Description. Holotype male. Length 14.9 mm width 8.0 mm. Color: Dorsal surface yellowish brown, mostly tomentous. Pronotum shiny on apex and anterolateral angles, tomentous elsewhere, with 1 longitudinal, black vitta on each side of midline; vittae not covering midline or lateral margin, each with a circular, yellowish brown marking at middle. Elytra with black, irregular markings distributed mostly on costae and sides. Ventral surface, including legs, light to dark brown, abdominal sternites bicolored. Head: Frons densely punctate; punctures round, deep, moderate in size, confluent laterally, densely setose; setae yellowish, moderate to long. Clypeus subrectangular, sides strongly raised, lateral declivity strongly expanded; apex moderately reflexed, truncate in dorsal view, sinuate in frontal view; surface as on frons. Antennal club longer than stem. Pronotum: Surface moderately densely punctate; punctures round to lunulate, small, densely setose; setae short, yellowish. Sides strongly convergent anteriorly, anterior corners with few rugae. Base in front of scutellum strongly emarginate. Scutellum sparsely punctate, punctures small. Elytra: Surface moderately densely punctate, striae bearing 3–4 irregular rows of small, lunulate or irregular punctures, moderately densely setose, setae short to moderate. Costae weakly developed. Apical declivity and posterior sides weakly rugose. Pygidium: Surface subconcentrically striate; striae dense, discontinuous, moderately setose; setae short to moderate, yellowish. Legs: Surface densely setose; setae long, yellowish. Protibiae slender, apical and medial teeth closer to each other than to basal tooth, basal tooth subobsolete. Meso- and metatibial carinae moderately developed. Metatarsi longer than metatibiae. Metatibial spurs slender, apices sharp. Venter: Mesometasternal process weakly compressed laterally, extending anteriorly well beyond mesocoxae, apex rounded. Mesepimera, metasternum, and metacoxae densely setose, setae as on legs. Metasternum rugose, densely setose laterally, sparsely punctate and setose at middle; median sulcus strongly impressed. Abdomen in lateral view weakly concave.

Allotype. Female. Similar to holotype except in the following: Length 12.4 mm; width 8.7 mm. Head: Frons slightly raised at middle, sparsely setose, setae short. Clypeal sides weakly raised, apex weakly reflexed. Antennal club shorter than stem. Pronotum: Shiny on anterior half, tomentous on posterior half, moderately setose, setae short to moderate in length. Legs: Protibiae robust. Metatarsi shorter than metatibiae. Abdomen in lateral view strongly convex.

Variation. Paratypes (14 males, 1 female) are similar to the holotype and allotype except in the following: Length 14.3–14.9 mm; width 8.0– 8.4 mm. Color: Pronotum yellowish brown with black vittae or entirely black, black areas frequently with a green hint. Head: Clypeus subquadrate to subrectangular. Male genitalia: Parameres as in Fig. 34c .

Diagnosis. This species is separated from other species in the group by the larger body size, clypeal declivity strongly developed, and form of the parameres.

Natural History. Nothing is known of its biology.

Temporal Distribution. November (14), December (3) ( Fig. 34d ).

Geographic Distribution. Known only from Nicaragua ( Fig. 34e ).

Etymology. This species is named for the country of origin ( Nicaragua) plus the Latin adjectival suffix “ ensis ” meaning “pertaining to, originating in”, together referring to being from Nicaragua.
