Description (n = 116). Length 14.9–20.5 mm; width 8.5–11.9 mm. Color: Dorsal surface entirely or partially tomentous, bright green, dark green, or violaceous. Pronotum shiny in females, tomentous in males. Elytra with small, sparse, irregular, whitish, cretaceous spots. Ventral surface shiny, color as on dorsum. Head: Frons densely punctate; punctures small to moderate, round, deeply impressed, at times coalescent; surface depressed, with 1 central or 2 longitudinal depressions separated by ridge; sparsely to moderately setose; setae short to moderate, yellowish. Clypeal surface moderately densely to densely punctate; punctures moderate in size, round; clypeus short, lateral margins moderately to strongly raised, sides moderately convergent at apex; lateral declivity weakly to moderately developed; apex strongly reflexed, strongly sinuate in frontal view, occasionally giving appearance of 2 small denticles; glabrous to moderately densely setose; setae yellowish to whitish, short to moderate. Vertex flattened. Antennal club as long as or slightly shorter than stem in males, shorter than stem in females. Antennal club in males shorter than head in lateral view. Pronotum: Surface sparsely to moderately densely punctate; punctures round to lunulate, minute to moderate, denser and larger towards sides, more evident in females than in males, glabrous to sparsely setose, setae minute to short, yellowish, limited to anterolateral angles. Pronotal sides moderately to weakly angulate, females frequently with subparallel sides at base, males generally with convergent sides at base. Base in front of scutellum moderately to strongly emarginate. Scutellum longer than wide, impunctate. Elytra: Surface glabrous, sparsely punctate; punctures minute, costae obsolete to subobsolete. Posterior half of sutural costa strongly raised in lateral view. Pygidium: Surface subconcentrically striate, striae discontinuous, dense, moderately to strongly impressed, sparsely to moderately densely setose; setae minute to short, yellowish. Legs: Protibial teeth well developed, equidistant or apical and medial tooth slightly closer to each other than to basal teeth. Meso- and metatibial carinae weakly to moderately developed. Metatarsi compressed in females, much shorter than metatibiae; metatarsi slender, about as long as metatibiae in males. Metatibial spurs long and slender in males, shorter and frequently thicker in females. Venter: Mesometasternal process extended anteriorly well beyond mesocoxae, process glabrous on mesosternal lobe, apex variably rounded. Mesepimera, metasternum, and metacoxae setose, setae as on legs. Metasternum rugose, setose laterally, glabrous, impunctate at middle. Median sulcus strongly impressed. Abdominal sternites moderately densely setose laterally, glabrous to sparsely setose medially, sides rounded. In lateral view male abdomen flat to vaguely concave, female abdomen flat to vaguely convex. Male genitalia: Parameres as in Fig. 23c .

Diagnosis. Euphoria lesueuri is separated from other species in the group by the flat vertex, antennal club of the males shorter than the head in lateral view, pronotal vestiture sexually dimorphic (tomentous in males ( Fig. 23a, d ), shiny in females ( Fig. 23e ), and form of the parameres.

Taxonomic History. Gory and Percheron (1833) described this species three times under different names, all based on Mexican specimens. Euphoria lesueuri was based on a female, E. latreillei on a male, and E. notulata on a reddish specimen. Burmeister (1842) recognized E. lesueuri and E. latreillei as valid species and placed E. notulata in synonymy with E. lesueuri . Harold (1869) recognized E. lesueuri and E. latreillei as valid species and treated E. notulata as a synonym of E. latreillei . Bates (1889) commented on Sallé finding E. latreillei and E. lesueuri in copula and consequently treated E. latreillei as a synonym of E. lesueuri .

Natural History. Adults of E. lesueuri have been collected in fruit traps, hanging plantains, and at lights. Adults have also been collected on Asteraceae .

Temporal Distribution. April (17), May (37), June (18), July (7), August (1), September (2) ( Fig. 23f ).

Geographic Distribution. Known from Oaxaca, Mexico to Nicaragua ( Fig. 23g ). Morón et al. (1997) recorded this species from Puebla. I treat this record as suspect given the difficulties in identifying this species before this monograph.
