Sulabanus nigricordatus sp. nov.

(Figs. 25–26)

Type material. Holotype. Male. Indonesia, Sulawesi Utara, FOG 25, G. Ambang F. R., 1200 m, 31 July 1985. R. Ent. Soc. Lond., Project Wallace, B. M. 1985–10. Tray 2 ( BMNH).

Differential diagnosis. Sulabanus nigrocordatus is placed in the S. mamasensis group on the basis of the shape of male genitalia. The body is dark colored, without any yellow patch. S. nigrocordatus resembles, in colouration and size of eyes, S. barclayi , but these species differ in the shape of the basal half of the phallus (Figs. 23–26). Although male genitalia of S. cordatus and S. nigrocordatus are very similar (Figs. 21–22 and 25–26) these species differ in colouration and the relative size of eyes.

Description. Body dark brown, without any bright patch in elytra. Head partly hidden by pronotum. Frontal distance between eyes 1.38 times eye diameter. Pronotum flat, 1.17 times wider that long. Elytra parallel– sided, 2.85 times longer than width at humeri. Male genitalia with widened middle part of phallus and short slender apical part (Figs. 25–26).

Measurements. BL 8.3 mm, HW 2.29 mm, PL 1.26 mm, PW 1.48 mm, Ediam 0.46 mm, Edist 0.64 mm, EL 6.55 mm.

Distribution. Sulawesi, known only from the type locality in the Northern Sulawesi province.

Etymology. The specific epithet is derived from the characteristics of this species–the wide middle part of the phallus and the concolorous black body.
