must be attributed to a new species, because antennomeres eight and nine are longer that wide, the puncturation of the head is also present on the longitudinal median band, there are two large punctures near the anterior margins of the eyes, and the abdominal tergites are transversely reticulate.

E t y m o l o g y: The new species is dedicated to its collector, our colleague, the staphylinid specialist Guillaume de Rougemont.
