Myrmecopella borneensis nov.sp. ( Figs 30 and 138-139 )

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

D e s c r i p t i o n: Length 3.45-3.48 mm. Body shiny, yellowish-red, each elytron with a brown macula extending from the humeral angle to the postero-lateral angle, on the posterior margin of the third free abdominal and a median macula on the fourth tergite; antennae reddish-brown with the basal antennomere yellowish-red, legs yellowish-red. Second antennomere shorter than the first, third longer than the second, fourth longer than wide, fifth as long as wide, sixth to tenth strongly transverse. Eyes shorter than the postocular region in dorsal view. Body devoid of reticulation. Puncturation of the head fine and very superficial. Pronotum finely longitudinally furrowed like the grooves of an old phonographic record. Granulation of the elytra very fine and superficial, that of the abdomen sparse and evident. Aedeagus: Figs 138-139.

C o m p a r a t i v e n o t e s:

The genus Myrmecopella KISTNER & MCNAIRN, 1991 described from Sulawesi, is new to Borneo. The new species differs from hitherto known species in the absence of a median sulcus on the pronotum. The aedeagus of the new species is short and compact, whereas it is long and narrow in the other species.

E t y m o l o g y: The name of the new species is derived from Borneo.
