A DICHOTOMOUS KEY FOR THE IDENTIFICATION OF SPECIES OF XIPHINEMA (NEMATODA: DORYLAIMIDA) WITHIN THE X. AMERICANUM -- GROUP

F. Lamberti, M. Carone

The key is based mainly on the length of the body and the odontostyle, on the value of ratios a, c, c' and V, and on the lip region shape and is complemented by tail shapes.
