ABSTRACT

Dynoides canadensis sp. nov. is described from the south-western coast of British Columbia, Canada. This species differs from its closely related species, D. elegans (Boone, 1923) ), by the presence of a smooth pleotelson without prominent rounded tubercle on the basal part of the pleotelsonic sinus, its sinus wall lacking crenulation; in having the penial processes length 7.7 × basal width and acute distal apex instead of 2.3 × basal width and rounded and blunt distal apex in D. elegans. This new species also has an appendix masculina with the distal apex extending somewhat beyond its base, instead of not reaching the base as is the case for D. elegans. A map of the distribution for the north-eastern Pacific species of Dynoides Barnard, 1914 (D. elegans (Boone, 1921); D. crenulatus and D. saldanai Carvacho & Haasmann, 1984; and D. dentisinus Shen 1929) in the north-eastern Pacific is provided. The new species is abundant in the western coastal zone of British Columbia. A revised generic diagnosis is provided for the genus Dynoides.

摘要

Dynoides加拿大一枝黄花属。十一月 描述于加拿大不列颠哥伦比亚省的西南海岸。该物种与其紧密相关的物种D. elegan s（Boone，1923）的不同之处在于，在胸膜软骨窦的基部存在平滑的胸膜腔，而没有明显的圆形结节，其窦壁缺乏细齿状。线虫的阴茎长度为7.7×基础宽度和急性远端尖，而不是2.3×基础宽度和圆形钝的远端顶点。这个新物种也有一个阑尾假肢，其远端先端有点超出其基部，而不是像线虫一样没有到达基部。东北太平洋Dynoides物种分布图巴纳德，1914（D.线虫（布恩，1921）; D. crenulatus和D. saldanai Carvacho＆Haasmann，1984;和D. dentisinus沉1929）在东北地区被提供。新物种在不列颠哥伦比亚省的西部沿海地区丰富。修订的通用诊断提供了Dynoides属。
