Diagnosis.

According to the original description and Young (1986), this species has the clypeus thickened but not margined, the pronotum has punctation similar to the head, the pronotal plicae extend about 1/3 distance across pronotum, the apex of the prosternal process is truncate, not acuminate, the prosternum and prosternal process are not carinate or spinous, and the last abdominal ventrite is not modified.

Discussion.

The holotype is a female ( Young 1986). Young (1986) was unable to identify this species, but thought it close to Bidessodes semistriatus and Bidessodes knischi , but also thought Bidessodes acharistus may represent the species.

Distribution.

Only known from the type locality in Paraguay (Fig. 103).
