Sulabanus rufomarginatus sp. nov.

(Figs. 31–32)

Type material. Holotype. Male. Indonesia, Sulawesi Utara, Dumoga–Bone N. P., July 1985, R. Ent. Soc. Lond., Project Wallace, B. M. 1985–10 ( BMNH).

Differential diagnosis. Sulabanus rufomarginatus is easily recognizable by the light colored margins of the pronotum and the lighter humeral part of the elytra. Other species with lighter humeri are S. brunneus and S. dumongabonensis which differ in the coloration of the ventral side of the thorax and in the shape of the phallus. The erect setae in the middle part of phallus are characteristic of S. rufomarginatus (Figs. 31–34) and were not found in any other species in the genus.

Description. Body with ventral side of thorax yellow, elytra lighter brown in humeral third, margins of the pronotum slightly lighter than pronotal disc, trochanters and basal part of femora light brown; other body parts dark brown to black. Head partly hidden by pronotum. Frontal interocular distance 1.32 times eye diameter. Pronotum flat, 1.1 times wider than long. Elytra parallel–sided, 2.8 times longer than width at humeri. Male genitalia ventrally with erect pubescence at middle part of phallus (Figs. 31–32).

Measurements. BL 8.45 mm, HW 2.50 mm, PL 1.34 mm, PW 1.48 mm, Ediam 0.46 mm, Edist 0.66 mm, EL 6.75 mm.

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

Etymology. The specific epithet refers to the lighter margins of the pronotum.
