“…P. clarkii has been successfully introduced in all continents except Australia and Antarctica, e.g. it is recorded currently in 16 European countries (summarized in Gherardi, 2006;SoutyGrosset et al, 2016); and P. fallax f. virginalis established wild populations particularly in Germany (Chucholl et al, 2012), but it was also reported from Croatia (Samardžić et al, 2014), the Czech Republic (Patoka et al, 2016e), Hungary (Weiperth et al, 2015;Lőkkös et al, 2016), Italy (Nonnis Marzano et al, 2009;Vojkovská et al, 2014), the Netherlands (Koese, 2008), Slovakia (Jansk y and Mutkovič, 2010; Lipták et al, 2016), Sweden (Bohman et al, 2013), Ukraine (Novitsky and Son, 2016), and outside of Europe in Madagascar (Jones et al, 2009;Kawai et al, 2009). Though salinity tolerance in P. fallax f. virginalis seems to be low, it is much higher in P. clarkii (Vesel y et al, 2017 and references therein).…”

-The pet trade with decapod crustaceans has been considered one of the main pathway of introduction of these animals worldwide. As the leading markets in this regards are the Czech Republic, Germany and the USA. Central Asia is not perceived as an important market with ornamental decapod crustaceans. Despite this assumption, we found at least 16 species of freshwater shrimp, crayfish and crab species pet-traded in the Republic of Kazakhstan, the largest country in this region. Considering computed risk assessment, the origin of particular species, their availability on the market, the probability of establishment and further aspects, we identified two crayfish Procambarus clarkii and Procambarus fallax f. virginalis being the seriously hazardous taxa with high potential to threaten native crayfish species as well as inhabited ecosystems. To prevent their introductions and to minimize the risks of mentioned species, similarly as in the case of European Union, we recommend the total ban of import, trade and keeping of these high-risk taxa within Central Asia.

“…The animals were first described in the German aquarium trade in the late 1990s (Scholtz et al, 2003) and became widely distributed in subsequent years under their German name "Marmorkrebs". Stable populations have developed from anthropogenic releases in various countries including Madagascar, Germany, Czech Republic, Hungary, Croatia and Ukraine (Chucholl et al, 2012;Jones et al, 2009;Kawai et al, 2009;Liptak et al, 2016;Lokkos et al, 2016;Novitsky & Son, 2016;Patoka et al, 2016). On Madagascar, marbled crayfish form an aggressively expanding population that has invaded a large variety of habitats (Jones et al, 2009).…”

The marbled crayfish (Decapoda: Cambaridae) represents an independent new species

Marbled crayfish are a globally expanding population of parthenogenetically reproducing freshwater decapods. They are closely related to the sexually reproducing slough crayfish, Procambarus fallax, which is native to the southeastern United States. Previous studies have shown that marbled crayfish are morphologically very similar to P. fallax. However, different fitness traits, reproductive incompatibility and substantial genetic differences suggest that the marbled crayfish should be considered an independent species. This article provides its formal description and scientific name, Procambarus virginalis sp. nov.

“…This largest specimen was from a gravel pit in Reilingen, Germany (n=150; Lyko, 2017). Maximum CLs near 50 mm were determined in oligotrophic-mesotrophic thermal Lake Hévíz, Hungary (50.5 mm CL, n=42; Lőkkös et al, 2016), Lake Moosweiher, Germany (49 mm CL, n=496; this study, Chucholl & Pfeiffer, 2010;Günter, 2014;Lehninger, 2014;Wolf, 2014;Buri, 2015 From repeated collection in Lake Okeechobee (a eutrophic lake, Glades County, FL) a specimen was recorded at 42 mm CL (David Essian, FAU personal communication to N.J.D.) and specimens from other counties in Florida (e.g., Alachua County, collection of the USNM) measured up to 41 mm CL.…”

“…This criterion is fulfilled for marbled crayfish, since it can unambiguously be identified and distinguished from P. fallax by the easily measurable tri-allelic microsatellite PclG-02. In practice, COI was mostly used instead of PclG-02 to genetically identify marbled crayfish (e.g., Bohman et al, 2013;Lőkkös et al, 2016;Usio et al, 2017). However, strictly speaking, COI is not as specific as PclG-02.…”

The marbled crayfish is the only obligately parthenogenetic decapod crustacean and a novel research model and invasive animal on three continents. It is regarded either as a parthenogenetic form of slough crayfish Procambarus fallax or as a separate species named Procambarus virginalis. In order to investigate the species question of this unusual crayfish in detail we have identified the similarities and differences in morphology, life history, genetics, behaviour, ecology and biogeography between marbled crayfish and P. fallax. We have investigated specimens from natural habitats, laboratory colonies and museum collections and performed a meta-analysis of our data and published data. Our COI based molecular tree with 27 Cambaridae confirms closest relationship of marbled crayfish with P. fallax. Marbled crayfish and P. fallax are similar with respect to morphological characters, coloration and body proportions, but differ considerably with respect to body size, fertility and longevity.The mitochondrial genes of both crayfish are similar, but some nuclear genomic features are markedly different. Both crayfish are eurytopic and have two major annual recruitment periods, but marbled crayfish show different population structure and higher invasiveness.Marbled crayfish occur in boreal to tropical habitats of Europe, Madagascar and Japan, but Procambarus fallax is confined to the subtropics and tropics of the southeastern USA.2 Laboratory experiments suggest reproductive isolation of both crayfish. The application of the Evolutionary Genetic Species Concept for asexuals to all available data supports raising marbled crayfish from "forma" to species rank. A determination key is provided to discriminate Procambarus virginalis, the first asexual decapod species, from its most likely parent species P. fallax. depth comparison of major aspects of life between marbled crayfish and its presumed parent species P. fallax, going beyond the state of information presented in Vogt et al. (2015) and Lyko (2017). Of particular importance is the variability of morphological characters, life history traits and genetic markers in both crayfish, that was not sufficiently considered in previous papers. Therefore, in this study we have compared morphology, life history, genetics, behaviour, ecology and biogeography between both crayfish, using numerous specimens from wild populations, laboratory colonies and museum collections. Additionally, we have performed a meta-analysis of our data and the literature data. For marbled crayfish, almost 250 publications are known, mainly based on laboratory studies (references in Faulkes, 2018;Vogt, 2018a). The number of publications on P. fallax is less than 50 and most of them are on its ecology (references in Hobbs, 1981;Hendrix et al., 2000;VanArman, 2011;van der Heiden & Dorn, 2017;Manteuffel et al., 2018).In the Results section we describe the similarities and differences between marbled crayfish and P. fallax with respect to morphological traits, coloration, body proportions, body size, fertil...
