Nomenclatural comments. After the examination of the type specimens of Diponthus cribratus (Serville) and D. clarazianus Pictet & Saussure , and based on the information provided in the original descriptions and on the examined material from the distribution area of the species, we consider both nominal species actually constitute a single specific entity, being D. clarazianus the junior synonym.

Diagnosis. Pronotal disc with a median dorsal longitudinal yellow band; prozona with two oblique yellow bands extending up to the median sulcus; metazona black mottled ( Figs. 3c, d View FIGURE 3 , and 7a, b View FIGURE 7 ). Prosternal tubercle laterally compressed, apex directed backwards. Tegmina with irregular transverse veins yellow colored, delimiting large cells with blackish central spots ( Fig. 8e View FIGURE 8 ). Hind wings with yellow or tan background, with black spots. Male cerci short, not surpassing the tip of epiproct, slightly down-curved (straight dorsally and with a slight concavity ventrally) ( Fig. 9a View FIGURE 9 ). Epiproct subovoidal with acute apex; tubercles on distal half; furculae small ( Fig. 9b View FIGURE 9 ). Dorsal valves of aedeagus moderately thin, basal two thirds straight with the apex slightly down-curved ( Fig. 10e View FIGURE 10 ). Valves of cingulum placed perpendicular to the dorsal valves of aedeagus (in dorsal view), rod-shaped ( Fig. 11e View FIGURE 11 ). Cingulum opened U-shaped; zygoma wide, anterior margin straight with rounded antero-lateral edges ( Fig. 11e View FIGURE 11 ). Epiphallus with lophi placed parallel to bridge, widely expanded towards the posterior processes of the lateral plates ( Fig. 12a View FIGURE 12 ); superior edges oblique in frontal view ( Fig. 12b View FIGURE 12 ).

Redescription and chromatic characters, and material examined. See Appendix 1

Measurements (in mm). Body length: males: 40.3 (40–41); females: 50.3 (47–53) from fastigium to end of abdomen, 42 (41–43) from fastigium to apex of tegmina. Hind femur length: males: 18 (17–19); females 22.6 (22–24). Tegmina length: males: 26.3 (23–30); females: 28.6 (28–29).

Distribution. This species is found in Argentina (Entre Ríos, Buenos Aires) and Uruguay (Río Negro, Tacuarembó, Montevideo) ( Fig. 13 View FIGURE 13 ).
