Allied to L. angularis van der Vecht, 1935 mainly distinguished by the shape of clypeus which is very weakly marginalized at the apex, with apical teeth replaced by two undeveloped tubercles; punctures on frons thicker than those in L. angularis and on thorax visibly larger, punctuation of metasoma approximately as in L. angularis (Giordani Soika 1991).	en	Li, Ting-Jing, Carpenter, James M.

0B5AC8DE8965EBE1D0DBD34CF56F772D.taxon	diagnosis	Diagnosis. Very closely allied to L. spiniger de Saussure, 1867 (van der Vecht 1935: 165), but the horizontal part of the propodeum more distinctly punctate, the punctures not much closer, but slightly larger, and better defined; the sides of the propodeum more shiny between the punctures (rugose and rather dull in L. spiniger), the transverse ridge at apex of propodeum more pronounced, as seen in profile forming a more distinctly projecting tooth; swollen part of metasomal petiole relatively longer, nearly half as long as the petiole; second metasomal segment relatively longer (length: width = 1.2: 1, in L. spiniger = 1.1: 1); metasomal petiole red, with narrow yellow apical band; legs ferruginous, coxae and trochanters dark brown to black, fore femur I with vague yellow spot at apex, mid and hind femora fuscous at base, hind tibiae fuscous at apex, tarsal segments 2 - 5 of mid legs and 1 - 5 of hind legs fuscous (van der Vecht 1963).	en	Li, Ting-Jing, Carpenter, James M.
