TYPE MATERIAL — Holotype, ♂, Indonesia. New Guinea ( NW), SE Biak I, 1.VII.1962, J. L. Gressitt & J. Sedlacek Collectors ( BPBM).

DESCRIPTION — MALE: Body length 2.0 mm. Head, mesosoma and metasoma dark castaneous. Head (Figure 92). Mandible with four apical teeth. Clypeus with median lobe ill-defined; median tooth rounded; median carina complete apically and straight in profile. Frons weakly coriaceous. Mesosoma. Pronotal disc with anterior margin ecarinate, weakly coriaceous. Metapectal-propodeal complex with lateral and posterior areas partly carinate. Metasoma (Figure

186). Tergal process with very shallow, subcircular and sublateral pair of depression, 0.35 x as long as tergite II, diverging posterad, with very long and thick setae on lateral area; each depression with large tubercle on its center, conical in longitudinal section, high, entirely dorsad, with small pit on top, with small few setae dorsad. Hypopygium (Figure 276) with median stalk evenly narrow, 1.33 x as long as hypopygial plate; lateral stalk triangular; posterior margin strongly concave and elevated medially. Genitalia (Figures 550-552). Aedeagal dorsal body with apex lower than parameral apex, narrower apically, narrowing abruptly apicad. Aedeagal ventral ramus with apex as high as aedeagal dorsal body apex, very slightly bifurcated on apical region; apical region subangled and smooth. Genital ring straight, each half straight in dorsal view.

FEMALE: Unknown.
