Reshchikov, Alexey, 2012, Lathrolestes (Hymenoptera, Ichneumonidae) from Central Asia, with a key to the species of the tripunctor species-group, Zootaxa 3175, pp. 24-44 : 30-33

Lathrolestes kozlovi sp. nov.

Figs 14–17 .

Diagnosis. This species differs from L. buccinator and L. orbitalis by the reduced propodeal carinae; the tentorial fossa is not large and elongate; the mesopleuron is evenly covered with distinct, deep punctures; the areolet is large, almost rhombic ( Fig. 49 ); claws are elongate and narrow with very short, hair-like teeth ( Fig. 50 ); the ovipositor is short ( Fig. 48 ); the is body reddish-yellow with the metapleuron brownish ( Fig. 17 ).

Description. Holotype female. Body length 8 mm. Antenna with 38 flagellomeres. Scape 0.52X as long as wide. Head cubic, not nerrowed behind eyes, matt, roughly punctate. Maximum length of temple 0.83X transverse eye diameter; minimal length of temple 0.73X transverse eye diameter. Face as wide as height of eye; flat; without bulge. Clypeus separated from face by impression, at apex projecting slightly anteriorly; apical margin of clypeus not thin. Clypeal foveae not large. Malar space 0.5X basal mandible width. Occipital carina medially complete. Lower mandible tooth longer than upper.

Mesosoma matt. Notaulus absent. Anterior part of propleuron with striations. Mesopleuron shining, coarsely punctate ( Fig. 14 ); punctures separated by about 3 times puncture diameter. Postnotum not bordered by carinae. Claws elongate, pectinate with small teeth ( Fig. 50 ). Mid tibia with apical tooth (character state is shared by several species of Perilissus ). Fore wing with areolet relatively large, rhombic, slightly petiolete ( Fig. 49 ). Radius intercepting stigma at its middle. Second recurrent vein with only one bulla. Nervellus intercepted below middle. Nervulus interstitial. Propodeum with carinae incomplete. Only area petiolaris distinctly raised, divided by longitudinal carina anteriorly ( Fig. 15 ). Dorsal longitudinal carinae weak, defined only posteriorly.

Metasoma matt, punctate, setose. First metasomal tergum 0.71X as long as apically wide; without shallow median longitudinal impression; bordered by lateral longitudinal carinae; dorsal longitudinal carinae not defined. Second metasomal tergum with basal oblique impression and short carinae at angles. Epipleuron separated from 5th tergum only at base, epipleura of subsequent terga not separated. Ovipositor straight ( Fig. 48 ). Male is unknown.

Color: body uniformly reddish-yellow ( Fig. 17 ), as in various taxa inhabiting deserts.
