Abstract

Cyclobulura superinae n. sp. collected from Zaedyus pichiy and Chaetophractus vellerosus is herein described as the second species in Cyclobulura Quentin, 1977, and the first subulurid in armadillos. The species is unique in the spur-like structures present at the tip of both spicules, yet they conform to the description of Cyclobulura in the structure of the buccal parts. Specimens of the new species show longer chordal lobes and more conspicuous radial lobes and are smaller than specimens of C. lainsoni. In addition, males of C. superinae exhibit a spur-like process in the distal end of the spicules and a shorter tail (170 vs. 300 µm) with no spine. Finally, the eggs of C. superinae are smaller (60-89 × 45-71 vs. 95-100 × 80-85). To our knowledge, the new species is the first subulurid nematode found in an armadillo.

摘要

从扎迪乌斯犰狳（Zaedyus pichiy）和毛犰狳（Chaetophractus vellerosus）体内采集到的苏氏环尾线虫（Cyclobulura superinae）新种，在此被描述为1977年昆廷（Quentin）所定环尾线虫属（Cyclobulura）中的第二个物种，也是犰狳体内发现的首个尖尾线虫科（Subuluridae）线虫。该物种独特之处在于两根交合刺尖端均有刺状结构，但其口部结构符合环尾线虫属的描述。新物种标本的弦叶更长，放射叶更明显，且比兰氏环尾线虫（C. lainsoni）的标本更小。此外，苏氏环尾线虫雄虫交合刺远端有刺状突起，尾部较短（170微米对300微米）且无刺。最后，苏氏环尾线虫的虫卵更小（60 - 89×45 - 71对95 - 100×80 - 85）。据我们所知，该新物种是在犰狳体内发现的首个尖尾线虫科线虫。
