SYNONYMS: None. REMARKS: See Pavan and Voss (2016) for a diagnosis of this morphologically distinctive taxon. Subgeneric monophyly is strongly supported by phylogenetic analyses of the multilocus sequence datasets reported by Pavan et al. (2014 , 2016) and by Bayesian analysis of the dataset reported by Vilela et al (2015) . Nine species are currently recognized, but several of these are difficult to distinguish morphologically, and identifications of unsequenced specimens are correspondingly problematic.
