Name
Plesiolebias Costa, 1989
Plesiolebias is a genus of fish in the family Rivulidae. These annual killifish are endemic to seasonal pools, swamps and lagoons in the Araguaia–Tocantins, Xingu, and uppermost Paraguay (Pantanal) river basins in Brazil.[2]
They are small fish, up to 5 cm (2.0 in) in total length.[3] As typical of killifish, males are more colorful than females.[2]
Species
Plesiolebias and the closely related Maratecoara, Papiliolebias, Pituna and Stenolebias form a clade, Plesiolebiasini.[2]
There are currently eight recognized species in Plesiolebias:[3]
Plesiolebias altamira W. J. E. M. Costa & D. T. B. Nielsen, 2007
Plesiolebias aruana (Lazara, 1991)
Plesiolebias canabravensis W. J. E. M. Costa & D. T. B. Nielsen, 2007
Plesiolebias filamentosus W. J. E. M. Costa & G. C. Brasil, 2007
Plesiolebias fragilis W. J. E. M. Costa, 2007
Plesiolebias glaucopterus (W. J. E. M. Costa & Lacerda, 1989)
Plesiolebias lacerdai W. J. E. M. Costa, 1989
Plesiolebias xavantei (W. J. E. M. Costa, Lacerda & Tanizaki, 1988)
