Euphoria boliviensis Blanchard, 1850

(Appendix 4: Fig. 10 )

Euphoria boliviensis Blanchard 1850: 13 . Original combination.

Holotype at MNHN, examined.

Euphoria andina Schein 1950: 273 . Synonym.

Lectotype at MHNG here designated. Two paralectotypes at MHNG, examined.

Description (n = 30). Length 9.0– 11.4 mm; width 5.6–6.5 mm. Color: Surface shiny, black to brown. Pronotum black with greenish or reddish reflections, rarely with yellowish or whitish, cretaceous band on lateral margin. Elytra dark brown to reddish brown, with moderate to large, whitish to yellowish, cretaceous markings; markings globose, frequently covering elytra almost entirely. Pygidium frequently entirely covered by yellowish tomentum. Head: Frons moderately strigose, moderately densely to densely setose; setae moderate to long, whitish to yellowish. Clypeus subquadrate to subtrapezoidal, lateral margins weakly to moderately raised, subparallel, surface strongly to moderately strigose, moderately to densely setose; setae yellowish to whitish, moderate to long. Clypeal apex vaguely to weakly reflexed, apex truncate in dorsal view, weakly to moderately sinuate in frontal view. Antennal club as long as or longer than stem in males, shorter in females. Pronotum: Surface moderately densely punctate; punctures round to lunulate, moderate in size, denser and confluent towards sides and anterior margin, moderately to densely setose; setae moderate to long, yellowish to whitish. Scutellum longer than wide, weakly punctate; punctures bearing moderate to long setae. Base in front of scutellum strongly emarginate. Elytra: Surface sparsely to moderately densely punctate; punctures lunulate to irregularly lunulate, moderate in size, distributed in 2–3 irregular rows on striae, costae well defined. Posterior half of sutural costa raised in lateral view. Surface moderately to densely setose; setae moderate to long, whitish to yellowish. Legs: Protibial teeth well developed in both sexes, frequently sharp, apical tooth transverse or oblique, basal tooth well developed, apical and medial teeth closer to each than to basal tooth. Mesotibial carina well developed into 1–2 long spines, spines rarely reduced. Metatibial carina moderately developed. Metatibiae vaguely to weakly expanded apically, internal metatibial spur slightly thicker in females. Venter: Mesometasternal process extended to same level of mesocoxae or slightly beyond, apex rounded, flat, or slightly pointed, moderately densely to densely setose; setae long, yellowish. Mesepimera, metasternum, and metacoxae setose, setae as on legs. Metasternum rugose, setose laterally, glabrous, impunctate at middle. Median sulcus vaguely to weakly evident. Abdominal sternites sparsely punctate; punctures minute to small, moderately densely to densely setose laterally, glabrous to sparsely setose medially; setae moderate to long, whitish to yellowish. Abdomen in lateral view strongly convex in females, flat in males. Pygidium: Surface concentrically strigose, moderately densely to densely setose; setae short, yellowish. Male genitalia: Parameres as in Fig. 10c .

Diagnosis. Euphoria boliviensis is separated from other species in the group based on the setose mesometasternal process, mesotibial carina with well-developed spine, and elytra and pygidium frequently entirely cretaceous. This species is superficially similar to E. sonorae , but E. sonorae has the antennal club subequal in length in both sexes, and the elytra are densely punctate.

Taxonomic History. Blanchard (1850) described this species from Bolivia. Schein (1950), apparently unaware of Blanchard’ s earlier description, described Euphoria andina also from Bolivia (Cochabamba) and compared it with E. lurida .

Natural History. Adult specimens have been collected between 2,570–2,600 m elevation.

Temporal Distribution. January (2), March (1), April (4), November (5) ( Fig. 10e ).

Geographic Distribution. Known from the departments of Cochabamba, La Paz, and Santa Cruz in Bolivia ( Fig. 10f ).
