“…Present along the Caspian Sea shores, in the Volga River, and the Sea of Azov. Lived until the late 1980s in the Aral Sea but is possibly extinct there now (Andreev et al 1992, Aladin et al 1998, Micklin et al 2014). …”

Defining and recording the loss of species diversity is a daunting task, especially if identities of species under threat are not fully resolved. An example is the Pontocaspian biota. The mostly endemic invertebrate faunas that evolved in the Black Sea – Caspian Sea – Aral Sea region and live under variable salinity conditions are undergoing strong change, yet within several groups species boundaries are not well established. Collection efforts in the past decade have failed to produce living material of various species groups whose taxonomic status is unclear. This lack of data precludes an integrated taxonomic assessment to clarify species identities and estimate species richness of Pontocaspian biota combining morphological, ecological, genetic, and distribution data. In this paper, we present an expert-working list of Pontocaspian and invasive mollusc species associated to Pontocaspian habitats. This list is based on published and unpublished data on morphology, ecology, anatomy, and molecular biology. It allows us to (1) document Pontocaspian mollusc species, (2) make species richness estimates, and (3) identify and discuss taxonomic uncertainties. The endemic Pontocaspian mollusc species richness is estimated between 55 and 99 species, but there are several groups that may harbour cryptic species. Even though the conservation status of most of the species is not assessed or data deficient, our observations point to deterioration for many of the Pontocaspian species.

“…However, it was restricted to the southern part of the sea (Andreev & Andreeva, 1988). Harris mud crab was still recorded in the 1980s when the sea underwent a strong regression, increased salinity (about 30 g l −1 ) and separation into the Large and the Small Aral salt lakes (Andreev et al , 1992; Aladin et al , 2004). Desiccation of the Large Aral continued and apparently R. harrisi has not survived the phase of increasing salinity up to 57 g l −1 .…”

“…The Small Aral is maintaining lower salinity (now 8–11 g l −1 ) owing to the Syr-Daria River discharge (Izhitskiy et al , 2016). It seems that the Harris mud crab had failed to reach the Small Aral before its separation in 1989 (Andreev et al , 1992). In the expeditions of IO RAS in 2014 (Izhitskiy et al , 2016) and 2015 the coastal areas of the Small Aral near village of Akbasty (46°16.5′N 60°54.7′E) was surveyed specifically for R. harrisii , however there have been no sightings.…”

A survey of publications and collections databases reveals a pattern of non-indigenous decapods distribution in the 13 seas around Russia and adjacent countries. No alien species were reported from Russian territorial waters and exclusive economic zone in the Japan, Okhotsk, west Bering and most of the Siberian shelf Seas. From the seas and their basins in East Europe, 13 alien species have been recorded, with seven of these yet to become established. Established or commonly occurring species can be categorized as: ‘global invaders’ (Chinese mitten crab,Eriocheir sinensisin the White, Baltic, Black, Azov and Caspian Seas; and Harris mud crab,Rhithropanopeus harrisiiin all mentioned seas, except the White Sea); ‘regional aliens’ (Palaemon adspersusandP. elegansin the Caspian Sea and the latter species in the Baltic); and ‘Arctic invaders’ (Kamchatka king crabParalithodes camtschaticusand snow crabChionoecetes opilio).Eriocheir sinensisis the most widely occurring alien decapod species, but there are no indications of an established population in East Europe. For this and other mentioned crab species, invasion history, distribution and important biological data are reviewed. In the seas where few or no native crab species have been present, Harris mud crab (in the Azov and Caspian Seas), Kamchatka crab (in the Barents Sea) and snow crab (in the Barents and Kara Seas) have shown rapid establishment (within two decades) of an invasive population throughout an entire basis or its significant part.

“…We propose this species to be classified as LC. While the species has incurred a reduction of range given regional extirpation in the Aral Sea (Andreev et al 1992;Aladin et al 1998;Micklin et al 2014), it still occupies a very large distribution range and is common within the Caspian and Azov drainage basins. Moreover, it has expanded into man-made channels between the Volga and Don rivers (personal observation A.F.S.…”

“…Theodoxus major is found in the Caspian Sea and parts of the Azov Sea (Roth 1987, Karpinsky 2002Anistratenko et al 2017;Sands et al 2019a) and is also present in the Volga and Don river systems (Sands et al 2019b). It has likely become regionally extinct in the Aral Sea (Andreev et al 1992;Aladin et al 1998;Plotnikov et al 2016), although it may still persist in some of its associated drainages (Zettler 2007). In Western Asia it can be found in the Aras River system (Aliyev and Ahmadi 2010), Lake Yerevan and its catchment systems in Armenia (Sands et al 2019b), and Masalli in Azerbaijan.…”

Asia contains a high species diversity of the freshwater gastropod genus Theodoxus. Recent molecular and morphological reviews of this diversity have uncovered a number of yet undescribed species while suggesting the urgent revision of several others. Moreover, some of these studies have indicated a number of species previously not recorded for this continent. Despite the advancements, a taxonomic revision and an update on the distribution of Theodoxus spp. in Asia is still pending. Here, we construct the most robust phylogeny of Theodoxus up to now and review original descriptions, type material, recent taxonomic revisions, compendia, and species lists to provide a comprehensive checklist of all known extant Asian Theodoxus spp. Our checklist also provides descriptions for three recently discovered and yet undescribed species (Theodoxus gurur Sands & Glöer, sp. nov., Theodoxus wesselinghi Sands & Glöer, sp. nov., and Theodoxus wilkei Sands & Glöer, sp. nov.), as well as shows the need to synonymise several previously described morphospecies. The present revision recognizes 14 extant Theodoxus spp. for Asia. Some of these species are widespread, while others are endemic to just a single location. Based on the revised and new distribution data, we provide updates and new assessments of species conservation statuses.
