Pace, R., 2014, Aleocharinae from Sabah (Borneo) collected by Guillaume de Rougemont (Coleoptera, Staphylinidae), Linzer biologische Beiträge 46 (1), pp. 727-794 : 757-758

Drusilla borneoclara nov.sp. ( Figs 46 and 184 )

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 5.84 mm. Body shiny, yellowish-red, sides and posterior margin of the elytra brown, antennae brown with the three basal antennomeres yellowish-red, legs yellowish-red. Second antennomere shorter than the first, third longer than the second, fourth as long as wide, fifth to tenth transverse. Eyes longer than the postocular region in dorsal view. Fore-body devoid of reticulation, that of the abdomen very transverse and very superficial, but on the sixth free tergite very transverse and evident. Puncturation of the head evident and not very dense, absent on a narrow longitudinal median band. Puncturation of the pronotum strong and denser on either side of the median line, sparse on the rest of the surface, that of the abdomen fine and sparse. There is a salient tubercle between the antennae. Spermatheca: Fig. 184.

C o m p a r a t i v e n o t e s: The habitus of the new species is similar to that of D. aerea ( CAMERON, 1933) also from Borneo, but the spermatheca is different. The proxi-

mal portion of the spermatheca of the new species is bisinuate, whereas in D. aerea the same portion is rectilinear.

E t y m o l o g y: The name of the new species "Borneo pale" refers to the mostly yellowish-red colour of the body.
