The species Atyaephyra desmarestii (Millet, 1831) has a wide geographic distribution in freshwater habitats, rivers and lakes, spanning from North Africa to the Middle East, a large part of Europe and some Mediterranean islands. This wide distribution, together with the disjunct nature of freshwater populations, makes A. desmarestii a candidate taxon to undergo processes of cryptic speciation. To test this assumption, in the present study two mitochondrial genes (16S and COI) were used to examine the diversity between selected populations across the distribution range of this species. The data support three clearly distinguishable groups of haplotypes. The largest one includes the majority of the west European populations and the North African ones, belonging to Atyaephyra desmarestii desmarestii. Within this group the genetic composition found for the Portuguese specimens does not support the validity of Atyaephyra rosiana de Brito Capello, 1867 as a different species, and is therefore here proposed to represent a synonym of Atyaephyra desmarestii. The second European group includes two Greek populations which must be considered as a different species and are tentatively identified as Atyaephyra stankoi (Karaman, 1972) according to geographic distribution. This species-level distinction is supported by high genetic differences, although morphological differentiation is not clear at present. The third group comprises only one sequence from Iraq whose value of genetic variability for 16S could support A. mesopotamica Al-Adhub (or A. orientalis Bouvier) as a valid species. Unfortunately, there are no COI sequences available for this specimen that could be used to confirm its status.

Endemic atyids of southern Europe have been ascribed to Dugastella, and to subterranean Typhlatya and Troglocaris: Dugastella is epigean, and Typhlatya and Troglocaris are subterranean. An extensive collection from all centres of distribution in southern Europe (excepting the Caucasus) was morphologically examined. A taxonomic redefinition of the group, at different levels, is based on recently published and newly generated molecular phylogeny, whereas newly established taxa have also been morphologically defined. The accordance between the phylogenetic tree and the geographical distributions suggested that a re-evaluation of some traditionally used morphological characters should generate the most parsimonious solution: this enabled a novel taxonomic division. Gallocaris gen. nov. is erected for the French Troglocaris inermis Fage, 1937, which is more closely related to the epigean Dugastella valentina (Ferrer Galdiano, 1924) than to its supposed congeners. Both western Mediterranean Typhlatya species are closely related to their Caribbean congeners. All other European cave shrimps constitute a monophylum, Troglocaris, which is divisible into subgenera (already with available names): the holo-Dinaric Troglocaris (Troglocaris) Dormitzer, 1853, south-eastern mero-Dinaric Troglocaris (Troglocaridella) Babi{\'c}, 1922, and Troglocaris (Spelaeocaris) Matja\ši{\v c}, 1956, and the Caucasian Troglocaris (Xiphocaridinella) Sadovsky, 1930. Four new species are described: Troglocaris (Troglocaris) bosnica sp. nov., Troglocaris (Spelaeocaris) prasence sp. nov., Troglocaris (Spelaeocaris) kapelana sp. nov., and Troglocaris (Spelaeocaris) neglecta sp. nov. The distribution of all established species is shown, and the value of the morphological characters is discussed.

The alien crustaceans Atyaephyra desmarestii (Millet, 1831) and Jaera istri Veuille, 1979 were recorded for the first time in the territory of the Czech Republic. Atyaephyra desmarestii was found in May 2007 in the River Elbe near Lib{\v e}chov and Jaera istri was found in August 2008 in the River Elbe at D{\v e}{\v c}\ín. Only a single specimen of Atyaephyra desmarestii was collected, while Jaera istri was found in tens of specimens and was the most numerous aquatic invertebrate on site.
