title: New species of Aplectana (Ascaridida: Cosmocercidae) in the toads, Rhinella granulosa and Rhinella schneideri (Anura: Bufonidae) from northern Argentina.
abstract: Aplectana adaechevarriae n. sp., from the large intestine of Rhinella granulosa and Rhinella schneideri, is described and illustrated. Of the 43 nominal species of Aplectana, A. adaechevarriae n. sp. represents the 23rd Neotropical species and the third species reported from Argentina. Of the Neotropical species, only 4, Aplectana elenae, Aplectana hylambatis, Aplectana raillieti, and A. adaechevarriae n. sp., have 8 pairs of preanal papillae. Aplectana adaechevarriae lacks a median preanal papilla; the other 3 species possess a median preanal papilla.
