Diagnosis. Distinguishable from superficially similar specimens of Axina munda by the configuration of the dark elytral markings. In A. vista specimens the 2 posterior dark markings are transverse, whereas in A. munda specimens these markings are punctiform. Also, there are considerable differences when comparing their aedeagi (compare Fig. 39 , 52 ).

Description. Size. Length 6.8 mm; width 2.0 mm. Form. As in Fig. 110 . Color. Testaceous, except mesofemora and metafemora infuscated distally, and each elytron with three dark brown markings, one punctiform marking at humeral angle, one transverse marking just behind middle and at elytral apical 3/4. Head. Cranium finely punctate, frons wider than length of antennal pedicel; EW/FW 37/12. Thorax. Pronotum finely punctate, with 2 tumescences, concave at middle; PW/PL 80/110; elytra, asetiferous punctures striate, punctures extend to slightly beyond elytral middle, interstitial spaces vary in width; EL/EW 310/55. Abdomen. Aedeagus ( Fig. 39 ), phallobasic lobes very long narrow, approximate; phallic apical region produced, margin of phallic plates copiously serrate; phallobasic apodeme abbreviated.

Variation. Size: Length 6.0–11.0 mm; width 1.4–2.5 mm. The brown markings on the elytral disc vary in prominence. The middle pair may be absent, and the posterior pair may be in the form of transverse fasciae. In general, these markings may be only faintly visible.

Natural history. Specimens were collected in Bolivia during October, November, December, and February, some at elevations that range from 370–1,350 m. Others were collected in Peru during October, November, February, and March, some at 290 m. Brazilian specimens were captured during October.

Distribution (for map see Fig. 71 ). This species is known from Bolivia, Peru, and Brazil.

Etymology. The specific epithet, vista , is a noun in apposition and refers to the type locality.

ochra species group

There are two members in this species group whose specimens are characterized by an extended phallic apex. Their distribution involves Venezuela, Bolivia, and Brazil.
