The turbulent and intricate geology of the Mediterranean region has been responsible for connections, redirections, and interruptions of freshwater systems that have been instrumental in the speciation and distribution of many organisms, including freshwater shrimps. There are 50 species and subspecies currently reported from the freshwater systems of the broader Mediterranean region that belong to 11 genera and three families. Three of these are exotic species that have been introduced to the region\’s ecosystems from elsewhere. The majority of species of Mediterranean freshwater shrimps belong to the Atyidae, followed by the Palaemonidae, and the Typhlocarididae, and most species have a very restricted distributional range. Among the three Mediterranean Peninsulas, the Balkan Peninsula fosters the highest biodiversity and is the species hotspot within the region. Subterranean (hypogean) and surface (epigean) habitats of the broader Mediterranean region are equally dwelled by shrimps. Currently 14 native species of freshwater shrimps are assessed by the IUCN Red List as threatened with extinction from increased freshwater ecosystem degradation which underlines the urgent need for conservation action.

We describe the sexual dimorphism in the genus Atyaephyrade Brito Capello, 1867 (family Atyidae De Haan, 1849) through the example of A. thyamisensisChristodoulou, Antoniou, Magoulas \& Koukouras, 2012 as a contribution to the ongoing effort to describe the morphological variability in the genus. Individuals of A. thyamisensis were collected from Thyamis River (Epirus, northwestern Greece) over a period of five years. Selected characters were examined on the basis of already known differences recorded from the literature and from direct observations in order to detect possible intersexual morphological differences in this species. A total of 42 somatometric distances and 14 meristic characters were measured. The morphological comparison as well as the statistical analysis showed a clear separation between the two sexes and between non-ovigerous and ovigerous females. Besides the first and second pair of pleopods, sex-related differences were found between the third and fourth pair of pereiopods, rostrum, carapace, antennules, and chelae, whereas differences between the non-ovigerous and ovigerous females were most obvious in the abdominal segments. Also discussed are the key sexual morphological characters that can aid in distinguishing the species of Atyaephyra

In order to elucidate the distinction of Atyaephyra desmarestii subspecies (A. d. desmarestii, A. d. orientalis, A. d. stankoi and A. d. mesopotamica) and investigate their geographical distribution in Greece, the main morphological features and somatometric ratios were studied in numerous specimens collected from a dense station network of Greek fresh waters. Specimens from Belgium, Portugal, Albania and Turkey were also examined. Atyaephyra desmarestii was found in western and northern Greece while it was absent in eastern Greece, the Aegean and the Ionian islands. The comparison of the obtained data with those of the literature revealed a clearly overlapping variability of the main key morphological features among the four subspecies. The results of this study indicate that the current A. desmarestii subspecies are not valid on the basis of the used key features. There is only one very variable species with many ecophenotypes.

The freshwater shrimp, Atyaephyra desmarestii (Millet, 1831) is redescribed on the basis of a topotypical population (Toulouse). Its original description by Millet (1831) is very short and inadequate. Concerning populations from the same area, no further descriptive information has been actually given. Specimens studied from a Belgian population (Ombret) did not show any important differences from the French ones.

The freshwater shrimp, Atyaephyra rosiana De Brito Capello, 1867 is redescribed on the basis of a population (Algarve, Portugal) close to the topotypical area and a neotype is designated for this species. Its original description by De Brito Capello (1867) is very short and inadequate. A detailed comparison of the neotypes of A. rosiana and Atyaephyra desmarestii (Millet, 1831) revealed the presence of key morphological features that clearly distinguish these species from each other.\

A complete serial of larval staging of Atyaephyra desmarestii (Millet, 1831) sensu lato from Louros River (north-western Greece) was obtained in the laboratory and described in detail. Thirty berried females were collected and transferred to an aquarium containing water and vegetation from the sampling site. The newly hatched larvae were transferred into small sterile aquaria and mass cultured. After each moult, several larvae were photographed and preserved with their exuviae. The reared larvae of A. desmarestii sensu lato passed through six zoeal stages and one megalopal stage. At the experimental conditions, the durations of each larval stage were as follows: three days for the 1st larval stage; three to four days for 2nd larval stage; six to eight days for 3rd; seven to nine days for 4th; nine to ten days for 5th, 6th and megalopal stages. All the obtained stages were described in detail. The larval morphological characters of the described material and the larvae specimens collected from natural populations were compared with the literature data on closely related species. Morphological description of the different phases for juveniles, immature, female and male mature individuals of A. desmarestii sensu lato are also presented in detail.
