Orphnebius parabigladiosus View in CoL nov.sp. ( Figs 35 View Figs 34-45 and 148-149 View Figs 146-156 )

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 3.9 mm. Body shiny, head black, pronotum brown, elytra yellowish-brown, abdomen yellowish-red, antennae blackish-brown with the three basal antennomeres reddish-brown, legs yellowish-red. Second antennomere shorter than the first, third longer than the second, fourth to tenth longer than wide. Eyes as long as the postocular region in dorsal view. Body devoid of reticulation. Puncturation of the head reduced to some fine and very superficial punctures near the eyes. Pronotum with only six very evanescent punctures. Granulation of the abdomen salient and fairly dense. Free abdominal tergites concave and bare, male first free tergite with a long thorn on either side, male fifth free tergite strongly punctate. Anterior margin of the pronotum very sinuate posteriorly to its half. Aedeagus: Figs 148-149. View Figs 146-156

C o m p a r a t i v e n o t e s: The habitus of the new species is similar to that of O. bigladiosus ( BERNHAUER, 1915) from Sarawak, of which I have examined the male holotype labelled "Madang, 1000 ft. 2.11.19, Sarawak, ded. Moulton 41, Deroleptus bigladiosus Brnh. , Typus" (FMHNC). The new species differs from it in the short lateral thorns on the abdomen of the male (long in O. bigladiosus ), in the shorter intermediary antennomeres and in the aedeagus curved to the dorsal side, while it is rectilinear in O. bigladiosus . The internal sclerotised part of the aedeagus is composed of two strongly sclerotised pieces in lateral view, whereas in O. bigladiosus only one is strongly sclerotised. The posterior margin of the male sixth free abdominal tergite of O. bigladiosus is tri-lobed with two thorns between the lobes. The posterior margin of the male sixth free tergite of the new species is linear.

E t y m o l o g y: The name of the new species mean "close to O. bigladiosus " from the ancient Greek παρά = near.
