摘要: Steinernema cameroonense sp. n. and S. nyetense are two new species isolated from soil samples in Minkama, Obala Nkontangan, Nyete, respectively. is characterised by infective juvenile body length averaging 622 (490-693) mu m; pharynx of 108 (100-114) tail 76 (52-107) D E values 48 (42-56) 75 (48-116), The lateral field pattern 2, 4, 5, 6, 3, 2. First generation males can be recognised spicule 69 (51-85) GS = 64 (47-76); SW 170 (131-200); (48-76). averages 648 (565-708) 114 (104-127) 82 (54-112) 46 (37-50) 66 (43-89), 80 (67-98) (51-77); 198 (124-283); 55 (40-70). As inferred the sequence analysis ITS rDNA represent separate group genus distantly related to 'monticolum' 'feltiae-kraussei-oregonense' clades. According D2D3 LSU sequences Cameroon constitute a inner nodes phylogeny.
