“…Pardosa groenlandica, one of the species that was widely sampled in this study, and with high intraspecifi c divergence value (max =3.87%), may also represent a species complex but may not be completely cryptic. Dondale (1999) reached the same conclusion after observing signifi cant geographical variety in the epigynal ratio (length: width ratio of the sclerotized region covering the internal female genitalia) within P. groenlandica, suggesting the need for further investigation of this morphospecies.…”

In: Stoev P, Dunlop J, Lazarov S (Eds) A life caught in a spider's web. Papers in arachnology in honour of Christo Abstract While previous research has indicated the utility of DNA barcoding in identifying spider species sampled from a localized region, the eff ectiveness of this method over a broader geographic scale and with denser taxon sampling has not yet been extensively considered. Using both new and published data from 1801 individuals belonging to 361 morphospecies, this study examined intra-and interspecifi c divergences for 19 genera that were each represented by at least 10 morphospecies. We particularly focused on increasing species-level sampling in order to better characterize levels of interspecifi c divergence within species-rich genera and to examine the prevalence of a "barcode gap" (discontinuity between intra-and interspecifi c divergences). Overall, the mean intraspecifi c divergence value was found to be 2.15%, the average maximum intraspecifi c divergence was 3.16%, while the mean divergence between nearest interspecifi c neighbours was 6.77%, demonstrating the typical presence of a barcode gap. Of the 66% of morphospecies that formed monophyletic sequence clusters, the majority (92.5%) possessed a barcode gap. We also examine possible biological explanations for the large proportion of paraphyletic and polyphyletic clusters and discuss the need for further taxonomic investigations. Th e overlap between intra-and interspecifi c divergences was not unexpected for some 'species', such as Pardosa groenlandica, since prior morphological studies have suggested that it is an example of a species complex. However, other cases of high intraspecifi c divergences may refl ect cryptic species diversity, indicating the need for a taxonomic approach that combines both morphological and molecular methods. Th e list of the species, COI sequences, and source references used in the analysis is published as a dataset under doi: 10.3897/zookeys.16.239.app.A.ds. Th e list of analyzed species, mean and maximum intraspecifi c divergences, distances to the nearest neighbouring species in its genus, general localities, and lifestyle characteristics is published as a dataset under doi: 10.3897/zookeys.16.239.app.B.ds.

“…With regard to North American species of Pardosa, studies have focused on Pardosa falcifera F.O.P.-Cambridge 1902 and P. zionis Chamberlin & Ivie 1942 (Vogel 1970) and P. dromaea (Thorell 1878) and P. groenlandica Thorell 1872) (Dondale & Redner 1990;Dondale 1999). In Japan, Suwa (1980Suwa ( , 1984 and Tanaka & Suwa (1986) studied the ethological differences among closely related species in the P. laura Karsch 1879 complex.…”

Abstract. The study of courtship behavior provides a useful tool for identifying cryptic species due to the qualitative differences that can be observed in closely related species. Here, we present an overview of visual courtship displays of 26 European species of the genus Pardosa C.L. Koch 1847, including new quantitative and qualitative data. Thirty-five recurring courtship elements are described and illustrated by means of drawings, photos and videos (available online). In general terms, complex movements of the palps, the first pair of legs and the abdomen characterize courtship displays in the genus Pardosa. The most complex movements are performed by the palps, while legs and abdomen mainly oscillate in the air or vibrate on the substrate. We noticed a high level of complexity in almost all of the species, both in terms of sensory modes involved and number of courtship elements composing the displays. No apparent relationships emerged when considering ethological similarities among species, attesting to the relative independence between morphological and ethological characters.

“…Additionally, they all share similar geographical ranges, being found across the northern hemisphere from Iceland west to Russia above 32u latitude; each is sympatric with at least one other member of the species complex in a portion of its range. All seven are listed as valid species by Platnick (2013) based on the morphological taxonomic work of Kronestedt (1975), , Dondale (1999) and Vogel (2004). The species group is part of the modica group of Pardosa, one of the most speciose genera of wolf spiders, and five of the members had been previously revised as a subgroup by Dondale (1999).…”

The species group is part of the modica group of Pardosa, one of the most speciose genera of wolf spiders, and five of the members had been previously revised as a subgroup by Dondale (1999). Because of these attributes, these species make an excellent group to test the reliability of identifications made using only morphological diagnostic characters.…”
