Subgenera Bessopora THOMSON 1859 and Podoxya MULSANT & REY 1875

Bessopora (type species: O. testacea ERICHSON 1837 ) and Podoxya (type species: O. lentula ERICHSON 1837 ) currently include various species groups; the subgenera are poorly defined and undoubtedly not monophyletic. The characters traditionally used to distinguish them from other subgenera and from each other (relative length of antennomere III, length of elytra, shape of abdomen, density of abdominal punctation, shape of antenna, absence of derived characters) (e.g., BERNHAUER 1902) are either of unknown polarity or primitive. Many of the species currently attributed to either of the two subgenera are intermediate in one or several characters. Therefore, the following species, which would have to be assigned to either Bessopora or Podoxya , are treated as species incertae sedis.
