THE FAMILY COMPSOPOGONACEAE (RHODOPHYTA) IN BRAZIL

Abstract

A taxonomic revision of the family Compsopogonaceae in Brazil was carried out, resulting in the recognition of a single genus (Compsopogon) with two species (C. coeruleus and C. leptoclados). For both species the following information was provided: a) nomenclatural type; b) type locality; c) description (with illustrations); d) diagnostic features; e) world distribution; f) distribution in Brazil (with map); g) habitat, associated species and seasonality; h) remarks, including discussion of taxonomic and/or nomenclatural problems and comparison with previous reports based on Brazilian and foreign material. Currently accepted diagnostic criteria for genera and species within Compsopogonaceae are critically analysed. The circumscription of Compsopogon and Compsopogonopsis are evaluated and the single genus Compsopogon is recognized in the family.
