Description. The carapace has an elongated shape and is set with a maximum of four large tubercles. The tubercles as well as the space between them are covered with a more or less pronounced but distinct wide-sized mesh pattern. The hinge margin is almost straight, passing smoothly onto the rounded anterior border with an obtuse angle. The transition onto the posterior border forms a ledge through the posterior “hinge ear”. Both borders merge smoothly with the ventral margin, which is medially depressed. Both the anterior-and posterior margins can contain a number of irregular distributed small sized tubercles. The marginal zone is broadly developed and is hosting a number of spaced, straight running pore canals. Dimension: Male: l = 0,60 – 0,62 mm, h = 0,3- 0,32 mm; Female: l = 0,55- 0,60 mm; h = 0, 26 – 0,31 mm.

Ecology. L. multituberculata has been mentioned by Grossi et al. (2015) as part of a “ Cyprideis- Loxoconchidae assemblage”, representing low mesohaline and shallow water conditions. Living representatives of the species were described by Gofman (1966) and Yassini (1986) from the central and southern Caspian Basins at salinities of 11.5 – 18.25‰.
