Land and freshwater molluscs are the most abundant non-arthropod invertebrates from inland habitats worldwide, playing important ecological roles and some being important pests in agriculture. However, despite their ecological, and even economic and sanitary importance, their local diversity in many European regions is not perfectly understood, with a particularly notableknowledge gap in the northern Iberian malacofauna. This work aims at providing a revised checklist of continental gastropods and bivalves from the Asturias (northern Spain), based on the examination of newly collected and deposited material and on the critical analysis of published and gray literature. A total of 165 molluscan species are recognized. Ten species constitute new records from Asturias and seven from northern Iberian Peninsula. Seventeen species are introduced or invasive, evidencing the current increase of the bioinvasion rate in continental molluscs. Furthermore, all these exotic species are parasite transmitters or trematode intermediate hosts, and thus represent a potential bio-sanitary risk for human and other animal health. The provided data strongly suggest that the increase of invasive freshwater snail species can lead to an increase in parasitic infections, and this is a crucial point that transcends the merely scientific to the political-social sphere.

“…Z. suarezi (Gittenberger, 1980) and deposited in the BOLD data base under this name was revised (Jochum et al, 2019) and is now in sync with this investigation, I. schaufussi (von Frauenfeld, 1862). Caves harbouring two to three different morphotypes are considered not unusual (Alonso et al, 2018). Despite this suggested richness, only eight species have been formally described, including I. schaufussi (von Frauenfeld, 1862), I. bellesi (Gittenberger, 1973), I. biscaiense (Gómez & Prieto, 1983), I. vasconicum (Prieto et al, 2015in Jochum et al, 2015a, I. zaldivarae (Prieto et al, 2015in Jochum et al, 2015a, I. percostulatum (Alonso et al, 2018) and recently, I. gittenbergeri (Jochum et al, 2019) and I. praetermissum (Jochum et al, 2019).…”

The subterranean realm of the Cantabrian-Pyrenean region of northern Spain harbours a rich diversity of Zospeum. Due to their tiny size and the difficulty of finding them alive, scarce animal material has been available for scientific investigation. Recent investigations of Zospeum shells have provided valuable, but limited insights towards our understanding of the evolutionary processes occurring within this taxon in northern Spain. In an integrative study, we investigate 57 populations of Zospeum from northern Spanish caves using two mitochondrial (COI and 16S) and two nuclear markers (H3 and 5.8 S rRNA + ITS2). Revealed is a separate radiation of the northern Spanish species for which the new genus, Iberozospeum, is proposed. The independent radiation of Dinaric Zospeum from that of northern Spain justifies the designation of Iberozospeum n. gen. Morphological evidence is provided via histological analysis of Iberozospeum vasconicum and SEM analyses of radulae of eastern Alpine, Dinaric and Iberian species. Important differences in morphological structure and character states are presented, including the first view of the sexually mature female and the presence of the giant albumen gland in an individual of the subterranean, troglobitic Carychiidae. Significant differences are revealed in superficial crystallographic structure of the columellar lamellae, the morphology of the columellar muscle and in the radula. Radular ribbon length, ribbon broadness, straightness of the ribbon base and cusp configuration are distinctive in the Iberian species. One new species is described corroborated by genetic and morphological characters.

“…Insufficient knowledge, causing doubts about the identity of two of these species, Z.schaufussi and Z.suarezi , has blocked further descriptions of this potentially very speciose radiation in a region where many caves are inhabited by two or three different morphotypes (Alonso et al 2018).…”

The present study aims to clarify the confused taxonomy of Z.schaufussi von Frauenfeld, 1862 and Zospeumsuarezi Gittenberger, 1980. Revision of Iberian Zospeum micro snails is severely hindered by uncertainties regarding the identity of the oldest Iberian Zospeum species, Z.schaufussi von Frauenfeld, 1862. In this paper, we clarify its taxonomic status by designating a lectotype from the original syntype series and by describing its internal and external shell morphology. Using SEM-EDX, we attempt to identify the area of the type locality cave more precisely than “a cave in Spain”. The shell described and illustrated by Gittenberger (1980) as Z.schaufussi appears not to be conspecific with the lectotype shell, and is considered a separate species, Z.gittenbergeri Jochum, Prieto & De Winter, sp. n. Zospeumsuarezi was described from various caves in NW Spain. Study of the type material reveals that these shells are not homogenous in shell morphology. The holotype shell of Z.suarezi is imaged here for the first time. The paratype shell, illustrated by Gittenberger (1980) from a distant, second cave, is described as Zospeumpraetermissum Jochum, Prieto & De Winter, sp. n. The shell selected here as lectotype of Z.schaufussi, was also considered a paratype of Z.suarezi by Gittenberger (1980). Since this specimen is morphologically very similar to topotypic shells of Z.suarezi, the latter species is considered a junior synonym of Z.schaufussi (syn. n.). The internal shell morphology of all these taxa is described and illustrated using X-ray Micro Computer Tomography (Micro-CT).
