Note. This synanthropic species, of Oriental origin ( Lillig 1999) and now cosmopolitan, has long been known as a pest of grain and flour products. It is widespread and common across all adjacent regions ( Godron 1863; Everts 1903, 1922; Libbrecht 1988; Köhler & Klausnitzer 1998; Lillig 1999; Soldati 2007; Thomaes et al. 2025).
