The male is here designated as lectotype and female as allotype. Type holder. British Museum of Natural History ( BMNH ) Size range. Male : 5.5 x 2.7 mm to 7.8 x 3.7 mm ; Female 5.9 x 3.0 mm to 7.9 x 4.1 mm . Description. Body black; ventrites and appendages reddish­black. Head sparsely punctate, mostly smooth, without punctures; eyes reniform, not protuberant, flush with surface of head; frons bisulcate, without punctures. Rostrum as long as head in both sexes, distinctly widened beyond antennal insertions, nearly 3 times as wide as frons at apex, dorsally bisulcate from base to antennal insertions, moderately to densely punctured dorsally beyond antennal insertions; postlabial area with pair of bluntly pointed, forward projecting, weakly divergent projections. Antennae inserted at middle of rostrum in both sexes; club elongate­compact, slightly shorter than funicle; middle and terminal club segments nearly subequal in length, basal club segment slightly longer; funicular segment 1 ovo­globose, slightly shorter than scape; segment 2 shorter than 1, clavate; 3 longer than 2, subequal to segment 1 in length; segment 4 subequal to 2; 5–7 moniliform, subequal. Pronotum smooth, shiny, with some small lateral punctures, with larger punctures at lateral base, with small shallow foveae on each side of middle, with two oblique line­like lateral grooves either side of middle near base; anterior collar weakly defined, band­like. Scutellum wide, nearly twice as wide as long, 4­sided; posterior side broadly rounded. Elytra longer than wide, in dorsal view distinctly narrowed from base to apex, widest at humeri, with weak transverse depression behind scutellum; humeri simple, rounded, moderately protuberant, with dorsal posthumeral hump­like protuberance; striae small, round, deeply impressed at base, becoming smaller and more shallow posteriorly; intervals in basal ½ of elytra weakly convex, becoming flat, smooth and wide posteriorly. Profemora evenly swollen in both sexes. Distribution ( Fig. 7 ). The range of this species extends from southern Mexico to Panama . Comments. This species is easily recognized by the shiny black body and dorsal hump­like posthumeral protuberances (Figs. 64–67). Host plants. Vogt (1992) recorded this species from the alder zone in SW Mexico and stated that it rolls new leaves of Apeiba glabra Aubl. (Tiliaceae) . Specimen data. 59 specimens were examined.
