Aleochara (Aleochara) sabahensis nov.sp. ( Figs 63 and 237-238 )

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). Paratypes: 2, same provenance as the holotype (CROU, MSNV).

D e s c r i p t i o n: Length 8.5-9 mm. Body shiny, the abdomen slightly iridescent. Body black, sides of the elytra brown, antennae and legs black, tarsi brown. Second antennomere shorter than the first, third longer than the second, fourth to tenth strongly transverse. Eyes longer than the postocular region in dorsal view. Body devoid of reticulation. Puncturation of head and pronotum umbilicate, evident and close, that of the elytra dense and finer than that of the pronotum, that of the abdomen composed of dense and evident elongate punctures. The disc of pronotum bears four punctures disposed in a square and a lateral puncture. Aedeagus: Figs 237-238.

C o m p e r a t i v e n o t e s: The aedeagus of the new species is similar to that of A. paleonigra PACE, 1999 (olim A. nigra KRAATZ, 1859 ), but the internal sclerotised piece of the aedeagus is different in the two species. In lateral profile a plate in the distal portion of the internal sclerotised piece of the aedeagus is shaped like a bid’s head, whereas in A. paleonigra this plate is sickle-shaped. The internal sclerotised piece of the aedeagus of the new species is less developed in length than that of A. paleonigra . These comparisons are based on my examination of specimens of the type series of A. nigra Kraatz labelled as follows: " Ceylon, J. Nietner, Aleochara nigra Kr " (DEI).

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