Zyras (Glossacantha) plenus nov.sp. ( Figs 54 and 218 )

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 9 mm. Body shiny, head black, pronotum blackish-brown, elytra and abdomen yellowish-red, fourth to sixth free abdominal tergites brown, antennae brown with the two basal antennomeres and the base of third yellowish-red, legs yellowish-red. Antennae compressed from the fourth antennomere. Second antennomere shorter than the first, third longer than the second, fourth to tenth as long as wide. Eyes a little longer than the postocular region in dorsal view. Body devoid of reticulation, which is present only on the fourth free tergite on which is very superficial, and on the fifth free tergite on which it is distinct and irregularly polygonal. Puncturation of head moderately dense and superficial, absent on the longitudinal median band, that of the pronotum evident, close on either side of the impunctate longitudinal median band; on the rest of the pronotum the Puncturation is sparse. Puncturation of the elytra a moderately dense and strong, that of the abdomen sparse. Spermatheca: Fig. 218.

C o m p a r a t i v e n o t e s: The distal bulb of the spermatheca has a lateral prolongation as in the spermatheca of Z. inversus PACE, 2001 from India. However the sixth free abdominal tergite of the female is not split to half as in Z. inversus , and the spermatheca is less developed than that of Z. inversus , with the apical umbilicus of the distal bulb shallow, whereas in Z. inversus it is very deep.

E t y m o l o g y: The name of the new species, meaning "full", refers to the distal bulb of the spermatheca, which is normally empty, but in this case appears nearly filled by the thickness of the cuticle.
