70. Euglesa subtruncata ( Malm, 1855)

Findings in Serbia.

Pisidium subtruncatum: Tomović et al. (2010 b) ; Tomović et al. (2014).

Common name. Short-ended pea mussel

Morphology. Minute bivalve. The shell typically is up to 4 mm in length, 3 mm in height, and 2.5 mm in depth. For more details see Welter-Schultes (2012: 23, figure on the top of the page).

Distribution and ecology. Holarctic species inhabiting a muddy and sandy substrate of free-flowing waters (though it could be found in various standing waters as well). In Serbia, it was recorded in the Danube.

Other remarks. Shell morphology is fairly variable. This is one of the most frequent and dominant Pisidium species in streams and small rivers, where it often coexists with P. nitidum Jenyns, 1832 . A total of 34 nominal species are known as synonyms ( Graf & Cummings 2021). On the IUCN Red List it has been assessed as LC (Killeen et al. 2011 b).
