A SEM-study was conducted on the Swartvlei-population, resulting in a better understanding of the external head morphology, cephalic receptors, supplements and the midventral ridge in males. An interesting feature of these specimens is the sometimes huge, yellowish coelomocytes occurring in specific areas of the body.1 aSwart, A.1 aHeyns, J.1 aCoomans, A.  uhttps://nematodes.myspecies.info/node/29301732nas a2200157   4500008004100000020001400041245010500055210006900160260000800229300001200237490000800249520123700257100001801494700001601512856004601528       1993                        eng d  a0777-627600aTHE GENERA LONGIDORUS-MICOLETZKY, 1922 AND XIPHINEMA-COBB, 1913 (NEMATODA, LONGIDORIDAE) IN CAMEROON0 aGENERA LONGIDORUSMICOLETZKY 1922 AND XIPHINEMACOBB 1913 NEMATODA  cDec  a203-2300 v1233 aSoil 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.1 aSakwe, P., N.1 aCoomans, A.  uhttps://nematodes.myspecies.info/node/29401399nas a2200145   4500008004100000020001400041245013300055210006900188300001200257490000700269520090300276100001201179700001601191856004601207       1993                        eng d  a1164-557100aDESCRIPTION OF XIPHINEMA-ABEOKUTAE N-SP AND REDESCRIPTION OF X-PAULISTANUM CARVALHO, 1965, 2 RARE SPECIES (NEMATA, LONGIDORIDAE)0 aDESCRIPTION OF XIPHINEMAABEOKUTAE NSP AND REDESCRIPTION OF XPAUL  a393-3990 v163 aXiphinema abeokutae n. sp. from cocoa soil in Nigeria is described and illustrated. Only few specimens were found; the new species is characterized by having a lip area continuous with the rest of the body, a pseudo-Z-organ, a tail regularly conical, curved ventrad in both sexes, and the absence of medioventral supplements in the male. X. paulistanum Carvalho, 1965, found once in Sao Paulo, Brazil is redescribed on the holotype female and the allotype male (only one additional female was originally reported). Observations confirmed the original description, but permitted to clear the structure of the female genital system in detail : the anterior genital branch is composed of an uterus similar to that of the posterior branch, but the oviduct is reduced to an unorganized mass and the ovary is absent.

This species is characterized by two ventromedian cervical papillae, the shape of the spicules with widened manubrium and slender calomus with at mid-level a slight constriction provided with bristles in males, and by a barrel-shaped vagina, small triangular oblique vaginal sclerotized pieces and a single pair of postadvulvar lateral body pores in female. T. giennensis sp. n. closely resembles the '' Trichodorus aequalis '' species group, and more specifically T. sparsus Szczygiel, 1968.

Trichodorus magnus n. sp. is characterized in males, by the presence of one medioventral cervical papilla, shape of spicules (stout with indentation) and non-thickened terminal cuticle; in females, by the shape of the vaginal sclerotizations, the pore-like vulva in ventral view and a pair of postadvulvar sublateral body pores and in both sexes by the long body and long onchiostyle (62.5-71 mum). Trichodorus kilianae n. sp. is characterized in males by presence of a single cervical medioventral papilla, a non-thickened terminal tail cuticle and shape of spicules (slender, with septum in front of a clear but irregular indentation); in females by small vaginal sclerotizations and pore-like vulva in ventral view and in both sexes by a slender and long body, onchiostyle length of 45-49 mum and anterior position of the excretory pore.
