Hydrocena canttabrica sp. nov. is described from caves in Cantabria, Spain. Unlike the two other extant European species, the Dinaric Hydrocena cattaroensis (Pfeiffer, 1841) and the Macaronesian Hydrocena gutta Shuttleworth, 1852, which are both epigean, the new species is the first cave-dwelling Hydrocenidae already known.

Why some animals can regenerate while many others cannot remains a fascinating question. Even amongst planarian flatworms, well-known for their ability to regenerate complete animals from small body fragments, species exist that have restricted regeneration abilities or are entirely regeneration incompetent. Towards the goal of probing the evolutio...

The Iberian Peninsula represents a diversity hotspot for the genus Dicranopalpus. However, most taxa are insufficiently defined.

Recent studies have shown that the speciose Holarctic genera of Leiobunum C.L. Koch, 1839 and Nelima Roewer, 1910 are polyphyletic taxa, and therefore, the traditional diagnostic characters for these European genera of Leiobuninae Banks, 1893 (respectively, the presence or absence of tubercle rows on leg coxae) are unsuitable. We present the descri...

Oestophora urbionensis, a new species from Duruelo de la Sierra, on southwestern slopes of Sierra de Urbión (between La Rioja and Soria provinces, Spain) is described. Judging from the shell, it is very similar to O.silvae Ortiz de Zárate López, 1962 and anatomical differentiation is mainly based on the greater length of dart sac complex, free ovid...
