TYPE MATERIAL — Holotype, ♂, Papua New Guinea. NE New Guinea, Umboi I, 1 km N Awelkom , 600m, 21-28.II.1967, G. A. Samuelson, Malaise Trap, Bishop ( BPBM).

DESCRIPTION — MALE: Body length 4.2.0 mm. Head and mesosoma black; metasoma dark castaneous. Head (Figure 57). Mandible with four apical teeth. Clypeus with median lobe subtrapezoidal; median tooth rounded, outlined by carina; median carina distinctly incomplete apically and straight in profile. Frons strongly coriaceous. Mesosoma. Pronotal disc with anterior margin coarse, strongly coriaceous. Metapectal-propodeal complex with lateral and posterior areas carinate. Metasoma (Figure 155). Tergal process with shallow, subtriangular and sublateral pair of depression, 0.26 x as long as tergite II, diverging posterad, with very long and thick setae on lateral area, inner margin of depression slightly higher then median region of tergite II; each depression with large tubercle on its inner area, conical in longitudinal section, very low, entirely anterad, with broad pit on top, with small seta posterad. Hypopygium (Figure 246) with median stalk 1.9 x as long as hypopygial plate; lateral stalk triangular; posterior margin straight or nearly so. Genitalia (Figures 460-462). Basal margin of paramere with rounded projection. Aedeagal dorsal body with apex lower than parameral apex, evenly narrow; apex with very long and hooked projection on ventral region. Aedeagal ventral ramus with apex as high as aedeagal dorsal body apex; deeply bifurcated forming two sheets, ventral sheet narrow, long and crenulated, dorsal sheet broad, small and smooth. Cuspis large. Genital ring straight, each half straight in dorsal view.

FEMALE: Unknown.
