Latuspina Monzen, 1954 : Melika, 2010: 18 .

Description. Body length usually less than 3.0 mm; body color black to brown; female antenna with 12 or 13 segments; male antenna with 13-segments; pedicel as long as scape; pedicel and scape flattened, more than two times as wide as flagellomeres; F1 strongly incised and swollen anteriorly; malar sulcus absent; mesosoma glabrous; notaulus absent or if present not reaching anterior margin of mesoscutum; transscutal articulation absent medially; mesoscutum emarginate and elevated posterolaterally above dorsoaxillar area, fused with mesoscutellum; mesoscutellum without foveae, with anterior scutellar depression; mesopleuron coriaceous, with irregular wrinkles; propodeum without or with weak, fragmented, indistinct lateral propodeal carinae or curved outwards; metasoma strongly compressed laterally; ventral spine of hypopygium with two subapical lateral projections; lateral subapical projections of ventral spine of hypopygium with 5-11 setae extending far beyond apex.

Diagnosis. Ventral spine of hypopygium with two subapical lateral projections; lateral subapical projections of ventral spine of hypopygium with 5–11 setae extending far beyond apex.
