A review is given of the Xiphinema specie occurring in the south-eastern part of Bahia, Brazil. Nine species were found, two of which are new: X. dimidiatum with mammillate tail, females are pseudomonodelphic; and; X. paritaliae, differing from X. italiae chiefly by larger size, not expanded lip region and weak Z differentiation in the uteri. The name X. vulgare Tarjan,1964 is provisionally retained. Brazilian males of X. surinamense differ those from Surinam in possessing two to four supplements. The other species found are: X. brevicolle, brasiliense, X. elongatum, X. krugi and X. ifacolum. Morphologyof juvenniles is dealt with wherer possible. Younger stages often have a more generalized tail shape than adults. Tail length tends to decrease slightly during ontogeny, whereas anal body width increases strongly. |
