Abstract

We present the first records of the family Boettgerillidae, and the species Boettgerilla pallens Simroth, 1912 in the gastropod fauna of Serbia. The history of the discovery of B. pallens in Bulgaria is summarized, and new faunistic records from the country are provided. The anatomy of Bulgarian specimens is described, compared with specimens from Switzerland, and the general details of the habitus and anatomy of the species are discussed. We comment on the habitat preferences and invasive potential of the species.
