Esperiana daudebartii : Karaman & Karaman (2007).

Microcolpia daudebartii: Martinović-Vitanović et al. (2013) .

Morphology. Medium-sized snails (conical elongated shell up to 25 mm high). Shell is dark reddish brown, finely striated, and consists of 7–8 flat whorls. Aperture is lanceolate with strong basal groove. For more details see Welter-Schultes (2012: 36, figure at the bottom of the page).

Distribution and ecology. Ponto-pannonic species inhabiting similar habitats as Esperiana esperi . In Serbia, it is found in large Pannonian river-systems (Danube, Sava, Tisza) as well as in Drina, Kolubara and Velika Morava-Zapadna Morava-Južna Morava drainages.

Other remarks. This species has variable morphology, including a few morphs and subspecies. Among those morphs Microcolpia d. daudebartii and M. d. acicularis are among the most known. Unlike M. d. acicularis , which has a wide distributional range (Ponto-Pannonic), M. d. daudebartii has a limited range (Drava River and Central Hungary / Budapest). Recent morphological analyses have claimed distinction of those subspecies ( Neubauer et al. 2014), contrary to genetic analyses ( Falniowski et al. 2020). At the genus level, there is a similar unresolved taxonomic issue. According to some authors (Cummings & Lydeard 2019; Falniowski et al. 2020) Esperiana and Microcolpia are separate genera due to genetic differences, while authors prioritizing morphology ( Glöer 2019), consider those as subgenera. On the IUCN Red List it has been assessed as LC ( Fehér 2010b).
