The taxonomy of the common guppy, Poecilia reticulata Peters, 1859, is reviewed and the closely related Campoma guppy, P. wingei n. sp., is described. Formerly, the common guppy was not judged to be closely related to any other species of Poecilia, but the new species is the second species to be allocated in the subgenus Acanthophacelus Eigenmann, 1907. The recognition of P. wingei results from observed character displacement, i.e., on the interaction between two closely related species in a… 
Description of Poecilia (Acanthophacelus) obscura n. sp., (Teleostei: Poeciliidae), a new guppy species from western Trinidad, with remarks on P. wingei and the status of the "Endler's guppy"
A mitochondrial DNA-sequence based molecular phylogenetic analysis revealed the status of the new species as a separate taxon, Poecilia obscura, which is described from the Oropuche system, Trinidad and can be distinguished by morphometrics and gonopodial characteristics from these two species, although the ranges for all values overlap.
The evolution of placentas and superfetation in the fish genus Poecilia (Cyprinodontiformes: Poeciliidae: subgenera Micropoecilia and Acanthophacelus)
This study describes the life histories of six species within the genus Poecilia that includes the subgenera Micropoecilia and Acanthophacelus and demonstrates that extensive placentotrophy and superfetation, the ability to simultaneously carry more than one developing brood, have evolved within this clade.
Morphological Study to Improve Identification Toward Poeciliidae Family Based on Gonopodium Structures and Morphometric Analysis
The research is aimed at identifing the species of Peciliidae fishes living in Lake Sari, Pasuruan, based on gonopodium structures and morphometric analysis.
First record of the non-native fish Poecilia reticulata (Cyprinodontiformes: Poeciliidae), in Chiapas, southern Mexico
The neotropical fish Poecilia reticulata, found in México in 1971, has extended its range to the Grijalva Usumacinta river system.
Morphological Study for Identification Improvement of Poeciliidae Family Based on Gonopodium structures and Morphometric analysis
This research is aimed to identify the species of Peciliidae fishes which lives in Sari Lake Pasuruan based on gonopodium structures and morphometric analysis.
A New Species of Poecilia from Honduras (Teleostei: Poeciliidae)
Poecilia hondurensis, new species, differs from all congeners in the combination of having tricuspid teeth on the inner of both jaws and lacking a prominent spine or hook on the gonopodium.
Population structure of guppies in north-eastern Venezuela, the area of putative incipient speciation
The authors' findings are consistent with only partial genetic isolation between the two geographic regions and indicate that the geographic barrier of Cordillera de la Costa has not played an important role in strengthening the incomplete pre-zygotic reproductive barrier between Cumaná and common guppy.

The ever-increasing global trade of ornamental aquarium fishes is one of the most important pathways for aquatic invasion. Occurrence of ornamental freshwater fishes in natural freshwaters has been


Phylogenetic analysis of the tribe Poeciliini (Cyprinodontiformes: Poeciliidae)
I follow Parenti's (1981) use of Poeciliinae, which is a group of freshwater fishes known only from the New World that includes Fluviphylacinae and Aplocheilichthyinae that is diagnosable by the presence of a copulatory gonopodium in the male.
Character Displacement and Coexistence in Two Poeciliid Fishes of the Genus Poecilia (Mollienesia) from Hispaniola
Character displacement in animals, particularly in fishes, is reviewed and the new approach of Grant (1975) is used in this study to demonstrate character displacement in P. hispaniolana and P.
Phylogenetic relationships among the mollies (Poeciliidae: Poecilia: Mollienesia group) based on mitochondrial DNA sequences
All members of Molliensia form a monophyletic group, which supports the more traditional taxonomy and classification of these species as comprising the subgenus Mollienesia as proposed previously and revealed several interesting relationships.
Nonrandom variation in Poecilia marcellinoi n. sp. and P. salvatoris Regan, 1907 in El Salvador (Pisces, Poeciliidae)
A new species of the genus Poecilia Bloch & Schneider, 1801 is recorded from El Salvador and a high degree of character displacement is observed in populations from stable freshwater habitats, in habitats with presumed marine influences.
Molecular phylogeny of the live-bearing fish genus Poecilia (Cyprinodontiformes: Poeciliidae).
The complete NADH Dehydrogenase Subunit 2 (ND2) mitochondrial gene is sequenced in representatives of the major divisions of the genus Poecilia in order to examine the phylogenetic relationships within the genus.
The role of character displacement in the speciation of Central American members of the genus Poecilia (Poeciliidae)
The application of a peculiar mode of character displacement to two species of fish from El Salvador suggests a general mechanism that explains much of the morphological variation within the Central American members of Poecilia.
Life-History Evolution in Guppies (Poecilia reticulata: Poeciliidae). IV. Parallelism in Life-History Phenotypes
The life-history phenotypes of guppies from the north slope communities are compared and it is found that the high- and low-predation contrasts are remarkably similar to those reported earlier for the south slope communities.
Life-History Evolution in Guppies (Poecilia reticulata: Poeciliidae). V. Genetic Basis of Parallelism in Life Histories
A combination of the geographical breadth of the first study and the greater depth of this study provides a more complete picture of interpopulation variation in guppy life-history patterns.
Experimentally Induced Morphological Diversity in Trinidadian Guppies (Poecilia reticulata)
Morphological differences in males between the floating and bottom feeders correspond, respectively, to open water (fusiform) and benthic (deeper-bodied) forms described both among and within many fish species.
Sexual isolation and extreme morphological divergence in the Cumaná guppy: a possible case of incipient speciation
It is suggested that divergent sexual selection has contributed to differentiation of the Cumaná guppy, and this may be the first example of incipient speciation in the guppy.
