Pace, R., 2014, Aleocharinae from Sabah (Borneo) collected by Guillaume de Rougemont (Coleoptera, Staphylinidae), Linzer biologische Beiträge 46 (1), pp. 727-794 : 767

Pseudoplandria confundibilis nov.sp. ( Figs 61 and 233-235 )

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: 1 and 1, same provenance as the holotype (CROU, MSNV).

D e s c r i p t i o n: Length 2.3-2.87 mm. Body shiny, reddish, posterior ¾ of the elytra brown, pygidium yellowish-red, antennae brown with the three basal antennomeres and the eleventh yellowish-red, legs yellowish-red. Second antennomere as long as the first, third shorter than the second, fourth as long as wide, fifth to tenth transverse. Eyes longer than the postocular region in dorsal view. Body devoid of reticulation. Puncturation of head and pronotum dense and very fine. Granulation of the elytra dense and salient, that of the first and second free abdominal tergites very superficial, elongate and forming striae. Aedeagus: Figs 233-234 ; spermatheca: Fig. 235.

C o m p a r a t i v e n o t e s: The aedeagus and spermatheca of this new species are similar to those of P. bellicosa PACE, 2008 also from Borneo. The new species differs in the absence in the male of a curved relief on each elytron, present in P. bellicosa . The internal sclerotised piece of the aedeagus of the new species is short (0.21 mm), whereas that of P. bellicosa is long (0.48 mm), and much wider in ventral view. The proximal portion of the spermatheca is shorter than in P. bellicosa .

E t y m o l o g y: The name of this new species, meaning "mistakable", refers to the possibility of mistaking it for other Bornean species with similar external characters, and that it can only be determined with certitude by examination of the aedeagus and spermatheca.
