Taxon classification Animalia Hymenoptera Chrysididae

Mahinda borneensis Kimsey, Mita & Pham sp. n. Figs 5, 6, 10, 14

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.
