Previous issue date: 2001 / CAPES / Uma hipótese filogenética baseada em 173 caracteres é proposta para peixes poecilioideos. A
análise incluiu caracteres de osteologia e morfologia externa, resultando em uma única árvore
mais parcimoniosa com 607 passos, índice de consistência 36 e índice de retenção 72. Foi
obtida a seguinte topologia: (Jenynsia multidentata ((Aplocheilichthys spilauchen
(Procatopus nototaenia (Lamprichthys tanganicus (Micropanchax lamberti (Micropanchax
johnstoni (Congopanchax myersi (Hylopanchax stictopleuron + Fluviphylax simplex)))))))
(Tomeurus gracilis (Gambusia nicaraguensis (ALfaro huberi (Priapella compressa
(Brachyrhaphys cascajalensis (Heterandria bimaculata + Priapichthys annectens)))))
(Neoheterandria tridentiger ((Girardinus serripenis + Xenodexia ctenolepis) (Phallichthys
fairweatheri (Xiphophorus helleri (Poecilia heterandria ((Limia pauciradiata (Poecilia
vivipara (Poecilia sphenops + Poecilia velifera))) ((Micropoecilia parae + Lebistes
reticulatus) (Pamphorichthys hollandi (Poeciliopsis prolifica (Phallotorynus jucundus
(Cnesterodon carnegiei (Phalloceros caudimaculatus (Phalloptychus januarius))))))))))))))))).
É proposta uma nova classificação, na qual Poeciliidae e Procatopodidae assumem status de
família, formando um clado corroborado por 17 caracteres morfológicos apomórficos.
Relacionamentos de grupo irmão entre Tomeurus e os poeciliideos remanescentes, suportados
em revisões clássicas, ficam aqui confirmados. Poeciliinae é restrito a duas tribos, Gambusiini
and Poeciliini, com modificações na composição e na posição filogenética dos membros
incluídos. / 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 topology was obtained: (Jenynsia multidentata ((Aplocheilichthys
spilauchen (Procatopus nototaenia (Lamprichthys tanganicus (Micropanchax lamberti
(Micropanchax johnstoni (Congopanchax myersi (Hylopanchax stictopleuron + Fluviphylax
simplex))))))) (Tomeurus gracilis (Gambusia nicaraguensis (Alfaro huberi (Priapella
compressa (Brachyrhaphys cascajalensis (Heterandria bimaculata + Priapichthys
annectens))))) (Neoheterandria tridentiger ((Girardinus serripenis + Xenodexia ctenolepis)
(Phallichthys fairweatheri (Xiphophorus helleri (Poecilia heterandria ((Limia pauciradiata
(Poecilia vivipara (Poecilia sphenops + Poecilia velifera))) ((Micropoecilia parae + Lebistes
reticulatus) (Pamphorichthys hollandi (Poeciliopsis prolifica (Phallotorynus jucundus
(Cnesterodon carnegiei (Phalloceros caudimaculatus (Phalloptychus januarius))))))))))))))))).
A new classification is proposed, in which Poeciliidae and Procatopodidae assume family
status, forming a clade corroborated by 17 apomorphyc morphological characters. Sistergroup
relationships between Tomeurus and the remaining poeciliids, as supported in previous
classical revisionary studies, is herein confirmed. Poeciliinae is restricted to two tribes,
Gambusiini and Poeciliini, with modifications in composition and phylogenetic position of
included members.
