Rotylenchus cazorlaensis sp.n. and new record of R. fallorobustus sher, 1965 (Nematoda: Tylenchida) from south-eastern Spain

Abstract

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