Description (n = 37). Length 13.5–16.7 mm; width 8.0– 10.3 mm. Color: Dorsal surface tomentous or shiny, yellowish brown, reddish brown, orangish brown, or dark brown. Pronotum frequently with 2 longitudinal, irregular, dark vittae covering most of or entire surface, vittae frequently divided basally, appearing as 4 vittae. Elytra with black or dark green markings variably covering surface. Ventral surface, including legs, light brown to black. Pygidium frequently with 2 whitish, longitudinal, cretaceous markings. Head: Frons frequently slightly raised at middle, densely punctate; punctures deep, moderate to large, frequently confluent, moderately densely to densely setose; setae long to moderate, whitish to yellowish. Clypeus short, surface as on frons, sides moderately to strongly arcuate, moderately raised in males, vaguely to weakly raised in females; apex truncate in dorsal view, moderately reflexed in males, weakly reflexed in females. Antennal club as long as stem in males, shorter in females. Pronotum: Surface moderately densely punctate; punctures lunulate, small to moderate, sparsely to densely setose; setae short to moderate, yellowish. Sides near base frequently convergent in males, subparallel in females. Base in front of scutellum strongly emarginate. Scutellum impunctate. Elytra: Surface moderately densely punctate, striae bearing 3 rows of small, lunulate punctures and/or short grooves, sparsely to moderately densely setose, setae short to moderate. Costae evident to weak. Apex and sides posteriorly weakly rugose. Pygidium: Surface subconcentrically striate, striae discontinuous, sparsely to moderately densely setose; setae minute to short, yellowish. Legs: Protibiae slender in males, robust in females, apical and medial teeth strongly proximal, basal tooth frequently obsolete in males. Mesotibial carina weakly developed. Metatibiae not apically expanded in males, moderately expanded in females; metatarsi as long as or longer than metatibiae in males, shorter in females. Venter: Mesometasternal process extending anteriorly well beyond mesocoxae, weakly constricted at middle, apex variable rounded, setose on mesosternal lobe. Metasternum rugose, setose laterally, glabrous and impunctate at middle, median sulcus weakly impressed. Sternites sparsely setose medially, moderately setose laterally, setae moderate in length. Abdomen in lateral view flat to weakly concave in males, weakly convex in females. Male genitalia: Parameres as in Fig. 26c View Fig .
Diagnosis. This species is separated from other species in the group by the arcuate sides of the clypeus, setose mesosternal lobe of the mesometasternal process, strongly proximal apical and medial protibial teeth, pronotal and elytral punctation, and form of the parameres. This is the only species in the group known from South America.
Notes. The misspelled version “ Euphoria abronea ” was first found in Blackwelder (1944) and more recently in Hardy (2001).
Taxonomic History. Janson (1878) described E. abreona from a brownish male specimen from Bogotá, Colombia. Janson (1881) described an additional shiny, greenish black male from Quito, Ecuador as E. morosa , and a tomentous, dark olivegreen male from “ New Granada ” as E. precaria . Bates (1889) listed E. morosa as affined to E. chontalensis .
Both E. morosa and E. precaria correspond to color forms of E. abreona , and all three can occur at one location. I collected a large series of this species close to Los Santos, Santander, Colombia, where all three color forms were present (i. e., Orozco and Pardo-Locarno 2004). Based on this occurrence, examination of key characters, and study of the types, I place both E. morosa and E. precaria in synonymy with E. abreona .
Natural History. Adults are known to be attracted to fruit traps baited with rotten plantains. The third instar and pupa were described by Orozco and Pardo-Locarno (2004).
