Pelonium tuberculata PIC 1935: 101.

Lectotype: ♀. Argentina, Chaco de Santiago de Estero ( MNHN). CORPORAAL 1950: 290 (Corinthiscus). SOLERVICENS 1998: 79 (Exochonotus); 2004: 31 (Exochonotus); 2006: 23 (Exochonotus).

Diagnosis: The infuscations on the elytral disc will distinguish these beetles from O. barrigai.

Head: Cranium coarsely punctate, antennal funicular antennomeres subquadrate ( Fig. 16 View Figs 1-27 ), capitulum lax, antennomeres 9 and 10 triangular, antennomere 11 ovate; eyes small, frons wide (EW/FW 10/25); last maxillary and labial palpomere securiform. Thorax: Pronotum ( Fig. 42 View Figs 28-43 ) with angular tubercle at sides, disc coarsely punctate, without knobs; elytral asetiferous punctures arranged into 10 punctiform striae, punctures binodal, punctures extend to elytral apex, entire length of epipleural margin serrulate. Abdomen: Aedeagus short, distal region of phallobase slightly lobed, tegmen very reduced, submembranous, phallobasic struts confluent with phallobasic apodeme, phallobasic rod long; phallic plates broad, phallic apex small triangular.
