( Figures 19a–e )

Podalgus rubripes Boheman 1858: 57 (original combination).

Ligyrus guianucai Dechambre and Lumaret 1985: 107 (New Synonymy).

Tomarus rubripes was described from, supposedly, Montivideo, Uruguay, although this simply may have been a port-of-call for the frigate Eugenie on which the specimens were transported back to Sweden. The male holotype is in NHRS, and we examined multiple images, including the parameres. In our examination of numerous collections holding Tomarus specimens from the study area, we have never seen specimens of T. rubripes from Uruguay or Argentina, although we have seen specimens from Brazil. We have no definitive evidence that T. rubripes occurs in the study area.

Tomarus guianucai was described by Dechambre and Lumaret (1985) from Cassino Beach, Rio Grande do Sul, Brazil; this locality is adjacent to Uruguay. Examination of the types of both species reveals that they are conspecific, and T. guianucai is here reduced to junior synonymy with T. rubripes . Dechambre and Lumaret made no mention of examining the type of T. rubripes when they described T. guianucai and so did not recognize the similarities between the two.
