Abstract
The Hygrobatidae family includes, inter alia, two closely related genera Atractides Koch, 1836 and Hygrobates Koch, 1837. They are widespread and associated mainly with running waters. The genera differ substantially in species diversity, at least as it may be estimated by morphological features, with the genus Atractides being much richer in species than Hygrobates. These differences, in the number of species, are all the more puzzling as the genus with a wider environmental distribution contains fewer species. Species of the genus Atractides are almost exclusively rheobiotic and reophilic or, occasionally crenophilic, while Hygrobates inhabit not only running waters and springs, but also standing waters. In the light of recent molecular studies, the species diversity of Hygrobates has increased by 9 species (H. arenarius Smit & Pešić, 2017, H. corsicus Pešić & Smit, 2017, H. marezaensis Pešić & Dabert, 2017, H. persicus , H. turcicus, H. balcanicus, H. mediterraneus, H. ulii and H. grabowskii) in the complex Hygrobates fluviatilis; by two (H. limnocrenicus and H. lacrimae) in the Hygrobates nigromaculatus complex and by one (H. prosiliens) in the Hygrobates longipalpis complex. Apart from the species complexes mentioned above, two new species were detected with the use of DNA barcoding method. They are currently being described. Species diversity is clearly related to geographical diversity, therefore it can be suspected that there will be even more cryptic or pseudo-cryptic species in the Hygrobates genus. This confirms the legitimacy of further research in this matter.
