The genera Longidorus Micoletzky, 1922 and Xiphinema Cobb, 1913 (Nematoda : Longidoridae) in Cameroon.

BELGIAN JOURNAL OF ZOOLOGY, 123(2):203-230.

Soil samples collected by the first author from the rhizosphere of a variety of food and vegetable crops in the South West, West and North West Provinces of Cameroon contained eight known longidorid species, namely, Longidorus laevicapitatus WILLIAMS, 1959; L. pisi EDWARD et al., 1964; Xiphinema elongatum SCHUURMANS STEKHOVEN and TEUNISSEN, 1938; X. ifacolum LUC, 1961; X. longicaudatum LUC, 1961; X. nigeriense LUC, 1961; X. setariae LUC, 1958; and X. vitis HEYNS, 1974. The male, first-, second-, and third-stage juveniles of X. nigeriense are described for the first time. The male supplements consist of an adanal pair and a single ventromedian one. The value of the ratio of the hyaline terminal portion of the tail/tail tip width, for any given juvenile stage, was higher in X. longicaudatum than in X. nigeriense, and this ratio was used to separate their juveniles. It appears to be a reliable character for separating the juvenile stages of both species in mixed populations. A single male of X. setariae with a rudimentary reproductive system found in one population is the second ever recorded, the first one reported by TARJAN (1964, as X. vulgare). All species except L. pisi are first records from Cameroonian soils.
