included four characters: 1) female with prominent, well sclerotized, solenostomes arching anteriorly from the antero- median corner of the ventral opisthosomal suckers (64.2); 2) male with long, recurved, and largely smooth spermatodactyl (7.2); 3) male lacking prominent spines on legs II (107–110); 4) adults lacking spine-like marginal opisthosomal setae (77). Of these, characters 1and 2, while unique, are not shared by some taxa included in the genus in this study (e.g., population Alabama-C). As a result, the diagnosis (and support) for this genus is not strong. Data on additional species may help clarify the concept of this genus.
