Revisão da hipótese de monofiletismo da família Aplocheilidae, Bleeker (Cyprinodontiformes - Aplocheiloidei)
The hypothesis of monophyly and inter relationships of the family Aplocheilidae are reexamined. The analysis is based on morphology, primarily osteology, of 25 species. It includes 130 characters, of which 34 are new; 30 are personal communications by Costa and the remaining are from Parenti's …

Filogenia e classificação dos peixes poecilióideos (Cyprinodontiformes: Cyprinodontoidei)
A phylogenetic hypothesis based on 173 characters of 34 taxa is proposed for poecilioid fishes. The analysis included characters of osteology and external morphology and resulted in a single most parsimonious tree with with 607 steps, consistency index 36 and retention index 72. The following …
