Pace, R., 2014, Aleocharinae from Sabah (Borneo) collected by Guillaume de Rougemont (Coleoptera, Staphylinidae), Linzer biologische Beiträge 46 (1), pp. 727-794 : 740-741

Malayloeblius borneensis nov.sp. ( Figs 23 and 114-116 )

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

D e s c r i p t i o n: Length 2.3-2.54 mm. Body shiny, brown, base of the free abdominal tergites yellowish-brown, antennae brown, legs yellow with yellowish-brown femora. Antennae clubbed ( Fig. 23 ), eyes reduced. Fore-body devoid of reticulation, that of the abdomen very superficial. Puncturation of the head very superficial, evident and widely spaced between the antennae and with some sparse more evident punctures. Puncturation of the pronotum like that of the head, with strong punctures aligned on each side of the longitudinal median band. Puncturation of the elytra deep with some strong punctures, that of the abdomen very close and very superficial and with strong punctures aligned transversely on all free tergites. Aedeagus: Figs 114-115 ; spermatheca: Fig. 116.

C o m p a r a t i v e n o t e s: In its habitus and the form of the spermatheca, the new species is similar to M. sausai HLAVÁČ & MARUYAMA, 2004 from Malaysia. The aedeagus is clearly different, slender, with parallel sides in ventral view, and with a long flagellum of the internal sclerotised pieces of the aedeagus in the new species, whereas the aedeagus is stumpy and without a flagellum of the internal sclerotised pieces in M. sausai . The distal bulb of the spermatheca is short in the new species, while is very long in M. sausai .

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