Gargaphia opima DRAKE, 1931 :513; MONTE, 1947:232, figs 2, 4; DRAKE & RUHOFF, 1965:229.

Redescription. Head dark brown, short. Five light browncephalicspines; occipitalsclosetotheheadsurface, divergent; median and frontal pair slightly erected, almost half of the size of the occipitals; frontal pair slightly convergent. Antenae long, slender, pilose; scape and pediceL darK brown, aLmost bLacK, distiflageLLomere darKer; basiflageLLomere Light brown; scape two and a haLf Longer than pediceL; basiflageLLomere at Least five times Longer than scape and two times than distiflageLLomere. Bucculae closed in front; rostrum brown, darker at apex; reaching the posterior region of mesosternum. Pronotum black at the disc, distal part of the posterior projection white, tricarinate. Hood small, faintly projected over the head. Paranota biseriate, strongLY reflexed, much at middle; slightly constricted before the middle in some specimens; areolas large, rectangular. Carina foliaceous, edge light brown; areolated, entirely uniseriate, areolas usually larger than the areolas of paranota; median carina slightly higher than lateral carina ( Fig. 4 ), becoming obsolete posteriorly; lateral carina parallel at the disc, slightly convergent in the pronotal posterior projection, extending from the base of the hood to the white area of the pronotal posterior projection. Rostral channel interrupted, sternal laminae with small subrectangular areolas; prosternal laminae straight, parallel; mesosternal laminae straight, divergent; metasternal laminae closed anteriorly, strongly curved, forming an angle, convergent posteriorly; concave in the remainder ( Fig. 6 ). Hemelytra large, twice the lenght of the abdomen; edge dark brown, hyaline costal and sutural area, subcostal and discoidal area blackish, whitish in the young adult; discoidal always whitish at the very posterior edge; transversal blackish nervures in costal, area at the median level of the discoidal area, and before sutural area; this with at least two darker nervures, following the end of subcostal area. Costal area with two areolas anteriorly, three areolas after that, and four in the widest part; areolas larger towards the posterior region, there slightly smaller than those of sutural area. Subcostal area biseriate, areolas subequal in size to those on the pronotal posterior projection. Discoidal area almost one third the Lenght of the hemeLYtra; five to six areoLas in the widest part, at middle; areolas in general slightly smaller than those of the subcostal area. Legs light brown, tarsi blackish, almost black; mesocoxae closer to metacoxae than procoxae. Abdomen dark brown to black, lighter in young adults.
