Diagnosis.

Closely allied to L. amoenus van der Vecht, 1935 with the following characters in common: head higher than wide, the sides slightly flattened; anterior lateral angles of pronotum each produced into a sharp spine; metanotum with sharp median tooth; propodeum, as seen in profile, with short blunt tooth above the apical tooth; metasomal petiole relatively long and slender (Van der Vecht 1935, fig. ia); the morphological characters separating the two species are as follows: frontal fovea deeper and slightly smaller, circular or even a little wider than long, distinctly defined; frons not carinate; median part of scutellum regularly rounded posteriorly, without prominent angles; punctures on head and thorax very slightly coarser than L. amoenus ; body black, without yellow spots, and with the following parts red: an ill-defined transverse spot at base of clypeus, a rather wide transverse band at anterior margin of horizontal surface of pronotum, a small spot in upper part of mesepisternum below tegulae, a transverse band on scutellum, interrupted by the black median groove, and the greater part of the metasomal petiole (van der Vecht 1963).
