Diagnosis.

The blackish coloration of the mesosoma and flagellar proportions of borneensis most closely resemble those of saltator , but the highly polished and impunctate metasoma is most similar to that of sulawesiensis . Additionally the posterior and lateral surfaces of the propodeum are smooth without cross-ridging unlike the other species.

Female description.

Body length 4.5 mm. Head: face (Fig. 10); scapal basin finely, densely transversely ridged, zone of ridging separated from midocellus by nearly impunctate band more than 1 midocellar diameter wide; malar space 3.4 midocellar diameters long; subantennal distance 0.8 midocellar diameter long; least interocular distance 0.4 × as broad as facial length between midocellus and clypeal apex; eyes slightly converging above in front view; midocellar to ocular margin distance 1.8 midocellar diameters; hindocellus 0.5 diameters from ocular margin; vertex least interocular distance 0.8 × ocular width in dorsal view (Fig. 14); flagellomere I 2.7 × as long as broad; flagellomere II 0.8 × as long as broad; flagellomere III 0.7 × as long as broad; flagellomere XI 1.4 × as long as broad; Mesosoma: dorsum and mesopleural punctures separated by 0.5-1.0 puncture diameters, polished between; pronotum subequal in length to scutum plus scutellum; metanotum 0.6 × as long as broad, with small apicomedial angle on either side of midline; propodeum with two posteromedial angles, lateral tooth large, conical, posterior surface polished, with minute punctures near dorsal margin, without medial longitudinal or transverse ridges.
