Stilicoderus riedeli n. sp.

Holotype (♂): Irian Jaya, Sorong Prov., Batanta Island, 10 m, sifted, 30.X.1996, leg. A. RIEDEL (NHMW) .

P a r a t y p e s: 18 exx., same data as holotype; 5 exx., same locality and collector as holotype, but 150 m, 2.XI.1996; 2 exx., Irian Jaya, Sorong Prov., Salawatti Island, Solol, 200–300 m, 6.–7.XI.1996, sifted, leg. A. RIEDEL (20 exx. NHMW, 5 exx. CRO) .

Description

Body length ca. 4.1 mm. Proportions of holotype: length of head: 51; breadth of head: 65; diameter of eye: 24; length of antenna: 105; length of pronotum: 59; breadth of pronotum: 51; length of elytron: 67; breadth of elytra: 65; metatibia: 58; metatarsus: 35.

In colour, facies, sculpture etc. similar to S. hieroglyphicus and its allies, the legs entirely testaceous, but smaller than any species of this group described so far.

Male: abdominal sternites as in S. hieroglyphicus . Aedoeagus see Fig. 2.

Differential diagnosis

S. riedeli is distinguished from all other members of the hieroglyphicus group by its small size and by the conformation of the ventral blade and spatulate parameroid lobes of the aedoeagus. It inhabits the same island as the similar species S. laticeps, described above, but was taken at lower altitudes.
