Mahinda saltator Krombein 1983 a: 29. Holotype female; Sri Lanka: Sabaragamuwa Prov., Kegalla Dist., Kitulgala, Bandarakele Jungle (USNM).

Diagnosis.

The finely shagreened metasomal terga are most distinctive feature of this species. The dark mesosomal coloration and flagellomere I 3 × or more as long as broad most closely resembles those of Mahinda borneensis . Additional diagnostic features include the midocellus 1.3 midocellar diameters from the nearest eye margin, malar space less than 3 midocellus diameters long, thorax with metallic highlights, and face ventrally converging below ocular margins in front view.

Female description.

Body length 4.0-4.5 mm. Head: face (Figs 11); scapal basin finely, densely transversely ridged, zone of ridging separated from midocellus by punctate band more than 1 midocellar diameter wide; malar space 2.8 midocellar diameters; subantennal distance 0.9 midocellar diameter long; least interocular distance 0.3 × as broad as facial length between midocellus and clypeal apex; eyes convergent above; midocellar to ocular margin distance 1.3 midocellar diameter; hindocellus 0.3-0.4 diameters from ocular margin; vertex least interocular distance 0.7 × ocular width in dorsal view (Fig. 15); flagellomere I 2.8 × as long as broad; flagellomere II 0.9 × as long as broad; flagellomere III 0.7 × as long as broad; flagellomere XI 1.5 × as long as broad; vertex with dense, contiguous punctures. Mesosoma: dorsum with dense, contiguous punctures, transversely striatiform on pronotum and metanotum, longitudinally striatiform on scutum and scutellum; mesopleural punctures separated by 0.2-0.5 puncture diameters; metanotum 0.6 × as long as broad, with small apicomedial angle on either side of midline; propodeum laterally polished, impunctate, posterior surface transversely ridged without medial longitudinal ridge. Metasoma: densely, finely shagreened. Color: head, mesosoma and metasoma black, dorsum of head and mesosoma with faint metallic green to coppery tints; scape red dorsally, brown ventrally; pedicel and flagellomere I yellow, with brown ventroapically; flagellomeres II-III pale brown dorsally, dark brown ventrally; remaining flagellomeres dark brown; coxae yellow, with dark brown patch on anterior surface; femora yellow dorsally, dark brown ventrally; tibiae reddish brown becoming paler basally; tarsi red.
