Orexana [1] is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae. [1]
It is distributed along west coast of Morocco and Canary Islands.
Species within the genus Orexana include:
Helicoidea is a taxonomic superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora.
Candidula is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae, . the hairy snails and their allies.
Geomitra is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae.
Xeroplexa intersecta is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae. It was previously included within the genus Candidula.
Xerocrassa is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Geomitridae.
Xerocrassa cisternasi is a species of air-breathing land snail, a pulmonate gastropod mollusk in the family Geomitridae. This species is endemic to Spain, where it is restricted to the north-eastern part of the island of Ibiza and the surrounding islets. The species joined at least 10 subspecies
Xerogyra grovesiana is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae.
Zarateana rocandioi is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae.
Xeroplexa is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae, the hairy snails and their allies. The genus is mainly distributed along western Iberian Peninsula, although X. intersecta spreads from northern Iberian Peninsula to central Europe and British Islands. Xeroplexa species were within genus Candidula until a molecular phylogeny revealed the polyphyly of Candidula, and the genus Xeroplexa Monterosato, 1892 was recovered.
Geomitridae is a taxonomic family of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
Orexana ultima is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae, the hairy snails and their allies.
Zarateana is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae, the hairy snails and their allies. The genus is endemic to the Iberian Peninsula.
Xeroplexa setubalensis is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae.
Xerogyra is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae.
Xeroplexa carrapateirensis is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae. The species epithet carrapateirensis is an adjective derived from the type locality near Carrapateira.
Xeroplexa scabiosula is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae. Although this species was named by Locard (1899), it was treated as synonym of X. belemensis by Gittenberger (1993).
Xeroplexa strucki is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae. Although named by Maltzan (1886), no differences from X. olisippensis were indicated and Gittenberger therefore treated them as synonyms. However, the present study has revealed that the W. Algarve populations named as strucki and similar snails from the coast of W. Baixo Alentejo differ consistently in having a much shorter penial flagellum.
Microxeromagna is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Helicellinae of the family Geomitridae.
Cernuellopsis is a genus of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Geomitridae. It contains a single species, Cernuellopsis ghisottii. This species is endemic to the Italian Peninsula.
Backeljaia is a genus of small to medium-sized, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae, the hairy snails and their allies.
