Pseudolathra ullrichi nov.sp.

( Figs 2 fb, 2al, 2av)

Material examined Holotype, 2 & 3 paratypes: 18 V 78, PNG /EHProv., Umg. Kainantu, Onerunka / PAPUA Nlle. Guinée, W. G. Ullrich [ MHNG, 1 paratype in CRO].

Description: Length: ca. 7 mm; length of fore-body: 4.1 mm. Body black, femora and tibiae pitchy black, mouthparts antennae and tarsi dark brown. Fore-body: Fig. 2 . Head sub-quadrate, slightly transverse (1 x 1.1 mm), the anterior margin with a single puncture behind antennal tubercles, one anterior and one posterior puncture on inner margin of eyes, 4-5 unequal punctures near postero-lateral angles and a single row of rather large punctures along posterior margin, the disc impunctate. Pronotum scarcely elongate (1.4 x 1.3 mm), with discal series of 6 punctures and arcuate lateral series of 4 punctures. Elytra a little elongate (1.5 x 1.3 mm), with 3 series of punctures. Abdomen more sparsely and irregularly punctured than that of P. magna , the interstices devoid of microsculpture.

Male: posterior margin of sternite VII very broadly, shallowly, arcuately excised, laterally with a small tuft of bristles; deep narrow emargination of sternite VIII extending to ½ the length of sternite, the margin of emargination finely and sharply bordered; aedoeagus: Fig. 2 al, 2av.

This species belongs to the Nigerrima group. It is about the size of P. nigerrima , but differs externally by its dark legs, longer elytra with finer punctures of the discal series. It is larger than the black species from New Guinea described by Last and redescribed by ASSING (2014).
