Aperture showing minimum separation from the penultimate whorl, 0.49 – 0.74 mm in height and 0.44 – 0.68 mm in diameter, ovoid in shape, very prominent external curvature; in the upper side a slight angulation is observed, continued in the outer side with a more marked undulation if observed from the external side of the aperture; the base shows a semi-circular incision. Outer lip not thickened, but everted in its whole extension.	en	Quiñonero-Salgado, Sergio, López-Soriano, Joaquín, Alonso, Álvaro (2024): A new subspecies of Tarracospeum raveni (Gastropoda: Moitessieriidae) forTarragona province (NEIberian Peninsula).

03F587B0FF89FF8DFF6EFE34FC17E6E9.taxon	description	Dimensions: See Table 1 and Fig. 3. Habitat: Stygobitic. Shells were washed out from their habitat, likely after a sudden rise of the subterranean water levels. Most shells had a fresh appearance, given their transparent colour.	en	Quiñonero-Salgado, Sergio, López-Soriano, Joaquín, Alonso, Álvaro (2024): A new subspecies of Tarracospeum raveni (Gastropoda: Moitessieriidae) forTarragona province (NEIberian Peninsula).

03F587B0FF89FF8DFF6EFE34FC17E6E9.taxon	distribution	Distribution: Known from a spring in Vilaverd (Font del Mas) and two springs at Montblanc (Font de la Ceba and Font del Llorach), all at the Francolí River basin. Differentiating characters: The main differences between the new subspecies T. raveni incisum and the subspecies is the presence of an incision in the lower part of the peristome (Fig. 2). Although we consider the new taxon as a subspecies, given its geographic separation with the two known populations of the subspecies (from the Gaià River basin), and the presence of constant and distinctive shell characters between them, it cannot be ruled out that it may represent a fully differentiated species. Since the shells of both taxa are quite similar in overall characters, and in the absence of anatomical or genetic data, or any likely intermediate population, we cautiously consider it a subspecies. In any case, this work shows the richness of our groundwater ecosystems, which have been only superficially examined until now.	en	Quiñonero-Salgado, Sergio, López-Soriano, Joaquín, Alonso, Álvaro (2024): A new subspecies of Tarracospeum raveni (Gastropoda: Moitessieriidae) forTarragona province (NEIberian Peninsula).
