title: A new troglobitic species of Coarazuphium Gnaspini, Vanin & Godoy (Coleoptera, Carabidae, Zuphiini) from a cave in Paraná State, Southern Brazil.
abstract: A new troglobitic species of the Zuphiini genus Coarazuphium, C. ricardoi new species, is described on the basis of specimens collected inside the "Gruta do Varzeão" cave, in Paraná State. This is the first species of Coarazuphium described from Southern Brazil. The new species is compared with three other troglobitic species of the genus that are microphthalmous and have the elytral apical margins truncate (C. pains Álvares & Ferreira, C. tapiguassu Pellegrini & Ferreira and C. whiteheadi Ball & Shpeley). The most recent published keys for species identification of Coarazuphium are updated to include the new species.
