Oncochelyna barrigai (SOLERVICENS, 2004) (Figs 15, 41, 71, 91)

Exochonotus barrigai SOLERVICENS 2004: 31.

Holotype: ♂. ARGENTINA, Prov. Córdoba, Cruz del Eje, I feb 1998, leg. J. E. Barriga (MNNC). Allotype: Same locality as the holotype (MNNC). Paratype: one specimen from Argentina, Provincia de Santiago del Estero, Añatuya (JEBC). OPITZ 2017a: 73.

Diagnosis: The unicolorous characteristic (castaneous) of the elytral disc will distinguish these beetles from O. tuberculata.

Description: This species was adequately described and illustrated by SOLERVICENS (2004: 31). Additional characteristics involve: Antenna as in Fig. 15, pronotum as in Fig. 41, elytral asetiferous punctation striate, elytral 2° setae prominent, epipleural margin serrulate at elytral distal 1/4 th, and habitus as in Fig. 91.

Variation: Size: Length 4.0-5.0 mm; width 1.3-2.0 mm. Other than body size, the available specimens were quite homogeneous.

Distribution (Fig.71): In addition to the holotype and allotype, I examined 2 specimens from: Argentina: Provincia de Tucumản, Departamento de Burruyacủ, 7 de Abril, 14-27-I-1981, R. Golbach. Specimens are deposited in IMLA, JEBC, MNNC, and WOPC.
