Description. Holotype. Male. Length 5.7 mm. LFW 4.6 mm.

Colors. Body black; metasoma dark castaneous; legs castaneous; wings hyaline, veins castaneous.

Head. Head as long as wide, quadrate. Frons weakly coriaceous, densely puncticulate; frontal line absent. Vertex slightly convex. Clypeus broad with median lobe rounded, median tooth small, apical margin smooth, median carina short in profile. Mandible with three apical teeth, teeth with different size, upper tooth mesad, uppermost much smaller than others. Eye strongly bulging. Ocelli large, triangle with distal edges.

Mesosoma. Dorsal pronotal area long. Notaulus present, complete, strongly converging posterad. Parapsidal signum well delimited. Mesoscutellum as long as wide, posterior margin convex; mesoscutum-mesoscutellar sulcus weakly arched, narrow, shallow, without fovea on side edge. Axilla subtrapezoidal, deep, small. Metanotal trough mostly imbricate, with few foveae, metanotal fovea oval; median region wide, narrow, with posterior margin straight. Metapectal-propodeal complex short, posterior margin convex; metapostnotal median carina absent, metapostnotum irregularly foveolate. Metapectal-propodeal complex polished. Paraspicular sulcus irregularly foveolate; lateral carina of metapectal-propodeal carina absent; lateral surface of propodeum imbricate, inferior region foveolate. Propodeal declivity foveolate.

Metasoma. Petiole short. Hypopygium with plate long, posterior margin almost straight, flap present. Genitalia: paramere straight. Basivolsella apical inner margin smooth. Basiparamere with apical dorsal projection large, apex convex. Cuspis with apical margin with two apical calli, dorsal larger than other, dorsal end long. Aedeagus with two apical lobes, ventral lobe large; dorsal lobe long; subapical membrane absent; aedeagal dorsal cover wide.

Female. Known.

Diagnosis. Allotype. Female. Length 5.9 mm. Color. Body castaneous, metasoma dark castaneous. Mandible with two apical teeth. Clypeus extending back frons, median lobe with apical margin slightly concave, apical margin with bristles, median carina present and short, angled just before apical margin. Eye dark, elliptical, with about 13 facets. Malar space shorter than eye length. Frons aciculate, punctures sparse. Head quadrate with sides parallel, vertex slightly concave, 1.07 × as long as wide. Dorsal pronotal area with sides nearly parallel, anterior margin with median emargination. Maximum width of metapectal-propodeal complex 1.27 × its minimum width. Mesopleuron without longitudinal carina dividing dorsal and lateral faces. Midtibia strongly spinose. Metasoma slightly longr than head and mesosoma together, petiole short.

Material examined. Types: Holotype ♂, INDIA, Karnataka, Chikmagalur, Farm of Coffee Research Station , 12.I.2000, extracted from stem borer larvae of Xylotrechus quadripes from tunnels of infested coffee stems, H.G. Seetharama col. ( UFES nº 11128) . Allotype 1 ♀, same data as holotype ( UFES nº 11129) . Paratypes: 6 ♀, 6 ♂, same data as holotype ( UFES nº 11116, 11117, 11118, 11119, 11120, 11121, 11122, 11123, 11124, 11125, 11126, 11127). New material : 1 ♂, THAILAND, Petchaburi Kaeng Krachan NP Panernthung / km27, 12°49.302’N, 99°22.263’E, 28.xii.2008 – 4.i.2009, Malaise trap, Sirichai leg. ( QSBG) GoogleMaps .

Comments. This species was first described based on specimens from Arabica coffee infested with the white stem borer, Xylotrechus quadripes Chevrolat. The male of this species is promptly recognized by having the clypeus rounded; the notaulus complete; the metapostnotum irregularly foveolate; the hypopygium with a long plate, with a flap and the posterior margin almost straight.

Remarks. The illustrations of the body, genitalia and hypopygium were done using paratypes.

Distribution. Oriental ( India, Thailand).
