Pala M, Casu S, Vacca RA (1981) Dugesia hepta, nuova specie di Planaria di acqua dolce di Sardegna appartenente alla superspecie Dugesia gonocephala (Duges) (Turbellaria, Tricladida). Bollettino della Societa Sarda Scienze Naturali 20: 97-107 |
Abstract / Notes
A planarian belonging to the group D. gonocephala s.l. was found in 13 sites in Sardinia (11 in the catchment area of the Rio Mannu of Porto Torres and 2 in that of the Coghinas). It is morphologically related to D. benazzii Lepori of Sardinia and Corsica but presents a different karyotype: 2n = 14; n = 7 chromosomes instead of 2n = 16; n = 8 chromosomes. The latter is the most common in the superspecies D. gonocephala of central European and Mediterranean distrubution areas. The planarian in question was considered a distinct species with the group D. gonocephala s.l. and the denomination D. hepta sp. nov. is proposed.
