Cryptic species are morphologically similar species that tend to be recognised as a single taxon. The genus Capsella contains two cryptic species, C. bursa-pastoris and C. rubella, which are sympatrically distributed on the Iberian Peninsula, but only one of them (C. bursa-pastoris) has been recognised as an introduced species in South America. In continental Chile, two specimens of C. rubella were collected from two distant sites, but it is unclear whether this indicates only local presence or a wider distribution. After extensive sampling throughout continental Chile, we analysed the diversity of collected Capsella specimens using molecular markers. Our aim was to establish the presence of C. bursa-pastoris and/or C. rubella in continental Chile. To this end, we used an amplification refractory mutation system (ARMS) to detect the trnD–trnY fragment of cpDNA, which allowed the differential amplification of polymorphic sites for both species. A subsample of these amplification products (n = 8 fragments) was sequenced and compared with previously documented sequences for C. bursa-pastoris and C. rubella. Of 188 plants, 96.8% were identified as C. bursa-pastoris and 3.2% as C. rubella. C. bursa-pastoris was collected at all localities (28°34ʹS–53°09ʹS), whereas C. rubella was collected only in central-south Chile (34°59ʹS–41°28ʹS). This confirms that both C. bursa-pastoris and C. rubella are present in continental Chile, although they apparently exhibit different abundances and ranges. Our results suggest efforts to elucidate distribution of both Capsella species in South America.

AbstractRecently, the number of cryptic species known has increased considerably, showing that species diversity has in many cases been underestimated in the past. Parmelia sulcata is a widely distributed species and one of the most common taxa in temperate Europe. The first intra-specific molecular studies on P. sulcata showed an unexpectedly high genetic variability. In the present work, we study the biodiversity of this taxon including specimens from four continents and using three molecular markers (nuITS, nuIGS rDNA, and partial β-tubulin gene). Two monophyletic groups of P. sulcata were encountered; one of these is epitypified as P. sulcata s. str and the other one is segregated as the new cryptic species P. encryptata sp. nov. Issues surrounding the lectotypification of Parmelia sulcata have also been elucidated.

AbstractCryptic species can present a significant challenge to the application of systematic and biogeographic principles, especially if they are invasive or transmit parasites or pathogens. Detecting 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. In asexual or self-fertilizing species, the latter criteria are of limited use. We studied a group of cryptic freshwater snails (genusGalba)from the family Lymnaeidae that have invaded almost all continents, reproducing mainly by self-fertilization and transmitting liver flukes to humans and livestock. We aim to clarify the systematics, distribution and phylogenetic relationships of these species with an integrative approach that includes morphology (shell and reproductive anatomy), molecular markers, wide-scale sampling across America, and data retrieved from GenBank (to include Old World samples). Our phylogenetic analysis suggests that the genusGalbaoriginated ca. 22 Myr ago and today comprises six clusters of species. Four of these clusters (G.truncatula,G.cubensis/viator,G.humilisandG.schirazensis) are morphologically cryptic and constitute species or species complexes with wide variation in their genetic diversity, geographic distribution and invasiveness. The other two clusters constitute a single species or a species complex (Galba cousini/meridensis) that demonstrate more geographically restricted distributions and exhibit an alternative morphology more phylogenetically derived than the cryptic one. Further genetic studies are required to clarify the status of bothG. cousini/meridensisandG.cubensis/viator. We emphasize that noGalbaspecies should be identified without molecular markers and that additional sampling is required, especially in North America, Eurasia and Africa to clarify remaining questions in systematics and biogeography. We also discuss several hypotheses that can explain crypsis inGalba, such as convergence and morphological stasis, and hypothesize a role for stabilizing selection in amphibious (rather than strictly freshwater) habitats.
