Description

Body length 10 mm (Fig. 1a). Antenna with 35 flagellomeres. Scape 1.54 times as long as wide (Fig. 1b). Head narrowed behind eyes (Fig. 2b), matt, sparsely and shallowly punctate on granulated surface. Maximum length of temple 0.63X transverse eye diameter; minimum length of temple 0.53X transverse eye diameter. Width of face 1.18X height of eye (Fig. 1b), in dorsolateral profile very slightly convex, with bulge, sparsely (more densely in the middle) and shallowly punctate on granulated surface; frons the same; interspace between hind half of lateral ocellus and eye and vertex matt, with shallow sparse punctures, 3.36X of transverse ocellus diameter (Fig. 2b). Clypeus not separated from face, sparsely punctate, very slightly projecting anteriorly (Fig. 1b); apical margin of clypeus obtuse. Tentorial pit large and elongate. Malar space 0.76X basal mandible width, its margin banded by rugosity starting from tentorial pit. Lower mandible tooth longer than upper. Occipital carina medially complete, reaching hypostomal carina at base of mandible.

Mesosoma matt. Notauli vestigial (Fig. 2b). Mesopleuron matt, granulated, with weak sparse punctures. Tarsus with apical article not enlarged (Fig. 2a). Claws pectinate till its half with not high teeth (Fig. 2a). Wings infuscate (Fig. 1a). Fore wing with areolet petiolate. Rs intercepting pterostigma before its middle. 2m-cu straight, with single bulla. Hind wing with cu-a intercepted below middle. Metapleurum granulated. Propodeum matt, impunctate, basal transverse carina and costula absent, area superomedia elongate (Fig. 2d). Body with fine moderately dense setae.

Metasoma matt, evenly covered with moderately short dense setae, shallowly punctate. First metasomal tergite 2.6X as long as apically wide; without shallow median longitudinal impression; bordered by lateral longitudinal carinae and dorsal longitudinal carinae (rather good defined in middle (Fig. 2e). Second metasomal tergite slightly elongate (Fig. 2f). Ovipositor straight, stout dorsally, without notch (Fig. 2c), as long as metasomal height.

Coloration (Figs 1, 2). Face, basal part of clypeus, malar space, basal part of mandible, temples around eye yellow. Apical part of clypeus, mandible, frons, vertex and outer part of temple black. Antenna, palps,mostly pronotum, notum (excluding horseshoe spot in its hind part), tegula, veins and pterostigma, coxae, trochanters, tarsi, hind legs entirely, hind part of 1st and 2nd metasomal tergites and entirely further tergites, ovipositor sheath dark brown. Lower part of pronotum, horseshoe spot in hind part of notum, scutellum, postscutellum, propodeum, mesopleurum, femur and tibia of fore and middle legs, 1st and 2nd (excluding their hind parts) reddish.

Diagnosis

This species differs from other species of the genus by the combination of the following character states: head narrowed behind eyes, clypeus not separated from face, margin of malar space banded by rugosity starting from tentorial pit, wings infuscate, claws pectinate till its half with not high teeth (Fig. 2a), basal transverse carina and costula absent, area superomedia elongate (Fig. 2d), ovipositor straight, stout dorsally, without notch (Fig. 2c), as long as metasomal height. This species morphologically closely related to Lathrolestes jennyae Gauld, 1997, Lathrolestes xochiquetzalis Reshchikov, 2011 and Lathrolestes kukulcanis Reshchikov, 2011 (all from Central America) with which it shares similar coloration of clypeus (yellow and black in apical part) and well defined dorsal longitudinal carinae of 1st metasomal tergite. The new species clearly differs from Mexican species by the longer first metasomal tergite (2.6X as long as apically wide versus shorter than 1.6-1.9 X as long in the Mexican species), absence of basal transverse carina of the propodeum and costula (Fig. 2d), ovipositor as long as metasomal height, straight, stout dorsally, without notch (Fig. 2c) and unique coloration (Figs 1, 2) (see description). From the single known Afrotropical species, Lathrolestes ruwenzoricus (Benoit, 1955) the new species is distinguished on the basis of colour ( Lathrolestes ruwenzoricus is entirely black except for reddish fore legs).

Etymology
