abstract (from publication):
The genus Rhamdella is considered to be composed of six species but only R. aymarae and R. cainguae have been recorded from Argentina. Information on the distributions of these species is scarce and R. cainguae is only known from its type locality. This note documents a wider distribution range of R. cainguae and reports R. longiuscula in Argentina for the first time.
