The Neotropical species of Notalina, a southern group of long‐horned caddisflies (Trichoptera: Leptoceridae)

The leptocerid trichopteran genus Notalina is recorded from the South American continent for the first time. Seven new species are described in it and placed in a new subgenus, Neonotalina: N.brasiliana, N.morsei, N.cipo and N.hamiltoni from southeastern Brazil, comprise the brasiliana species‐group, and N.roraima from Venezuela, N.nanay from Peru and N.matthiasi from Colombia form the roraima species‐group. Notalina (Neonotalina) is identifiable by the presence of a long, slender baso‐mesal process on the male inferior appendage. The two species‐groups may be distinguished by the morphology of the male phallus. The historical biogeography of the genus in South America is discussed.
