Adacna laeviuscula ( Eichwald, 1829)
( Fig. 4 View Fig : 1).
1986 Adacna (Adacna) laeviuscula (Eichwald, 1831) . – Yakhimovich et al.: 85, pl. 11, fig. 8.
2013 Adacna laeviuscula ( Eichwald, 1829) . – Bogutskaya et al.: 377, fig. 154, photo 48.
Dimensions – max. L 32 mm, H 21 mm.
Characterization – Large, subquadrate to subtrigonal thinshelled flat cardiid with strong posterior and slight anterior gape; dorsal margins relatively straight; relatively few ribs that are thin in juvenile stages and become very flat and separated by barely perceptible grooves in adult stages; hinge is a mostly edentulous, straight and flat ridge; in juvenile specimens a small cardinal tooth may be present that disappears in adult stages.
Ecology – This species has been listed from the entire CS from water depths between 35 and 100 m in salinities of at least 4 psu ( Bogutskaya et al., 2013; Logvinenko and Starobogatov, 1969). The common occurrence of fresh, paired specimens on exposed beaches of the middle Caspian (Turali, Russia; Sirvan, Azerbaijan: pers. observ. FW) demonstrates that A. laeviuscula has viable populations in foreshore settings above storm wave base indicating shallower habitats than previously reported.
