TYPE MATERIAL — Holotype, ♂, Papua New Guinea. New Guinea, SE Mamai Pltn, E. of Port Glasgow, 150m, 31.I.1965, R. Straatman, Ligth Trap, Bishop ( BPBM).

DESCRIPTION — MALE: Body length 1.9 mm. Head, mesosoma and metasoma castaneous. Head (Figure 55). Mandible with three apical teeth. Clypeus with median lobe subtrapezoidal; median tooth angled; median carina complete apically and angled in profile. Two teeth on hipostomal carina rounded. Frons strongly coriaceous. Mesosoma. Pronotal disc with anterior margin ecarinate, strongly coriaceous. Metapectal-propodeal complex with lateral and posterior areas partly carinate. Metasoma (Figure 153). Tergal process with deep, longitudinally elliptical and lateral pair of depression, 0.73 x as long as tergite II, diverging posterad, with very long and thick setae on lateral area, 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 laterad. Hypopygium (Figure 244) with median stalk evenly narrow, 1.0 x as long as hypopygial plate; lateral stalk triangular; posterior margin convex and with median elevation. Genitalia (Figures 454-456). Aedeagal dorsal body with apex lower than parameral apex, evenly wide, narrowing abruptly apicad; dorsal surface projected in lateral view; apical lobe small and diamond-shaped, apex with narrow, long and angled projection on ventral region. Aedeagal ventral ramus with apex as high as aedeagal dorsal body apex, slightly bifurcated on apical region; apical region subangled and smooth. Digitus small. Genital ring produced, each half straight in dorsal view.

FEMALE: Unknown.

ETYMOLOGY — The noun in apposition pepa means pepper in Tok Pisin.

TYPE MATERIAL — Holotype, ♂, Papua New Guinea. New Guinea, SE Mt. Bosavi, 1800m 5. VI.1973, Gaya coll. ( BPBM). Paratype. Papua New Guinea. 1♂ New Guinea, SE Mt. Bosavi, 1800m, 6-10. V.73, J. L. Gressitt, Malaise Trap, Bishop Museum ( BPBM).

DESCRIPTION — MALE: Body length 2.9-3.2 mm. Head and mesosoma dark castaneous; metasoma castaneous. Head (Figure 56). Mandible with four apical teeth. Clypeus with median lobe subtrapezoidal; median tooth truncate, 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 partly carinate. Metasoma (Figure 154). Tergal process with shallow, subtriangular and sublateral pair of depression, 0.45 x as long as tergite II, diverging posterad, with thin, small and long setae on anterior and lateral areas; each depression with small tubercle on its inner area, evenly wide in longitudinal section, very low, entirely anterad, with small pit on top, with small tuft of setae dorsad. Hypopygium (Figure 245) with median stalk evenly narrow, 1.25 x as long as hypopygial plate; lateral stalk triangular; posterior margin strongly concave and excavated medially. Genitalia (Figures 457-459). Basal margin of paramere with rounded projection. Aedeagal dorsal body with apex lower than parameral apex, wider medially, narrowing progressively apicad; apex with very small, angled projection on ventral region. Aedeagal ventral ramus with apex lower than aedeagal dorsal body apex, deeply trifurcated on median apical region; apical region subangled and smooth. Genital ring straight, each half convex in dorsal view.

FEMALE: Unknown.

ETYMOLOGY — The noun in apposition pike means chewing gum in Tok Pisin.
