Fig. 10 .

Material. 1♂, Mamer , 23.VI.[1890], F. Ferrant lgt. ( MNHNL138556 ) .

Note. This minute synanthropic species, most probably of Central American origin ( Delobel & Tran 1993) and cosmopolitan for some time, is generally found in bakeries and flour mills in adjacent regions, except in Saarland ( Everts 1903; Libbrecht 1988; Köhler & Klausnitzer 1998; Lillig 1999; Thomaes et al. 2025). In Lorraine, the species is known from old records in Vosges ( Soldati 2007) and has been found very recently in Meurthe-et-Moselle (F. Soldati in litt.). Its current presence in Luxembourg remains doubtful. It is most likely that Ferrant collected this specimen in his own mill at Thillsmillen (formerly Ferrantsmillen).
