Diagnosis. Setae on gena pale (as in Fig. 1 ); basicosta brown, upper and lower calypters brown; anterior edge of presutural area of the thorax with a strong band of whitish microtomentum (as in Fig. 13 ). Known from Colombia, Costa Rica, Ecuador, Honduras, and Panama. Very similar to L. woodi , see comments under that species.

Description. Male. Frons 0.018 (0.015–0.02/5) of head width at narrowest; anterior eye facets very large, 1.55x larger than posterior facets, (0.68mm, 0.44mm). Fronto-orbital plates bright silvery, plates meet midway up frons, eyes almost touch; frontal vitta dull orange, extending only about one-fourth of the way up the frons, obliterated by fronto-orbital plates; frontal setae ascend about half way up toward the vertex. Parafacial bright silvery except a small area of orange on the anteroventral corner; gena bright silvery with mostly black setae, except pale setae extend up from the postgena along the ventral edge. Antenna with pedicel brown, lower edge orange and first flagellomere silvery-gray, about one-third broader than parafacial; ocellar triangle medium size, black in color, anterior ocellus slightly larger than posterior ocelli. Intrapostocular area bright silvery; area behind and below postocular row pale and weak (as in Fig. 3 ); occiput, upper edge and upper midsection shining black, the remainder with whitish microtomentum. Body color variable, most specimens bright blue or green, but some are purple and a few coppery.

Thoracic spiracles brown, relatively large; legs brown to dark brown; proepisternal depression usually with pale setae; rim and disc of upper and lower calypters brown; base of wing with veins and cells dark brown, rest of wing hyaline; basicosta and tegula brown and black respectively; subcostal sclerite brown with brown pubescence; presutural area of the thorax with heavy whitish microtomentum, remainder of thorax polished (as in Fig. 13 ). Abdomen, rear third of T4 and all of T5 polished; surstylus medium length, parallel sided ( Figs. 53, 54 ). Phallus, hypandrium, pre- and postgonite, ejaculatory sclerite, and sternites as in 77, 78, 108–110, 130 respectively.

Female. Characters similar to males except frons 0.24 (0.23–0.25/5) of head width at narrowest; anterior eye facets fairly large about 1.7x posterior facets (0.52mm and 0.30mm). The ovipositor and spermathecae are as in Figs. 142 , 154 .

Other Material Examined. Material examined, but not labeled paratypes included 296 females ( INBIO), as follows : Alajuela Province, 2; Cartago Province, 1; Guanacaste Province, 97; Heredia Province, 2; Limon Province, 10; Puntarenas Province, 178; San Jose Province, 6.

Distribution. Known from Colombia, Costa Rica, Ecuador, Honduras and Panama ( Figs. 159 , 160 ).

Discussion. The setae on the gena are very fine and it can be hard to see the pale setae mixed with dark setae. If they are missed, specimens will key to L. vulgata . The specimens from Colombia and Ecuador are distant from where most specimens were found, but they still appear to be L. pulverulenta . Barcode data was obtained for nine specimens, all from Costa Rica. The barcodes for six of these specimens placed them in a distinct group ( Fig. 161 ). It would be useful to get barcode data for specimens from Colombia, Ecuador or other areas to see if they match the Costa Rican species.

Etymology. The name is taken from the Latin pulvis meaning “dust” which refers to the heavy dusting on this species in the presutural area of the thorax
