Abstract

The morphology of L4 of Cylicostephanus minutus, Cylicotetrapedon bidentatus, Petrovinema poculatum, Cylicocyclus radiatus, C. triramosus, Cylicodontophorus euproctus, C. mettami, C. mongolicus, Poteriostomum imparidentatum, Gyalocephalus capitatus and Craterostomum acuticaudatum is discussed. The species are named in accordance with the new system, which is outlined in the introduction. The criteria for the identification of larvae killed during their 4th skinning include distinctive marks occuring in the 4th and 5th stages: gut morphology, position of cervical papillae, excretory opening, morphology of the caudal part of the female. For L4, generic characteristics have not been distinguished (except Petrovinema spp.). Larvae of small Strongylinae species are similar to those of Cyathostominae.

摘要

本文讨论了微小杯环线虫、双齿杯四线线虫、小杯状彼得罗线虫、辐射杯环线虫、三叉杯环线虫、真肛杯齿线虫、梅氏杯齿线虫、蒙古杯齿线虫、不等齿杯口线虫、头状杯首线虫和尖尾杯圆线虫L4期的形态。这些物种按照引言中概述的新系统命名。鉴定在第4次蜕皮期间死亡幼虫的标准包括在第4和第5阶段出现的独特特征:肠道形态、颈乳突位置、排泄孔、雌虫尾部形态。对于L4期,尚未区分属的特征(彼得罗线虫属除外)。小型圆线亚科物种的幼虫与杯口亚科的幼虫相似。
