This species is closed related to L. pleuralis (Thomson, 1883) but differs from it by the height of the teeth of the claws and in whole colouration of the hind femur which is brownish with yellowish apical and basal parts (Fig. 18 b). Description. Holotype female. Body length 5 mm. Antenna with 25 flagellomeres. Scape 0.83 X as wide as long. Head not narrowed behind eyes, matt. Maximum length of temple 0.7 X transverse eye diameter; minimum length of temple 0.4 X transverse eye diameter. Face as wide as eye height, convex, with bulge. Clypeus separated by transverse groove (Fig. 19), at apex projecting anteriorly; apical margin of clypeus not thin (Fig. 19). Clypeal fovea not large and elongate. Malar space 0.42 X basal mandible width. Occipital carina medially incomplete. Lower mandible tooth longer than upper. Notaulus distinct at anterior edge of mesoscutum. Lower part of mesopleuron impunctate, polished, slightly shagreened, with sternaule-like impression. Upper part of mesopleuron slightly striate. Claws pectinate, teeth as long as apical tooth. Radius intercepting pterostigma before its middle. Areolet petiolate. Second recurrent vein with single bula. Nervulus slightly postfurcal. Hind wing with cu-a intercepted by Cu 1 very low under middle. Propodeal carinae absent (Fig. 20). Metasoma polished, impunctate, pubescent. First metasomal tergite 0.64 X apical width, with deep median longitudinal impression at base; lateral longitudinal carinae complete, dorsal longitudinal carinae defined at basal half. Second metasomal tergite transverse. Ovipositor straight, with subapical notch. Colour. Female.
