Abstract
Anew species of Rotylenchus Filip'ev, 1936 from Sierra de Cazorla, Spain, with males and \nfemales is decribed as R. cazorlaensis sp. n. Females are characterized by a truncate cephalic \nregion continuous with body, large size L = 1. 79 mm (1.44-2.28) and well developed stylet. \nClose to R. magnus Zancada, 1986 in large size and lateral field areolated only anteriorly, it differs \nin stylet length 53 !J.m (46.5-56.5) compared to 64 !J.m (59-70), lip region and position of \nphasmids. It resembles R. robustus (de Man, 1876) Filip'ev, 1936, but differs in areolations of \nlateral field. R. fallorobustus Sher, 1965 is recorded and described for the first time in Spain. \nKeywords: taxonomy, morphology, soil nematodes, Spain, spiral nematodes.
