Lathrolestes aitmatovi sp. nov.

Figs 1–6 , 48–50 .

Diagnosis. This species differs from the similar L. orbitalis by the face coloration ( Fig. 3 ) and the clearly defined punctures of the metasoma; from the closely related L. hovdensis it differs in the lateral profile of the propodeum ( Fig. 6 ), with an impression in the apical part, the mesopleuron less coarsely punctate ( Fig. 1 ), the first metasomal tergum strongly convex, and the parameres projecting far beyond the metasoma ( Fig. 2 ).

Description. Body length 8–10 mm. Antenna with 36 flagellomeres. Scape 0.56 times as long as wide. Head not narrowed behind eyes, matt. Maximum length of temple 1.13X transverse eye diameter; minimum length of temple 1.07X transverse eye diameter. Face 1.15X height of eye; convex, with bulge. Clypeus separated from face by impression; projecting anteriorly; apical margin of clypeus obtuse. Clypeal foveae not large. Malar space 0.36X basal mandible width. Lower mandible tooth longer than upper. Occipital carina medially complete.

Mesosoma matt. Mesopleuron matt, coarsely punctate ( Fig. 1 ). Notaulus defined basally. Claws elongate, pectinate, hair-like teeth. Fore wing with areolet not petiolate. Radius intercepting stigma before its middle. Second recurrent vein with single bulla. Nervellus intercepted below middle. Nervulus interstitial. Propodeum with carinae partly absent ( Fig. 5 ). Area superomedia obliterated, elongate, narrow and fused with area basalis. Lateral profile of propodeum ( Fig. 6 ) with impression in apical part.

Metasoma matt, sparsely setose, distinctly punctate. First metasomal tergum strongly convex, 0.68X as long as apically wide; without shallow median longitudinal impression; bordered by lateral longitudinal carinae; dorsal longitudinal carinae absent. Parameres narrow, longer than aedeagus ( Fig. 2 ).

Color. Body mostly black ( Fig. 4 ). Face yellow, black medially ( Fig. 3 ); legs and metasomal terga from second yellow-reddish.

Etymology. This species is named in honor of Chyngyz Aitmatov, Kirgiz and Russian writer.
