Pace, R., 2014, Aleocharinae from Sabah (Borneo) collected by Guillaume de Rougemont (Coleoptera, Staphylinidae), Linzer biologische Beiträge 46 (1), pp. 727-794 : 732-733

Psephothetemusa rougemonti nov.sp. ( Figs 6 and 79 )

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 1.66 mm. Body shiny, yellowish-red, antennae brown with the three basal antennomeres pale yellow, legs yellow. Second antennomere as long as the first, third shorter than the second, fourth to tenth transverse. Eyes longer than the postocular region in dorsal view. Body devoid of reticulation. Puncturation of the head indistinct, that of the pronotum scarcely visible, except for four strong punctures, two on either side of the midlongitudinal band. Granulation of the elytra fine, evident and very superficial. Basal half of the first free abdominal tergites with imbricate sculpture, second to fourth free tergites covered with salient longitudinal striae, on the fifth free tergite these striae are superficial. Spermatheca: Fig. 79.

C o m p a r a t i v e n o t e s: The form of the spermatheca of the new species presents an affinity with P. introflexa PACE, 2002 from Borneo, but while the apical umbilicus of the distal bulb of the spermatheca of P. introflexa is narrow and long, in the new species the same is wide and short. The distal bulb of the spermatheca of the new species is oval transverse, while in P. introflexa is sub-spherical.

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.
