Doryloxenus borneensis, Pace, 2014

Pace, R., 2014, Aleocharinae from Sabah (Borneo) collected by Guillaume de Rougemont (Coleoptera, Staphylinidae), Linzer biologische Beiträge 46 (1), pp. 727-794 : 739-740

Doryloxenus borneensis nov.sp. ( Figs 16 and 98-100 )

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

D e s c r i p t i o n: Length 1.51-2 mm. body shiny, reddish-brown, pubescence of the abdomen golden yellow, legs yellow. Antennae very short Fig. 16 . Body without reticulation. Puncturation of the head sparse, fine, very superficial and lacking on the longitudinal median band, puncturation of the pronotum sparse, fine and evanescent, absent on the longitudinal median band, that of the elytra fine, sparse and evident. Aedeagus: Figs 98-99 ; spermatheca: Fig. 100.

C o m p a r a t i v e n o t e s: On the basis of the 4-segmented fused tarsi, the build of the antennae, the presence of eyes and the shape of the spermatheca the new species is attributed to the genus Doryloxenus WASMANN, 1898 from tropical Africa and Asia. The new species is clearly distinct from its geographically nearest congener, D. groveri Kistner & Jacobson, 1975 from Selangor (West Malaysia) in the absence of a deep apical umbilicus of the distal bulb of the spermatheca and by the proximal portion of the same being not folded up and narrowed as in D. groveri .

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