Description
Description. Female. Body length 5.0 mm. Antennal flagellum with 26 articles. Width to length ratio of scapus 0.75. Head not narrowed behind the eyes, mat. Maximal length of temple to transverse eye diameter ratio 0.86; minimal length of temple to transverse eye diameter ratio 0.57. The ratio of the width of the face to the longitudinal diameter of the eye 0.92; convex, with bulge. Clypeus separated from face by transverse groove (Fig. 57 a); at apex projecting slightly anteriorly; apical margin of clypeus moderately thick. Clypeal foveae small. Malar space as wide as 0.3 of basal mandible width. Occipital carina complete, not interrupted above. Lower mandible tooth longer than upper. Mesosoma. Notaulus distinctly impressed. Lower part of mesopleuron without punctures, mat, rugose. Tarsal claws with three teeth (Fig. 45). Hind tarsus articles length ratio 10: 5: 4: 2: 4. Forewing with areolet petiolate. Second recurrent vein with a single bulla. Nervellus intercepted below middle. Nervulus interstitial. Propodeal carinae partly complete: area basalis and area superomedia present, costula absent (Fig. 35). Metasoma. Mat, with sparse white hairs. First metasomal tergum about tree times as long as broad, without shallow median longitudinal impression; bordered by lateral longitudinal carinae; median longitudinal carinae very short, impressed at base (Fig. 39). Second metasomal tergum transverse. Ovipositor straight, thin, very gradually tapered from base to apex, without notch (Fig. 5). Male genitalia with parameres slightly surpassing apex of metasoma. Color. Female. Body black. Mandibles, base of antennae, legs (except brown 5 th article of fore tarsus, apex of middle tibia and middle tarsus, hind femur, tibia and tarsus), lateral part of 2 nd metasomal segment and almost completely 3 rd metasomal segment yellowish. Stigma brownish (Fig. 57 b). Male as in female.
Discussion
Comments. Differs from the closely related L. nigricollis (Thomson, 1883) (Figs 58 a, b) and L. dentatus Barron, 1994 by coloration: head and mesosoma entirely black except mandibles, palpi and tegulae; partly complete carinae of propodeum (area basalis and area superomedia present but costula absent) (Fig. 35). Clypeus small. Malar space short, as wide as 0.3 of basal mandible width. Lower part of mesopleuron mat, rugose, not punctate,.
