Species

The genus contains at least one valid species:

Dia patagonica Boheman, 1858, also from Chile, was placed in the genus by Jan Bechyné in 1953, but as the type is apparently lost or destroyed, this species is considered incertae sedis in Eumolpinae by Askevold & LeSage (1990).[2]

Several additional species were described in or assigned to the genus by Jan Bechyné from other countries in South America, though these may not belong to the genus according to Askevold & LeSage (1990):[2]

  • Jansonius boggianii (Jacoby, 1899) – Paraguay, Argentina
  • Jansonius pubescens Bechyné, 1955 – Paraguay
  • Jansonius scolytinus Bechyné & Bechyné, 1961[5] – Brazil
  • Jansonius vigiensis Bechyné & Bechyné, 1961[6] – Brazil
