Fig. 5 in Jenynsia luxata, a new species from Northwestern Argentina, with additional observations of J. maculata Regan and phylogeny of the genus (Cyprinodontiformes: Anablepidae)
Fig. 5. Topologies from most equally parsimonious trees and relative Bremer support/GC values under (a) equal weights (strict consensus of 12 trees), and (b) implied weighting (strict consensus of two trees), with concavities K = 4 to 20 (with supports measured under K = 8). Unsupported nodes are shown as collapsed. The relationships of genera of the family are consistent with those proposed in previous studies, therefore species of Anableps and Oxyzygonectes are not shown.
