Distribution

The species is distributed in an area between the Adriatic and Black Seas, including the Dinaric Alps ( Jäch and Skale 2015).

Remarks

The taxonomy of this species of the " Haenydra " lineage is not yet finally resolved. Three slightly varying morphs are recognised. Our specimens (Fig. 3 E, F) belong morphologically and geographically to "Morph A" sensu Jäch and Díaz (2012). The standard DNA barcode of this morph which we are providing herein varies, in fact, by 0.5% from "Morph B" (Bulgaria).

Habitat

All specimens were collected from moderately fast flowing, shallow water, but on varying substrates, including submerged wood, grass bunches and pebble.
