Four new species of Criconematoidea are described from Hoste Island, Chile. Criconema certesi n. sp. is distinguished by the fine, spine-like, cuticular extensions on body annuli; projection of annuli into rows of scales on posterior part of body; single, smooth, labial annulus set off by short collar from second (first body) annulus which is about same diameter as first (labial) annulus. Male with prominent caudal alae, slender curved spicules, and four incisures in lateral field. Ogma terrestris n. sp. is distinguished by small scales with rounded tips bearing minute, short bristles; scales number 21 at mid-body; and first (labial) annulus rounded, not retrorse, not set off from succeeding annuli, narrower in diameter from second (first body) annulus. Hemicycliophora macrodorata n. sp. is distinguished by its large size (L = 1.52 [1.28-1.72] mm); large stylet (146 [127-161] mum); annuli = 297 (280-315); tail slightly spicate, lateral field with or without interruptions of incisures, occasional anastomoses; and males with U-shaped spicules. Paratylenchus fueguensis n. sp. is distinguished by its prominent stylet with large, rounded knobs (4-5 mum across); cephalic region rounded not at all set off; lateral field with four incisures; lateral vulvar membranes present; and male tail short, strongly curved (almost 180 degrees ) ventrad.
从智利的霍斯特岛描述了四新种环线虫。塞尔特环线虫新种的特征为虫体环纹上有细小、刺状的角质层延伸物;环纹在虫体后部形成鳞片排;单一、光滑的唇环由短领与第二(第一节)环纹隔开,第二环纹直径与第一(唇)环纹大致相同。雄虫具明显的尾翼、细长弯曲的交合刺以及侧区四条侧线。陆地奥格线虫新种的特征为具圆尖且带有微小短刚毛的小鳞片;虫体中部有21个鳞片;第一(唇)环纹圆形,不后翻,不与后续环纹隔开,直径比第二(第一节)环纹窄。大咽半环线虫新种的特征为体型大(体长 = 1.52 [1.28 - 1.72] 毫米);口针大(146 [127 - 161] 微米);环纹 = 297(280 - 315);尾部稍具刺,侧区侧线有或无中断,偶尔有吻合;雄虫交合刺呈U形。火地岛矮化线虫新种的特征为具突出的口针,口针上有大的圆形瘤(直径4 - 5微米);头部区域圆形,完全不分开;侧区有四条侧线;有侧阴膜;雄虫尾部短,强烈向腹面弯曲(近180度)。
