TYPE MATERIAL — Holotype, ♂, Indonesia. New Guinea, Neth., Waris, S of Hollandia, 450-500m, 1-18.VIII.1959, sweeping, T. C. Maa Coll., Bishop Museum ( BPBM).

DESCRIPTION — MALE: Body length 4.3 mm. Head and mesosoma black; metasoma dark castaneous. Head (Figure 79). Mandible with four apical teeth. Clypeus with median lobe subtrapezoidal; median tooth subangulate, 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 173). Tergal process with deep, longitudinally elliptical and sublateral pair of depression, 0.57 x as long as tergite II, diverging posterad, with thin, small and long setae on anterior and lateral areas, inner margin of depression strongly higher than median region of tergite II; each depression with large tubercle on its inner area, conical in longitudinal section, high, entirely laterad, with broad pit on top, with small tuft of setae dorsad. Hypopygium (Figure 264) with median stalk evenly narrow, 1.0 x as long as hypopygial plate; lateral stalk triangular; posterior margin strongly concave. Genitalia (Figures 514-516). Aedeagal dorsal body with apex as high as parameral apex evenly wide, narrowing abruptly apicad; dorsal surface projected in lateral view. Aedeagal ventral ramus with apex as high as aedeagal dorsal body apex, deeply bifurcated on apical region; apical region angled and smooth with digitiform projections. Genital ring straight, each half convex in dorsal view.

FEMALE: Unknown.

REMARKS — The median stalk of hypopygium is slightly broken, so the rate of length of median stalk and length of hypopygial plate could be inaccurate.

ETYMOLOGY — The noun in apposition susu means milk in Tok Pisin.
