status

sp. nov.

Stilicoderus laticeps View in CoL n. sp.

Holotype (♂): Irian Jaya, Sorong Prov., Batanta Island,

Waylebet, 800 m, sifted, 29.X.1996, leg. A. RIEDEL ( NHMW).

P a r a t y p e s: 17 ♂♂ / ♀♀, same data as holotype (12 exx.

NHMW, 5 exx. CRO).

Description

Body length ca. 4.5 mm. Proportions of holotype: length of head: 65; breadth of head: 73; diameter of eye: 28; length of antenna: 135; length of pronotum: 61; breadth of pronotum: 56; length of elytron: 73; breadth of elytra: 71; metatibia: 67; metatarsus: 40.

Colour and sculpture as in S. hieroglyphicus , the femora testaceous like the tibia.

Male: abdominal sternites as in S. hieroglyphicus , the apical margin of abdominal sternite VIII very shallowly and broadly excised. Aedoeagus see Fig. 1 View Figs .

Differential diagnosis

This new species can only be separated with certainty from S. hieroglyphicus and many congeners by the conformation of the aedoeagus. It is readily identified by the shape of the lateral lobes and the long, slender asymmetrical apex of the ventral blade ( Fig. 1 View Figs ). Externally it can only be distinguished from S. hieroglyphicus by its narrower pronotum and elytra, which make the head appear considerably broader. In this it is similar to S. cephalicus n. sp. described below.
