Phylogenetic hypotheses of Typhlatya spp. from the Yucatán Peninsula. (A) Multi-gene (16S rRNA, COI, CYTB, 18S rRNA, 28S rRNA, H3) phylogeny of select Typhlatya spp. sequences, Bayesian phenogram shown; (B) 16S rRNA phylogeny of GenBank and sampling new to this study, Bayesian phenogram shown; (C) Graphical summary of phylogenetic relationships from previous studies21,22,30,31. Support values indicated at nodes above branches: Bootstrap/Bayesian Posterior Probability. Supports values < 90/0.90, not shown (see text) and indicated by ‘–’. Colors represent species identity resulting from the molecular evaluations of this study (A–C): Typhlatya pearsei = yellow, Typhlatya mitchelli = red, Typhlatya dzilamensis = blue, Typhlatya sp. A purple, Typhlatya sp. B orange. Filled black shapes beside species’ identifications (B) indicate previous identifications of GenBank material in conflict with the present study: circle = Typhlatya sp., triangle = T. pearsei, square = T. mitchelli. Shapes beside species’ identifications (C) indicate species identifications from previous work: circle = Typhlatya sp., triangle = T. pearsei, square = T. mitchelli, star = T. dzilamensis. Sequences from specimens collected from type localities indicated by colored stars (A,B): green star = T. campecheae, Grutas de Xtacumbilxunam; blue star = T. dzilamensis, Dzilam de Bravo. Sequences from samples with known salinity (in psu) are indicated by colored water droplets (B), blue = low salinity, 0.5–4.99, red = high salinity, 5–37.
