DESCRIPTION — MALE: Body length 2.3 mm. Head and mesosoma dark castaneous. Head (Figure 72). Mandible with four apical teeth. Clypeus with median lobe subtrapezoidal; median tooth rounded; 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. All tergites were lost. Hypopygium (Figure 258) with median stalk evenly narrow, 1.0 x as long as hypopygial plate; lateral stalk triangular; posterior margin straight or nearly so with median elevation. Genitalia (Figures 492-497). Basal margin of wail projection. Aedeagal dorsal body with apex lower than parameral apex, evenly narrow. Aedeagal ventral ramus with apex as

high as aedeagal dorsal body apex; apical region with digitiform projections. Genital ring slightly 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 sirsen means cherry in Tok Pisin.
