L. Barsi, F. Lamberti

Abstract


Five undescribed species of Xiphinema from the former territory of Yugoslavia are described. X. horvatovicae sp.n. was found in the rhizosphere of Pinus nigra near Cista Provo in Croatia. It is a bisexual species with a body length of 3.1 mm, frontally flattened and laterally rounded lip region, separated from the rest of the body by a depression, odontostyle length of ca 123 µm, vulva about 44%, equally developed genital branches with numerous spiniform structures in the uterus, short tail, mostly convex-conoid, rarely near hemispherical, with ventrally directed conical peg. X. horvatovicae sp.n. resembles X. aequum Roca et Lamberti, 1988, X. Illyricum sp.n., X. Macedonicum sp.n. and X. thorneanum Luc, Loof et Coomans, 1986. X. Illyricum sp.n. was found in the rhizosphere of Carpinus orientalis near Danilovgrad in Montenegro. This species is characterized by body length of 2.9 mm, frontally flattened and laterally rounded lip region, separated from the rest of the body by a slight depression, odontostyle length of 130 mm, vulva about 44%, equally developed genital branches with numerous spiniform structures in the uterus, convex-conoid short tail with ventrally directed conical peg, rarely without peg and absence of males. X. Illyricum sp.n. resembles X. aequum Roca et Lamberti, 1988, X. horvatovicae sp.n., X. macedonicum sp.n. and X. thorneanum Luc, Loof et Coomans, 1986. X. macedonicum sp.n. was found in the rhizosphere of Carpinus orientalis and Platanus orientalis on the bank of the Konska river near Konsko, Macedonia. It is a bisexual species with a body length of 3.54 µm, frontally flattened and laterally rounded lip region, separated from the rest of the body by a weak depression, odontostyle length of 130.5 µm, vulva about 47%, equally developed genital branches with numerous spiniform structures in the uterus, convex-conoid short tail with ventrally directed conical peg. X. macedonicum sp.n. resembles X. aequum Roca et Lamberti, 1988, X. horvatovicae sp.n. and X. Illyricum sp.n. Xiphinema sp.A from Bosnia and Herzegovina and Xiphinema sp.B from Slovenia are described but they are not named because only one female and juvenile stages and two females were available, respectively.
