Sulabanus nigricolor (Pic, 1922), comb. n.

(Fig. 65)

Xylobanus nigricolor Pic 1922: 14.

Type material. Holotype. Female. S. Celebes, Bua–Kraeng, 5000´, Febr. 1896. H. Fruhstorfer lgt.

Differential diagnosis. Sulabanus nigricolor is concolorous dark brown to black, without any bright patch on the elytra and resembles several other species from which cannot be differentiated without examination of male genitalia. Only one female is available and therefore sufficient diagnostic characters are not available for comparison with other species of the genus.

Description. Body dark brown, without yellow patch in elytra. Head partly hidden by pronotum. Frontal interocular distance 1.50 times eye diameter. Pronotum flat, 1.13 times wider that long. Elytra parallel–sided, 3.25 times longer than width at humeri. Ovipositor with fused coxites and paraproctal baculi, vagina membranous, spermaduct more robust at base, very thin apically, spermatheca well sclerotized (Fig. 65).

Measurements. BL 8.1 mm, HW 2.0 mm, PL 1.2 mm, PW 1.36 mm, Ediam 0.54 mm, Edist 0.62 mm, EL 6.5 mm.

Distribution. Sulawesi, known only from the type locality in Bua–Kraeng.

Remarks. Xylobanus nigricolor is transferred to the genus Sulabanus on the basis that all its external characters match those of Sulabanus and the structure of female genitalia. This species is known only from the female holotype and it is therefore impossible to accurately classify this species in the proposed species groups until a conspecific male is found. Therefore we prefer to leave this species as status incertae sedis in Sulabanus. We do not have any other material from the Bua–Kraeng (today Wawakraeng) mountain range and considering the diversity of Sulabanus and the fact that we have not found any widespread species in the available material, we prefer not to arbitrarily apply this name for any of the species recently collected in the mountainous areas of Sulawesi.
