Abstract

Pleopeltis guttisquamata, a new epiphyte fern from the inselbergs of Espírito Santo, is described and illustrated. This new species belongs to the Pleopeltis squamata complex. Morphologically and geographically, P. guttisquamata most resembles P. hirsutissima s. str. and P. monoides, to which it is compared. We also present a key to all species of Pleopeltis occurring in the state of Espírito Santo, and a table containing the diagnostic characters of the members of the P. squamata complex in the region.

Morfologica e geograficamente, P. guttisquamata é próxima a P. hirsutissima s. str. e P. monoides, com as quais é comparada. Apresentam-se, também, uma chave de identificação para as espécies de Pleopeltis ocorrentes no estado do Espírito Santo, e uma tabela contendo os caracteres diagnósticos dos membros do complexo Pleopeltis squamata da região.
