Stiliderus germanus Rougemont 2015, 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 s: 3 ♂♂, 4 ♀♀, same data as holotype (5 exx. SMNS, 2 exx. CRO).

Body length 6.0– 6.5 mm. Proportions of holotype: length of head: 98; breadth of head: 100; diameter of eye: 30; length of antenna: 198; length of pronotum: 97; breadth of pronotum: 86; length of elytron: 96; breadth of elytra: 113; metatibia: 104; metatarsus: 51.

Black, labrum pitchy with margins rufescent; palpi rufo-testaceous; antennae dark brown, antennomere I infuscate; legs pitchy black, pro- and mesotibia and all tarsi dark reddish brown.

Male: apical margin of abdominal sternite VII broadly and very shallowly concave; sternite VIII see Fig. 25, with a moderate emargination, the surface anterior to the emargination broadly, concavely depressed; apical margin of tergite X with a small median emargination. Aedoeagus see Fig. 18.

Female: abdominal tergite X very deeply emarginate, as in S. yangbesar, forming two long, pointed apico-lateral lobes.

This species only differs externally from S. yangbesar Rougemont 1996 described from north Sulawesi in its slightly lesser size (S. yangbesar ca. 7 mm), slightly denser puncturation of the head, and the aedoeagus. It appears to be the sister species of the northern Celebesian species S. yangbesar in central Sulawesi.
