" The South American cyprinodontiform fish species with the vernacular name "mollies" are analyzed and three new species of the genus Poecilia are described and figured, viz., P. boesemani, n. sp. from Port of Spain, Trinidad, P. koperi, n. sp. from coastal areas of Venezuela and Colombia, and P. wandae, n. sp. from the Zulia district, Venezuela, west of Lake Maracaibo. Thirteen species of Poecilia are presently recognized from the northeastern part of South America and adjacent islands, viz., six mollies (including P. vivipara and P. caucana), five micropoeciliids, P. heterandria and the guppy (P. reticulata). Two different populations in both P. koperi and P. wandae are recognized, based on variation in pigmentation. From the type series of P. dovii Gunther, 1866 and P. vandepolli Van Lidth de Jeude, 1887 lectotypes are selected. Four subspecies of P. gillii are recognized as morphologically and geographically distinct populations.
Poecilia reticulata, P. heterandria, P. bifurca, P. parae, P. picta, P. branneri and P. minima are not considered herein, whereas P. laurae remains a species inquirendae. A geocline in characters of the species of Poecilia is recorded and an evolutionary scenario is discussed "
