Corrigendum to "Pushing barcodes to their limits: phylogenetic placement of Fontigens Pilsbry, 1933 (Caenogastropoda: Littorinimorpha: Truncatelloidea) and elevation of Fontigentidae Taylor, 1966

Abstract

Molecular phylogenetics revolutionized the systematics of the megadiverse ‘hydrobioid’ gastropods (i.e. Hydrobiidae sensu lato Davis, 1979) by showing them to be a polyphyletic group within the superfamilies Rissooidea Gray, 1847 and Truncatelloidea Gray, 1840 (Wilke et al. , 2001; Criscione & 2013). Wilke et al. (2013) revealed extensive morphological homoplasy in the hydrobioids and emphasized the need to use molecular data for higher- level classification. This facilitated numerous taxonomic revisions, most of which serve as the current basis of freshwater rissooidean and truncatelloidean taxonomy (Bouchet et al. , 2017; MolluscaBase, 2021a, b). Molecular data have also been integral to recent species descriptions and population-level analyses of hydrobioids (Wilke & Davis, 2000; Haase, 2008; Delicado, Machordom & Ramos, 2012; Osikowski et al. , 2017). However, newly available sequence data have not been synthesized to clarify the still uncertain family-level systematics of some hydrobioids. One such unresolved taxon is the subfamily Fontigentinae which consists only of the Fontigens Pilsbry,
