Dissertation on some Peruvian snails

This is not a new publication, but already from 2008. It is a dissertation of Samira Guevara, who graduated in 2005 in Hamburg, Germany under supervision of Prof.Dr Klaus Bandel and Dr Bernhard Hausdorf. The subject of her thesis was the systematic treatment of snails collected in and around three National Parks in Peru. As this dissertation falls into the ‘grey literature’ I pay some attention to it, despite not being very recently published. The thesis is in Spanish, with summaries in German and English.

Snails were collected in the vicinity of Moyobamba (Bosque de Alto Mayo), Tingo Maria (Parque Nacional Tingo Maria), and Cuzco (Parque Nacional Manu). In total 5000 specimens were collected, belonging to 40 families and 136 species. The thesis gives more details for the families Helicinidae (10 species), Ceresidae (3 species) and Bulimulidae (9 species).

In the family Helicinidae, three new species are described: Helicina (Concentrica) bandeli, H. (C.) peruensis, and Alcadia (Microalcadia) kasteli. As the thesis was formally published in 2008, all species should have as author “Guevara, 2008”. The following pictures provide photographs of the holotype of each species, together with the type locality and the depository mentioned in the legends (ZMH is Zoologisches Museum, Universität Hamburg):

The type localities for Helicina (Concentricaperuensis respectively Alcadia (Microalcadiakasteli are: Dept. San Martin, Cataratas del Gera, 12 km SE Moyobamba, 500m, respectively Dept. San Martin, Cueva Huacharos de Palestina-Rioja, 44 km NW Moyobamba, 894 m.

From the nine species mentioned in the family Bulimulidae, I think three have been misidentified. Both Valentín Mogollón and I arrived at the same conclusions. We will report on these in a later stage.
