Three new species of Etamphidelus are described from Orange Bay, Hoste Island, Chile. All three are distinguished from previously described species by their numerous longitudinal cuticular ridges. E. acucephalus n. sp. is further distinguished by its extremely narrowed anterior body region and posteriorly situated amphids. E. fueguensis n. sp. is distinguished from E. acucephalus by its anteriorly located amphideal fovea, fewer cuticular ridges, smaller V-an/tail ratio and presence of males. E. yamani n. sp. is more similar to E. fueguensis n. sp. differing from it by a wider head end, more posteriorly located excretory pore, longer V-an/tail ratio, more numerous cuticular ridges and smaller spermatozoa. E. puccinelliae (Lorenzen, 1966) Andrássy, 1977 is transferred to Paramphidelus puccinelliae (Lorenzen, 1966) n. comb. The generic diagnosis of Etamphidelus is amended, and a key to species is presented.
从智利霍斯特岛奥兰治湾描述了伊塔姆菲德线虫属的三个新物种。这三个新物种与先前描述的物种的区别在于它们有许多纵向角质脊。尖头伊塔姆菲德线虫新种进一步的区别特征在于其身体前部区域极度狭窄以及头感器位于身体后部。火地岛伊塔姆菲德线虫新种与尖头伊塔姆菲德线虫的区别在于其头感器位于身体前部、角质脊较少、V-肛门/尾的比例较小以及有雄性个体。亚马尼伊塔姆菲德线虫新种与火地岛伊塔姆菲德线虫新种更为相似，但与之不同的是，它的前端更宽、排泄孔位置更靠后、V-肛门/尾的比例更长、角质脊更多以及精子更小。普氏伊塔姆菲德线虫（洛伦岑，1966年）安德拉希，1977年被转移至新组合的碱茅帕拉姆菲德线虫（洛伦岑，1966年）。对伊塔姆菲德线虫属的属级诊断进行了修订，并给出了物种检索表。
