Diagnostic characters. Oval thin shell; truncate subvertical posterior margin; radial angulation from the beaks to the postero-ventral angle; radial rows of minute, subcylindrical pustules. Prodissoconch: not available.
Remarks. Poromya granulata, as figured in literature, seems to exhibit some degree of variability in terms of heigth/length ratio, shape of the anterior side (rounded to oval), sharpness of the posterior angulation and heigth of the posterodorsal area.
Occurrence. Box-corer sample BC72 (1 specimen); cores BC05 (5), BC72 (1). Maximum length: 3 mm.
Distribution and habitat. The species is distributed from boreal and subarctic northern Atlantic waters southward to Brazil and Senegal, entering the Mediterranean as far east as Israel. It is a mud burrower found from about 30 to 1300 m depth, gradually deepening moving southward (Nordsieck 1969; Barash & Danin 1992; Poppe & Goto 1993; Oliver et al. 2016).
Fossil record. Pliocene of southern Italy (Monterosato 1872); bathyal Pleistocene of southern Italy (Di Geronimo & La Perna 1997).
