Abstract


Six new species of Xiphinema from the mediterranean region are described. Five of them, namely X. sphaerocephalum from Spain, X. nuragicum from Italy, X. adenohystherum from Algeria, X. cohni from Israel and X. macrogastrum from Turkey, were previously considered as X. turcicum Luc et Dalmasso, but all differ from it in not having any Z differentiation in the female genital tract (X, turcicum possesses a rudimentary Z pseudo-organ) and in having large spines in the uterus (never observed in X. turcicum). X. hispanum sp. n. from Spain resembles X. aceri, from which it differs by its longer body and differently shaped lip region, and X. diannae from which it differs by its longer body, posterior vulva and wider tail.
