Diagnosis. Female L. nigroviride   can be recognised by the following diagnostic combination: size large (7.0– 8.1 mm); head and mesosoma golden; gena wider than eye; mesoscutal punctures sparse between parapsidal lines (i= 1–4 d), sometimes sparse laterad of parapsidal line (i= 1–2 d); mesepisternal punctures distinct, sparse (i= 1–2.5 d) ( Fig. 24 View FIGURE 24 A); lateral carina reaching or nearly reaching oblique carina ( Fig. 2 View FIGURE 2 B); and metasomal terga black-brown, tomentum and apical fringes. They are superficially similar to L. obscurum   , which is smaller (4.9–5.9 mm) with weak propodeal carinae, and sparse apical fringe hairs on metasomal terga.

Male L. nigroviride   can be recognised by the following diagnostic combination: size large (7.0– 7.5 mm); head and mesosoma golden green; flagellomeres elongate (length/width ratio = 1.60–1.87); mesoscutum polished due to weak microsculpture, punctures sparse between parapsidal lines (i= 1–4 d); mesepisternal punctures distinct; metasomal terga blackish brown; and S 3 and apicolateral portions of S 4 with very dense plumose hairs. Male L. obscurum   are similar but have relatively sparse hairs on the metasomal sterna.
