Diagnosis.

This species generally is similar to Lathrolestes soperi Reshchikov, 2010, and its ovipositor structure is similar to those of Lathrolestes breviremus Barron, 1994, Lathrolestes erugatus Barron, 1994, and Lathrolestes tolstoyi Reshchikov, 2012 but distinguishable by combination of the following character states: claw simple, yellow maculae between antennal sockets and eye margin little ventral level of antennal sockets, malar space as long as basal mandible width, face 1.5 × as broad as eye, height (Fig. 3B), notaulus not defined (Fig. 3D), propodeum with carinae obliterated (Fig. 3F), tergite 1 without dorsal longitudinal carinae (Fig. 3G), ovipositor straight, stout at base, upper valve rounded and at tip with shallow impression in the middle (Fig. 3H).

Description.

Female. Body length 5.3 mm.

Head. Matt, not punctate, shagreen (Fig. 3C). Face 1.5 × as broad as eye height, projecting in the middle, bulging (Fig. 3B). Clypeus distinctly separated from face by groove, at apex projecting anteriorly (Fig. 3B); apical margin of clypeus thick. Clypeal fovea small. Malar space as long as basal mandible width. Lower mandible tooth longer than upper. Occipital carina complete.

Mesosoma. Matt. Pronotum not punctate. Epomia absent. Mesoscutum finely punctate, matt, with notaulus not defined (Fig. 3D). Mesopleuron finely and sparsely punctate, shagreen (Fig. 3E). Claws not pectinate. Fore wing with R intercepting pterostigma at its middle; areolet not petiolate; vein 2m-cu of fore wing with single bulla. Vein cu-a of hind wing interstitial, with cu-a intercepted by Cu1 below middle. Propodeal carinae oblitirated (Fig. 3F).

Metasoma. Matt, not punctate (Fig. 3I). First metasomal tergite 1.94 × as long as broad apically, convex, without longitudinal dorsal carinae (Fig. 3G). Second metasomal tergite transverse, trapezoidal (Fig. 3I). Following tergites also transverse. Ovipositor straight, stout at base and roundish at tip with shallow impression in the middle (Fig. 3H).

Color. Body mostly black (Fig. 3 A–I). Maculae between antennal sockets and eye margin little ventral level of antennal sockets, mandible except teeth, tegula, legs except coxae and hind femur yellowish (Fig. 3A, B, D). Antenna, hind femur and tergite 3 mostly reddish (Fig. 3I).

Male. Unknown.
