Kryptolebiasinae. This is a clade composed by a single genus with seven valid non-annual species, distributed in theAtlantic coastal basins and estuaries from Florida ( USA) to southern Brazil. Three androdioecius species conform a monophyletic unit within the genus ( Vermeulen, Hrbek, 2005; Costa et al., 2010) that inhabit mangroves; two of them with clear evidence of self-fertilization ( Tatarenkov et al., 2011). Costa (2004) proposed two synapomorphies for Kryptolebias : a dorsally expanded flange on dorsal tip of the autopalatine ( Fig. 1a) and a vestigial or absent anterodorsal process of urohyal ( Fig. 2a).
