Stiliderus brendellianus View in CoL n. sp.

Holotype (♂): Indonesia, C. Sulawesi, Palu Palolo, Lindu N. P ., 25.– 27.VIII. 1990, leg. A. RIEDEL ( SMNS) .

P a r a t y p e: 1 ♀, same data as holotype ( CRO) .

Derivatio nominis

This new species is dedicated to my friend MAR- TIN BRENDELL, who was the first to find this genus in Sulawesi, and helped me in many ways at the Natural History Museum in London for thirty-three years.

Description

Body length 4.6 mm. Proportions of holotype: length of head: 70; breadth of head: 71; diameter of eye: 24; length of antenna: 152; length of pronotum: 73; breadth of pronotum: 60; length of elytron: 73; breadth of elytra: 82; metatibia: 78; metatarsus: 41.

Black, abdomen pitchy brown; labrum and antennae rufo-testaceous; palpi and legs paler, testaceous.

Male: apical margin of sternite VII very shallowly, arcuately excised; emargination of sternite VIII broad and shallow. Aedoeagus see Fig. 20 View Figs .

Female: tergite X see Fig. 26 View Figs , broadly emarginate, with a single long seta on each apico-lateral lobe and an apical row of shorter setae.

Differential diagnosis

This new species runs to S. brendelli from eastern Central Sulawesi in my key to the Celebesian species (1996: 725). It differs from S. brendelli in its very slightly less transverse head, in the slightly finer and denser cephalic puncturation, in its uniformly testaceous legs (meso- and metafemora more or less strongly infuscate in S. brendelli ), in the near total absence of visible pubescence on pronotum and elytra (scattered long setae interspersed with numerous finer and shorter hairs in S. brendelli ), and in the male sex characters: shallower emargination of sternite VIII and the shape of the ventral blade of the aedoeagus, the apex of which is somewhat spatulate in ventral view.
