Resumen

Xiphinerna barense sp. n. is described from Italy. It is a bisexual, amphidelphic, peg-tailed species found in the rhizosphere of olive trees and blackberry bushes. X. barense differs from X. diversicaudaturn (Micoletzky, 1923) Thorne, 1939 and from X. vuittenezi Luc, Lima, Weischer et Flegg, 1964 in the length of the body which is intermediate between the two; from the former species by its shorter tail and in not having a pseudo-Z organ differentiation and from the latter species by its more pronounced and pointed tail peg and its high ratio of males. It differs from X. israeliae Luc, Brown et Cohn, 1982 by its more robust body, lower c' value and rounded tail.
