Differential diagnosis. Very similar to L. rufiventris (Magretti) but the female of L. smithi differs by having a pair of robust triangular teeth ( Fig. 6 View FIGURES 1–9 in Smith and Tripotin 2015) medio-apically on the second metasomal sternite. In L. rufiventris the apex of the second sternite is subtruncate and weakly serrate ( Fig. 9 View FIGURES 1–9 ). In addition, the eye in lateral view is about 1.5 ×higher than wide in lateral view (about 1.7 × in L. rufiventris ), the outer surface of the fore tibia is white (brownish yellow in L. rufiventris ) and the mandible is mainly ivory in lateral view (mainly blackish in L. rufiventris ). The male of L. rufiventris is unknown but may be recognised by the nearly entirely dark mandible in lateral view.
Description. See description and illustrations of L. rufiventris sensu Smith and Tripotin in Smith and Tripotin (2015).
Notes. Smith and Tripotin (2015) reported L. rufiventris as new for Thailand and redescribed the species on the basis of a small series comprising both sexes. Unfortunately, the female holotype (not male, see Schulz 1908) is most likely lost ( Carmean and Kimsey 1998), but luckily, the holotype was redescribed by Schulz (1908) and partly figured ( Fig. 2a–d View FIGURES 1–9 ). The holotype of L. rufiventris has only a short subtruncate and weakly serrate protuberance at the apex of the second sternite ( Fig. 2d View FIGURES 1–9 in Schulz 1980); this protuberance fits in with the illustrated one of the females from India ( Fig. 8 View FIGURES 1–9 ). The apex of the female second metasomal sternite has a pair of robust triangular teeth in L. rufiventris sensu Smith and Tripotin from Thailand ( Fig. 6 View FIGURES 1–9 in Smith and Tripotin 2015). Obviously, the series from NE India concerns the real L. rufiventris (see illustrations and redescription above) and the series from Thailand belongs to a new species, L. smithi van Achterberg , sp. nov.
Etymology. The new species is dedicated to Dr David R. Smith (1937–2024) for his lifelong dedication to Hymenoptera , especially Symphyta.
