DESCRIPTION — MALE: Body length 2.3 mm . Head and mesosoma dark castaneous; metasoma castaneous. Head (Figure 68). Mandible with four apical teeth. Clypeus with median lobe subtrapezoidal; median tooth subangulate; median carina complete apically and straight in profile. Frons weakly coriaceous. Mesosoma. Pronotal disc with anterior margin ecarinate, weakly coriaceous. Metapectal-propodeal complex with lateral and posterior areas ecarinate. Metasoma (Figure 163). Tergal process with very shallow, circular and sublateral pair of depression, 0.5 x as long as tergite II, diverging posterad, with very long and thin setae on lateral area; each depression with small tubercle on its anterior area, conical in longitudinal section, very low, entirely laterad, without pit on top. Hypopygium (Figure 254) with median stalk evenly narrow, 1.3 x as long as hypopygial plate; lateral stalk triangular; posterior margin weakly concave. Genitalia (Figure 480-481).
