Open publisher page 1 citations

Abstract

Xiphinema aaba sp.n. is described from northern KwaZulu-Natal, South Africa. The new species is characterised by a strongly ventrally curved body posture, didelphic sexual system, vulva near middle of body, absence of spines in uterus, pseudo-z-organ with mostly only four large oblong inclusions, conoid often subdigitate tail and presence of males with two to five well-developed ventromedian supplements. It belongs in Loof and Luc's (1990) group 5, and is compared with X. pongolense Hutsebaut, X. abrantinum Roca et Pereira, and X. dissimile Roca. Pereira et Lamberti.
