Diagnosis. One of only seven species in the Neotropical Region with pale setae on the gena, this species is unique in that its thorax is wholly polished with no microtomentum. Only L. rognesi is close to this species, but the presutural area of thorax has a few patches of microtomentum. Furthermore, the distribution of these two species does not overlap; the former is known from Brazil, Peru, and Venezuela, while the latter is known from Costa Rica, Honduras and Panama.

Description. Male. Frons narrow 0.02 (0.015–0.03/6) of head width at narrowest; anterior eye facets are 1.75x posterior facets (0.63mm and 0.36mm). Fronto-orbital plates silvery to silvery-gold from above, orange to orangebrown from below, plates meet one-quarter way up frons; frontal setae ascend about three-fourths of the way up toward antennal bases; frontal vitta very short, color varies from brown to dark orange, ending one-quarter up the frons; parafacial orange to silvery-orange; gena light gray with a mixture of pale and dark setae, more pale setae to rear, genal groove varies from gray to orange; postgena like gena except all setae pale; pedicel and first flagellomere mostly gray to tan, except junction of pedicel and first flagellomere orange, width of first flagellomere about equal to width of parafacial; ocellar triangle small, black, preocellar area with small brown to black shining streak, median ocellus about twice the diameter of posterior ocelli. Supravibrissal setae ascend about one-third of way up facial ridge. Intrapostocular area with bright white microtomentum; setae below and behind strong postocular row and, on the rest of occiput, pale and weak. The thorax and abdomen of most specimens examined are bright green, in a few specimens, they are bright blue. Front and rear spiracles brown; proepisternal depression with pale setae; legs brown to reddish brown. Base of wing, veins and some cells more or less darkened; basicosta brown, tegula black; subcostal sclerite reddish-brown with pubescence. Upper calypter brown with brown rim, lower calypter with darker disc and almost black rim. Dorsum of thorax all polished, T1–3 and anterior third of T4 of abdomen with microtomentum, the remainder polished. Surstylus medium length, digitate, gradually expanding toward distal end, cercus with gentle curve forward ( Figs. 49, 50 ). Phallus, hypandrium, pre- and postgonite, ejaculatory sclerite, and sternites as in 73, 74, 102–104, 128 respectively.

Female. Characters similar to males except frons 0.23 (0.21–0.24/6) of head width at narrowest. Anterior facets about twice the size of posterior ones (0.58mm and 0.30mm). The ovipositor and spermathecae as in Figs. 140 , 152 .

Distribution. Brazil, Peru, and Venezuela ( Fig. 160 ).

Etymology. The species name is taken from the Latin, nitidus, which means “shining” and is the condition of the presutural area of thorax which is an important character state in this species.
