Description. Total length 4.2–8.2 mm, standard length 4.1–8.0 mm (n=21). Integument brown; basic vestiture of small, light­colored to cupreous scales; scales black in vitta between basal third of interstria 3 and preapical callus; pale yellow scales condensed around eye, in narrow median and broad dorsolateral pronotal vittae (with contour­lines emphasized), in narrow lines behind humeri, on preapical callus, on thoracic flank, along sutures of lateral plates and lateral portion of ventrites. Rostrum 0.71–0.88× length of pronotum, curvature over antennal insertion distinct, dorsum sharply costate medially, portion distal to antennal insertion 0.34–0.38× length of rostrum. Pronotum 0.95–1.17× longer than wide, sides subparallel in basal half, then constricted abruptly and tubulate in front, frontal lobe and disk with pair of protuberances. Elytra 1.39–1.64× longer than wide, humeri 1.26–1.61× wider than pronotum; interstriae 3 and 4 with

tumidity at midlength, preapical callus notably produced for genus. Legs with large, triangular femoral tooth, tibia moderately produced ventrally, base notably curved.

Distribution. The species has been collected at elevations below 1600 m in Guatemala, Nicaragua, Costa Rica, Panama and Colombia.

Specific epithet. A Latin adjective; the humpy hood­wearer.

Discussion. The specimens from the Pacific side of the Cordillera de Talamanca are on average larger (6.6–8.2 mm vs. 4.2–6.6 mm total length) and the elytral vitta of black scales is curved around the median callosity rather than running straight across. The protuberances of the anterior pronotal margin are obsolete in all large­sized specimens from any location. Not included in the type series is a specimen from Cerro San Gil in Izabal, Guatemala (CMNC) with deviating body proportions and non­tuberculate pronotum.
