Maximum-likelihood phylogeny and species delimitations of Stygobromus anacostensis and other S. tenuis species group taxa for the mtDNA dataset (co1+16s loci). Asterisk represents bootstrap node support greater than 90. Colored bars represented hypothesized MOTU groupings (i.e., species) based on corresponding delimitation analyses.
