  abstract = {{C}ryptic species can present a significant challenge to the application of systematic and biogeographic principles, especially if they are invasive or transmit parasites or pathogens. {D}etecting cryptic species requires a pluralistic approach in which molecular markers facilitate the detection of coherent taxonomic units that can then be analyzed using various traits (e.g., internal morphology) and crosses. {I}n asexual or self-fertilizing species, the latter criteria are of limited use. {W}e studied a group of cryptic freshwater snails (genus {G}alba) from the family {L}ymnaeidae that have invaded almost all continents, reproducing mainly by self-fertilization and transmitting liver flukes to humans and livestock. {W}e aim to clarify the systematics, distribution, and phylogeny of these species with an integrative approach that includes morphology, molecular markers, wide-scale sampling across {A}merica, and data retrieved from {G}en{B}ank (to include {O}ld {W}orld samples). {O}ur phylogenetic analysis suggests that the genus {G}alba originated ca. 22 {M}yr ago and today comprises six species or species complexes. {F}our of them show an elongated-shell cryptic phenotype and exhibit wide variation in their genetic diversity, geographic distribution, and invasiveness. {T}he remaining two species have more geographically restricted distributions and exhibit a globose-shell cryptic phenotype, most likely phylogenetically derived from the elongated one. {W}e emphasize that no {G}alba species should be identified without molecular markers. {W}e also discuss several hypotheses that can explain the origin of cryptic species in {G}alba, such as convergence and morphological stasis.},
