Taxonomic clarification of three taxa of Iberian geomitrids, Helix montserratensis Hidalgo, 1870 and subspecies (Gastropoda, Pulmonata), based on mor…

Revisión taxonómica de tres taxones de geomítridos ibéricos, Helix montserratensis Hidalgo, 1870, y subespecies (Gastropoda, Pulmonata), basada en datos morfo–anatómicos Helix montserratensis (actualmente Xerocrassa montserratensis) es un geomítrido ibérico descrito por Hidalgo en 1870 en Montserrat (Barcelona, España). Sobre la base de varios caracteres conquiológicos, se describieron dos taxones muy similares, como variedades de este taxón: Helix montserratensis betulonensis y otro menos nombrado, Helix montserratensis delicatula. Estas variedades, sobre todo betulonensis, se han considerado subespecies de X. montserratensis, aunque algunos autores las consideran especies diferentes, basá…
Contribution to the knowledge of the terrestrial slugs (gastropoda, pulmonata) of the Maghreb
2017
As a result of recent malacological campaigns of our team in Algeria and Morocco, some previous samples, and after reviewing the literature, specially the recent papers about the Tunisian slugs, we produce a list of slugs of the Maghreb (Algeria, Morocco and Tunisia), with comments or discussion on each of the 17 species that form this list. We report for the first time Deroceras laeve (O.F. Müller, 1774) and Testacella haliotidea Draparnaud, 1801 in North Africa, although with reservations regarding the latter. We also report Lehmannia nyctelia (Bourguignat, 1861) for the first time in Morocco, concretely in the Chafarinas Islands, of Spanish sovereignty
Descripción de un nuevo geomítrido para la malacofauna española: Xerocrassa penalveri n. sp. (Mollusca, Gastropoda Stylommatophora).
2022
Se describe un nuevo geomítrido ibérico, Xerocrassa penalveri n.sp., que ha sido descubierto en Sierra Espuña en la Región de Murcia (SE España). Se caracteriza tanto a nivel conquiológico como del aparato reproductor además de la rádula y la mandíbula, y se compara con las especies de geomítridos más similares como Xerocrassa cobosi, X. edmundi y X. penchinati. Se realiza un estudio morfométrico de diversos órganos del aparato reproductor y de caracteres conquiológicos que permite su identificación. Estas especies de Xerocrassa se diferencian de X. penalveri n. sp. principalmente atendi…
Intermediate hosts of Angiostrongylus cantonensis in Tenerife, Spain.
2015
The nematode Angiostrongylus cantonensis is the causative agent of human angiostrongy- liasis, the main clinical manifestation of which is eosinophilic meningitis. Although this para- site has been found recently in its definitive rat host in Tenerife (Canary Islands, Spain), showing a widespread distribution over the north-east part of the island, there are no avail- able data regarding which snail and/or slug species are acting as intermediate hosts on this island. Consequently, the objective of this work was to determine the possible role of three mollusc species, Plutonia lamarckii , Cornu aspersum and Theba pisana , as intermediate hosts of A . cantonensis in Tenerife. Between 2011 and…
Molecular phylogeny of the genus Chondrina (Gastropoda, Panpulmonata, Chondrinidae) in the Iberian Peninsula
2022
[EN] Chondrina Reichenbach, 1828 is a highly diverse genus of terrestrial molluscs currently including 44 species with about 28 subspecific taxa. It is distributed through North Africa, central and southern Europe, from Portugal in the West to the Caucasus and Asia Minor in the East. Approximately 70% of the species are endemic to the Iberian Peninsula constituting its main center of speciation with 34 species. This genus includes many micro endemic taxa, some of them not yet described, confined to limestone habitats (being strictly rock-dwelling species). They are distributed on rocky outcrops up to 2000 m.a.s.l. It is a genus of conical-fusiform snails that differ mainly in shell characte…
Hallazgo de una población de Quickella arenaria (Potiez & Michaud, 1835) (Mollusca, Gastropoda, Succineidae) en Castilla-La Mancha (España)
2017
Troballa d’una població de Quickella arenaria (Potiez & Michaud, 1835) (Mollusca, Gastropoda, Succineidae) a Castella-la Manxa (Espanya) Després de l’estudi d’un gran nombre de surgències a la província de Conca (Espanya) es comunica la troballa, per primera vegada a Castella-la Manxa, del gasteròpode succineid Quickella arenaria, poc conegut a Espanya. A més a més s’assenyalen les amenaces que suporta la població al lloc on viu i se’n proposa la conservació.
