Description
Localities and material: 1489 specimens. Province of CastelloÂn: 58M, 96I. Lc: 12. Province of Valencia: 534M, 547I. Lc: 42. Province of Alicante: 124M, 130I. Lc: 14. A more precise characterization of the localities of capture of the latter species can be found in RodrõÂguez BabõÂo and Onteniente (1992), Onteniente (1997) and Onteniente et al. (1998).
Characters. Length 57±148 mm (av. 90.5, SD 17.4). Diameter: maximum 2.75±6.0 mm (av. 4.47, SD 0.76), postclitellar 2.6±5.0 mm (av. 4.05, SD 0.54). Number of segments: 122±188 (av. 150.4, SD 14.12). Weight: 0.35 ±2.05 g (av. 0.91, SD 0.32). First dorsal pore in 7/8 (4.7%), 8/9 (25.6%), 9/10 (55.8%), 10/11 (6.9%) or 11/12 (7.0%). Perithecal papillae in ix±xi (99.44%) or ix±xii (0.56%). Porophores: half xiv±half xvi (100%). Clitellar anterior papillae in xxvii (4.85%), xxviii (6.41%) or xxix (6.32%). Clitellar posterior papillae in xxx and xxxii (21.02%); xxx, xxxii and xxxiii (62.91%) or xxx, xxxii-xxxiv (16.10%). Clitellum: anterior end in: 1/ n xxv (1.6%), xxvi or 1/ n xxvi (8.2%), xxvii or 1/ n xxvii (80.4%), or xxviii (9.8%); posterior end in: 1/ n xxxiv or xxxiv (96.7%), or 1/ n xxxv (3.3%). Tubercula pubertatis of tripartite origin, in continuous band, anterior end in 1/ n xxx (27.3%) or xxxi (72.7%), posterior end in xxxiii (79.1) or 1/ n 34 (20.9%). Typhlosole pennate (®gure 4b), anterior end in xx (20%), xxi (36%) or xxii (44%); posterior end in xc±cxxiii (av. 105.4, SD 7.5). Atyphlosolate segments: 23±59 (av. 42.8, SD 8.5).

Karyology. Two of the three specimens showed a triploid karyotype, with 3 n 554 (®gure 5c), the third one being diploid (2 n 536).
We have assigned these new species to the genus Nicodrilus BoucheÂ, 1972 instead of Allolobophora Eisen, 1874 or Aporrectodea O È rley, 1885 due to the fact that the ®rst is a genus with detailed diagnoses, based on the close phylogenetic relationship among the component species and, therefore, more natural from the evolutive point of view (BoucheÂ, 1972). On the contrary, the genera Allolobophora and Aporrectodea sensu lato have simple, clearly arti®cial diagnoses.
