Halacarellus hyrcanus (Viets, 1928)

Syns.: Caspihalacarus hyrcanus Viets, 1928 , Caspihalacarus hyrcanus danubialis Motas & Soarec- Tanasachi, 1943

Records associated with decapod crustaceans – This species was found setae-covered claws of Chinese mitten crab Eriocheir sinensis from Germany ( Normant et al. 2013). This species

(reported as variety of Caspihalacarus hyrcanus danubialis Motas & Sorec ) was found in association with amphipod crustaceans Corophium and Dikerogammarus (cf. Green & MacQuitty 1987).

Other records – This species was reported from Caspian Sea, Black Sea, and rivers flowing to Black Sea. The majority of findings are from river. This species most likely inhabits unsorted sediments, well aerated and rich in organic matters ( Bartsch 2006a); epibenthic in and on sediment amongst roots of vascular plants, green algae and tubes of an associated fauna (Bartsch 1979; Martens et al. 2006; Bartsch and Gerecke 2011). This species was also reported from Isparta, Lake Eğirdir at about 910 m a.s.l. on sediments and stones ( Durucan 2020).

Remarks – This species was recorded from freshwater to salinity 12.5‰. Caspihalacarus hyrcanus Viets, 1928 moved to Halacarellus as H. hyrcanus (Viets, 1928) by Bartsch & Gerecke (2011).
