Material examined. CHILE: without data, 1 ♀ ( USNM: E.C. Reed coll.); Metropolitan Region: Lagunillas, Cord. II-1977, L. E. Peña leg. 7 ♀ 4 ♂ ( USNM); Alto de Cantillana, 1900 m, XII-1981, 3 ♀ ( USNM); Farellones, 2200 m, 29-III-1983, 1 ♂ ( USNM); Lagunillas, II-2009, leg. R. Pérez de Arce, 4 ♀ 3 ♂ ( EIFC). Diagnosis. Dorsal color, blackish blue ( Fig. 2 ), with a white median line on the head and anterior portion of pronotum, hemelytra with black patches on the anterolateral and posterior edges, membrane smoky, scutellum with a white band on each side, border of pronotum and abdomen (connexiva) white. Ventral color, blackish blue, and some specimens with lighter patches, ostiolar peritreme ivory, border of abdomen white, spiracles black, legs orange until ¾ of femora and remainder blackish blue.

Structure. Pronotum compact, bucculae little passing shortly posteriad of mesocoxae to reaching metacoxae. Female genitalia ( Fig. 6 ): 1st gonocoxae acute and convex posteriorly, each sclerite nearly subrectangular; paratergite VIII subrectagular, longer than wide, apex slightly rounded and nearly transverse, paratergite IX wider than longer, robust, with subtriangular apex. Male genitalia: pygophore in ventral view nearly square shaped, with posterior edges rounded ( Fig. 10 ).

Measurements (mm; mean male, followed by mean female in parenthesis): total length 8.24 (9.31); pronotum: width 2.60 (3.37), length 1.65 (2.33); head: width 1.54 (1.75), length 1.24 (1.59); antennae: I = 0.79, II = 0.87, III = 1.04, IV = 0.99; rostrum: I = 1.09, II = 0.85, III = 0.66, IV = 0.52.

Comment. This species is the most cited in the genus and the most abundant in collections; however several references have been removed because these belong to other taxa (see E. nigroscutellata ).
