Pseudoplandria collaris nov.sp. ( Figs 62 and 236 )

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 3.33 mm. Body shiny, yellowish-red, antennae yellowishred with the two basal antennomeres and apical half of the eleventh yellow, legs yellowish-red. Second antennomere as long as the first, third shorter than the second, fourth and fifth longer than wide, sixth as long as wide, seventh to tenth transverse. Eyes longer than the postocular region in dorsal view. Body devoid of reticulation. Puncturation of head and pronotum fine and very superficial. Granulation of elytra and abdomen fine, very superficial and evident. The disc of the pronotum bears four large punctures disposed in a square. Base of the third and fourth free abdominal tergites with strong elongate punctures. Spermatheca: Fig. 236.

C o m p a r a t i v e n o t e s: The only other known species with a spermatheca similar to that of this new species is P. kinabaluicola PACE, 2008 also from Borneo, but the antennomeres four to seven are transverse in the new species, whereas they are elongate in P. kinabaluicola . The distal bulb of the spermatheca of the new species is more developed than that of P. kinabaluicola and the proximal portion of the spermatheca is shorter in the new species, longer in P. kinabaluicola .

E t y m o l o g y: The name of the new species, meaning "relating to the neck" refers to the very transverse pronotum.
