Vitrea vereae n. sp. is described from Bulgaria. It was found in the town of Stara Zagora and in the massif of Sarnena Sredna Gora. Habitat data are provided.A new Vitrea from Bulgaria

According to the current state of knowledge the terrestrial gastropod fauna of Bulgaria includes 226 species and 33 subspecies (excluding nominate ones), making altogether 259 taxa. The following new data are presented: updated nomenclature of 50 taxa, synonymisation of 17 taxa; taxa whose presence in Bulgaria was discovered and those which were described as new to the science after the publication of the last checklist (1998) are now included, six taxa are evaluated as introduced; the taxonomic status of 13 taxa is regarded as unclear. Fifty seven taxa are regarded as endemic to Bulgaria, and 33 as endemic to the Balkan Peninsula; 60 taxa are regarded as rare.

The genital anatomy of Orcula jetschini (Romania), Orcula zilchi (Bulgaria), and Orcula wagneri (Albania) is described. Based on anatomical features (morphology of the penial caecum) shell characters (sculpture and shape) and unpublished molecular data the genus Orcula is subdivided into three subgenera. Orcula zilchi was classified within the monotypic subgenus Orcula (Hausdorfia) subgen. n.; Orcula jetschini, Orcula wagneri, and Orcula schmidtii were classified to Orcula (Illyriobanatica) subgen. n. (type species: Pupa schmidtii) whereas the other Orcula species remain in the nominotypical subgenus. Orcula (Hausdorfia) is known from South-Eastern Bulgaria and North-Western Turkey, Orcula (Illyriobanatica) inhabits Western Romania, North-Western Greece, Albania, Macedonia, Kosovo, and Montenegro. The nine species of Orcula (Orcula) are known mainly from the Alps and the Western Carpathians (from Eastern France to Eastern Hungary and Slovakia).The occurrence of only one Orcula species namely Orcula jetschini is verified from Romania. Available information suggests that data on the Romanian occurrence of Orcula dolium and Orcula gularis were based on wrongly identified specimens. Sphyradium dobrogicum (=Orcula dobrogica) is considered as a synonym of Sphyradium doliolum.
