Description. Holotype male. Length 11.4 mm; width 6.5 mm. Color: Dorsal surface reddish brown, mostly tomentous, partially shiny. Pronotal anterior margin shiny, tomentous elsewhere, with 2 longitudinal, regular, dark green vittae on each side of midline and 1 small, dark, semicircular, anterolateral marking on each side. Elytral apex and sides shiny, tomentous elsewhere, with dark green, irregular markings. Ventral surface, including legs, dark brown. Head: Frons slightly raised at middle, densely punctate; punctures deep, moderate in size, confluent, sparsely setose; setae yellowish, moderate in size. Clypeus subquadrate, slightly subtrapezoidal, laterally expanded anteriorly in dorsal view, lateral margins moderately raised; apex weakly reflexed, moderately sinuate; punctation as on frons, sparsely setose; setae yellowish, short to moderate. Antennal club as long as stem. Pronotum: Surface moderately densely punctate; punctures round, small to moderate, denser and larger toward apex, sparsely setose; setae minute on sides, yellowish. Sides moderately angulate. Apex with small swelling. Midline and base impunctate. Base in front of scutellum weakly emarginate. Scutellum impunctate, apex sharp. Elytra: Surface moderately densely punctate; striae bearing 2 densely punctate lateral rows of lunulate punctures, irregular punctures, and grooves and 1 sparsely punctate medial row of lunulate punctures; punctures small to moderate, glabrous to sparsely setose; setae minute to short, whitish to yellowish; apex and sides weakly rugose. Pygidium: Surface subconcentrically striate;striae dense,discontinuous, moderately densely setose, setae short to moderate. Apex broadly, evenly rounded. Legs: Apical and medial protibial teeth closer to each other than to basal tooth. Meso- and metatibial carinae moderately developed. Metatibiae not expanded apically, metatarsi longer than metatibiae. Venter: Mesometasternal process moderately compressed laterally, extending anteriorly to same level as mesocoxae, apex truncate. Mesepimera, metasternum, metepimera, and metacoxae setose, setae as on legs. Metasternum rugose, moderately to densely setose laterally, sparsely punctate and setose at middle, median sulcus strongly impressed. Abdomen in lateral view flat.

Allotype. Female. Similar to holotype except in the following: Length 12.5 mm; width 7.2 mm. Color: Elytra entirely dark green, almost black. Head: Frons sparsely setose. Clypeus subquadrate, sides weakly raised, apex not reflexed. Antennal club shorter than stem. Pronotum: Base in front of scutellum moderately emarginate. Pygidium: Apex slightly pointed. Legs: Protibial teeth strongly developed. Meso- and metatibial carinae strongly developed. Metatibiae moderately expanded apically. Metatarsi shorter than metatibiae. Abdomen in lateral view strongly convex.

Variation. Paratypes (29) similar to the holotype and allotype except in the following: Length 10.9–12.7 mm; width 6.1–7.2 mm. Color: Surface dark brown to yellowish brown. Pronotal vittae occasionally reduced to absent. Elytral markings occasionally reduced to absent. Melanistic forms present. Head: Frons sparsely to moderately densely setose. Pronotum: Midline punctate to impunctate. Base in front of scutellum weakly to moderately emarginate. Elytra: Surface sparsely setose, setae minute to short. Legs: Protibiae slender in males, robust in females, basal tooth frequently obsolete to subobsolete in males, apical and medial teeth proximal in males; teeth equidistant and well developed in females. Meso- and metatibial carinae weakly to moderately developed in males, moderately to strongly developed in females. Male genitalia: Parameres as in Fig. 48c .

Diagnosis. This species is separated from other species in the group by the following combination of characters: clypeus subquadrate; scutellum impunctate; elytral striae with irregular grooves; pygidial apex sexually dimorphic in shape (round in males, pointed in females); and form of the parameres.

Natural History. Adults have been collected in fruit traps baited with mango and watermelon, and have been captured at 290 m elevation.

Temporal Distribution. July (36), September (1) ( Fig. 48d ).

Geographic Distribution. Known from Jalisco, Mexico ( Fig. 48e ).

Etymology. The specific epithet is from the Latin vittata , meaning “with vittae”, referring to the dark pronotal markings of this species.
