Diagnostic characters. Oval to subrounded, variously twisted shell; rounded byssal notch on the right valve; outer surface with either randomly arranged fluted spines or uneven growth markings only. Prodissoconch: shell type ST- 2A; P-2 length about 200 µm; roundish, weakly inequilateral outline more expanded posteroventrally; convex profile; P-1/P-2 boundary ill-defined; P-2 with commarginal cordlets towards the nepioconch; shallow sinuation on the antero-ventral margin of P-2; transition to the nepioconch well marked.
Remarks. Pododesmus aculeatus (Müller, 1776), sometimes considered a different species, is herein regarded as a synonym (Winckworth 1922; Peñas et al. 2006; CLEMAM 2016).
Occurrence. Box-corer samples BC04 (19 specimens), BC05 (20), BC10 (2), BC11 (56), BC19 (1), BC22 (17), BC41 (10), BC66 (353), BC67 (319), BC68 (19), BC70 (27), BC71 (2913), BC72 (1597); cores BC04 (6), BC05 (100), BC21 (29), BC51 (13), BC67 (61), BC72 (196). Maximum height: 9.5 mm.
Distribution and habitat. Heteranomia squamula ranges from the northern Atlantic (North America, Iceland and Norway) to western Mediterranean, from the intertidal belt to about 1000 m depth. It lives on a variety of small hard substrates including Lophelia deep-water corals, Corallium rubrum, algae and crustaceans, denoting a decrease in sedimentation rates in an upper bathyal setting (Nordsieck 1969; Poppe & Goto 1993; Pons-Moyà & Pons 1999; Crocetta & Spanu 2008; Oliver et al. 2016). In the Santa Maria di Leuca CWC biotope it was very abundantly found in framework-building coral, coral rubble and solitary coral thanatofacies (Rosso et al. 2010).
Fossil record. Miocene to Recent (Monegatti & Raffi 2001; Petersen 2004), being frequent in Pleistocene bathyal deposits of central and southern Italy (Di Geronimo & Bellagamba 1985; Di Geronimo & La Perna 1997; Di Geronimo et al. 2005); it characterizes recurring associations in the Lower and Middle Pliocene of northern Italy (Ceregato et al. 2007; Tabanelli 2008).
