Description. Holotype male. Length 10.8 mm; width 6.3 mm. Color: Dorsal surface yellowish brown, tomentous, elytral sides and apex shiny. Pronotum yellowish brown, with 2 longitudinal, regular, black vittae at each side of midline, midline reddish; 1 small, dark, semicircular, anterolateral mark on each side. Elytra with small, black, irregular markings. Ventral surface, including legs, light to dark brown. Head: Frons slightly raised basally at middle, densely punctate; punctures deep, moderate in size, confluent, moderately densely setose; setae yellowish, moderate in size. Clypeus subrectangular, sides weakly raised, apex laterally expanded in dorsal view, moderately sinuate, not raised; punctation as on frons, moderately densely setose; setae yellowish, short to moderate. Antennal club longer than stem. Pronotum: Surface moderately densely punctate; punctures lunulate, small to moderate, denser and larger toward apex, midline and base mostly impunctate, moderately densely setose; setae short to moderate, yellowish. Apex with small swelling at center. Sides moderately angulate. Base in front of scutellum weakly emarginate. Scutellum impunctate, apex sharp. Elytra: Surface moderately densely punctate, striae bearing 2 moderately dense lateral rows of punctures and 1 sparsely punctate medial row; punctures small to moderate, lunulate to irregular; apex and posterior end of sides weakly rugose, glabrous to sparsely setose; setae minute to short, whitish to yellowish. Pygidium: Surface subconcentrically striate; striae dense, discontinuous, densely setose, setae short to moderate. Apex rounded. Legs: Protibiae slender, apical and medial teeth proximal, basal tooth obsolete. Meso- and metatibial carinae moderately developed. Metatibiae not expanded apically, metatarsi as long as metatibiae. Venter: Mesometasternal process small, moderately compressed laterally, extending anteriorly slightly beyond mesocoxae. Mesepimera, metasternum, metepimera, and metacoxae setose, setae as on legs. Metasternum rugose, moderately to densely setose laterally, weakly punctate and setose at middle, median sulcus strongly impressed. Abdomen in lateral view flat.

Allotype. Female. Similar to holotype except in the following: Length 11.1 mm; width 6.3 mm. Color: Pronotal surface shiny on apex and sides, vittae covering the surface entirely except at base. Ventral surface, including legs, mostly dark brown. Pygidium lightly colored at apex. Head: Frons sparsely setose. Clypeus slightly subtrapezoidal, sparsely setose, apex weakly sinuate. Antennal club shorter than stem. Pronotum: Base in front of scutellum weakly emarginate. Pygidium: Apex slightly pointed. Legs: Protibiae robust, teeth equidistant, well developed. Meso- and metatibial carinae strongly developed. Metatarsi shorter than metatibiae. Abdomen in lateral view strongly convex.

Variation. Paratypes (16) similar to the holotype and allotype except in the following: Length 8.6–11.5 mm; width 4.8–6.2 mm. Color: Pronotal vittae variably extending over midline and lateral margins. Male genitalia: Parameres as in Fig. 46c .

Diagnosis. This species is separated from other species in the group by the following combination of characters: small size; clypeus subrectangular to subtrapezoidal; pronotal apex with small swelling at center; mesometasternal process small, moderately compressed laterally; apex of pygidium sexually dimorphic in shape and color (round and monochromatic in males, weakly pointed and with lightly colored areas in females); and form of the parameres. Males of this species can be difficult to separate from those of E. quadricollis , but the parameres are shorter in E. montana than in E. quadricolli s. Euphoria quadricollis is a sexually dimorphic species in body size and coloration (males small and tomentous, females large and shiny). There is no sexual dimorphism of this type in E. montana .

Natural History. Part of the type series was collected on Rubus sp. above 1,900 m elevation. Otherwise, nothing is known about its biology.

Temporal Distribution. August (13), September (23) ( Fig. 46d ).

Geographic Distribution. Known from Sinaloa and Durango, Mexico ( Fig. 46e ).

Etymology. From the Latin montanus meaning “from the mountains”. All specimens in the type series were collected above 1,900 m.
