Description
Genus Iberozospeum Jochum, Kneubühler, Prieto and Neubert, n. gen.
Type species Zospeum zaldivarae (Prieto et al., 2015 in Jochum et al., 2015a).
Differential diagnosis Iberozospeum, n. gen., differs from Zospeum by the generally smaller shell (on the average ca. 1.2 mm). The radula ribbon differs by its greater length, regular broadness below the adhesive zone and its perfectly straight base. Radular teeth are smaller and more numerous per transverse row. The basal plates are more compact and shorter than the long, narrow versions in Zospeum species. At the microstructural level, it differs by localized, dense, rough, overlapping wedge-like scales of crystallographic structure on the surface of the columellar lamellae. These sites are located only at the points of contact with the columellar muscle. It also appears to differ by the correlating, vascularized humps of columellar muscle to the corresponding zones of microstructural texture on the lamellae.
Etymology The name Iberozospeum derives from combining the region of origin of the type species, the Iberian Peninsula, and the generic name of Zospeum (Bourguignat, 1856).
Included taxa: all hitherto known species from the Iberian Peninsula:
Iberozospeum schaufussi (von Frauenfeld, 1862). Iberozospeum bellesi (Gittenberger, 1973). Iberozospeum biscaiense (Gómez & Prieto, 1983). Iberozospeum vasconicum (Prieto et al., 2015 in Jochum et al., 2015a).
Iberozospeum zaldivarae (Prieto et al., 2015 in Jochum et al., 2015a).
Iberozospeum percostulatum (Alonso et al., 2018). Iberozospeum praetermissum (Jochum et al., 2019). Iberozospeum gittenbergeri (Jochum et al., 2019).
