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). Paratype. Indonesia. 1♂ 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 1.7-1.8 mm. Head and mesosoma castaneous; metasoma light castaneous or castaneous. Head (Figure 45). Mandible with three apical teeth. Clypeus with median lobe subtrapezoidal; median tooth

subangulate, outlined by carina; median carina distinctly incomplete apically and straight in profile. Frons weakly co-

riaceous. Mesosoma. Pronotal disc with anterior margin ecarinate, weakly coriaceous. Metapectal-propodeal complex with lateral and posterior areas partly carinate. Metasoma (Figure 141). Tergal process with shallow, subcircular and sublateral pair of depression, 0.5 x as long as tergite II, diverging posterad, with setae small and thin on anterior area; each depression with small tubercle on its center, conical in longitudinal section, low, entirely dorsad, with broad pit on top, with small tuft of setae posterad. Hypopygium (Figure 233) with median stalk evenly narrow, 0.83 x as long as hypopygial plate; lateral stalk triangular; posterior margin strongly concave. Genitalia (Figures 422-424). Aedeagal dorsal body with apex lower than parameral apex, wider medially, narrowing progressively apicad; apex with long and bilobed projection on ventral region; apical lobe diamond-shaped. Aedeagal ventral ramus with apex lower than aedeagal dorsal body apex, very slightly bifurcated on apical region; apical region angled and smooth. Digitus small. Genital ring produced, each half straight 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 mami means yam in Tok Pisin.
