Ciao a tutti
Vi segnalo questo nuovo e interessante lavoro di H. Nordsieck in cui viene revisionato il genere Leucostigma A. J. Wagner 1919.
NORDSIECK, H., 2011 – Revision of the genus Leucostigma A. J. Wagner 1919 (Gastropoda: Stylommatophora: Clausiliidae). Archiv für Molluskenkunde, 140: 123-147.
Abstract: In this paper a revision of the genus Leucostigma A. J. Wagner 1919 based mainly on shell morphology is published. It contains only one species, L. candidescens (Rossmässler 1835), which is distributed in central and southern Apennine Italy. The species is subdivided into nine subspecies: Leucostigma candidescens candidescens, Leucostigma candidescens convertita (Flach 1907), Leucostigma candidescens dextromira n. ssp., Leucostigma candidescens leucostigma (Rossmässler 1836), Leucostigma candidescens megachilus (Paulucci, 1881), Leucostigma candidescens monticola n. ssp., Leucostigma candidescens opalina (Rossmässler 1836), Leucostigma candidescens paraconvertita n. ssp., and Leucostigma candidescens samnitica (Rossmassler 1842). Three of these subspecies, Leucostigma candidescens convertita, Leucostigma candidescens dexstromira n. ssp. and Leucostigma candidescens paraconvertita n. ssp., are dextral counterparts of certain normally (left-) coiled subspecies. The high diversity within the species is descrive and discussed.
Sicilia: bellissima per natura
