Figs 45–51.
Diagnosis. This species differs from the closely related L. obliquus sp. nov. by shape of areolet, and coloration. It can also be separated from L. buccinator (Holmgren, 1857) by its smaller size, second recurrent vein intercepted areolet before its middle, metasomal tergites with course deep punctures (Fig. 49), and coloration: face, clypeus, temples, lower part of mesopleuron, lateral parts of propodeum and lateral parts of metasomal tergites yellowreddish (Figs 45, 47).
Description. Female. Body length 6 mm. Antenna with 26–28 flagellomeres. Scape 0.58 × as long as wide. Head not narrowed behind eyes, swollen, matt, with fine deep punctures. Maximum length of temple 1.14 × transverse eye diameter; minimum length of temple 0.7 × transverse eye diameter. Face 1.27 × height of eye; convex, medially bulging, with fine deep punctures (Fig. 46). Clypeus not separate from face by impression or suture; at apex projecting strongly anteriorly; apical margin of clypeus moderately thick. Clypeal foveae small. Malar space 0.4 × basal mandible width. Occipital carina complete, not interrupted above. Lower mandible tooth longer than upper.
Notaulus absent. Mesopleuron, mesonotum with course deep punctures, matt (Fig. 51). Claws pecinate at base. Fore wing with areolet petiolate (Fig. 48). Radius intercepting stigma at its middle. Second recurrent vein intercepted areolet before its middle; with a single bulla. Nervellus intercepted below middle. Nervulus interstitial. Propodeal carinae complete (Fig. 45).
Metasoma matt, sparsely setose. First metasomal tergite 0.86 × as long as apically wide; without median longitudinal impression; bordered by lateral longitudinal carinae; median longitudinal carinae defined at base (Fig. 49). Metasomal tergites with fine deep punctures. Ovipositor stout at base, without notch (Fig. 50). Male genitalia with paramers slightly surpassing apex of metasoma.
Color. Body brownish (Fig. 47). Maculae on the head reddish. Legs yellow-reddish. In male face, clypeus, temples, lower part of mesopleuron, lateral parts of propodeum and lateral parts of metasomal tergites yellowreddish.
