We consider its relatively larger body size and the morphology of the aedeagus as the main features for distinguishing it from other similar species in the subgenus Langelandia (Dajoz 1969; Orousset 1989). For Bulgaria, L. anophthalma is mentioned without exact locality by Bekchiev and Guéorguiev (2015): 339. The species is not listed for Bulgaria in both editions of the Catalogue of Palaearctic Coleoptera (Ślipiński and Schuh 2008; Schuh 2020). Herein, we confirm the presence of L. anophthalma in Bulgaria and record the notable cases of the species inhabiting the burrows (including the nesting materials) of the European souslik (Spermophilus citellus L.) (Fig. 10).
