Abstract

Abstract: A new nematode, Cosmocercoides minshan n. sp. (Cosmocercidae) is described from Bufo minshanicus in the Zoige grassland in southwestern China. The new species is characterized as a medium-sized worm (4.93–7.97 mm in length and 0.24–0.47 mm in width), but with a shorter spicule length (0.08–0.21 mm) than other Cosmocercoides, with lateral alae and 9 pairs of caudal papillae. Among the 21 recorded species in this genus, the morphology of the new species is different from all the other species previously reported. DNA sequences of C. minshan sp. showed that the species is almost identical to Cosmocercoides pulcher (99%), and Cosmocercoides tonkinensis (99%). However, there are differences in the morphology and structure of the rosetted papillae among these 3 species, as well as 4 nucleotide differences in the 18S–28S rDNA including the internal transcribed spacer region. In a neighbor-joining phylogenetic tree, C. tonkinensis, C. pulcher, and C. minshan formed a robust clade. Generally, the species is distinguished molecularly and morphologically; thus C. minshan is herein described as a new nematode species of Cosmocercoides.

标题中国西南布蟾蜍线虫一新种

摘要/ Abstract摘要:在若尔盖草原岷山Bufo minshanicus中发现了一种新线虫Cosmocercoides minshan n. sp. (Cosmocercidae)。该新种体型中等(长4.93 ~ 7.97 mm，宽0.24 ~ 0.47 mm)，但其针尖长度(0.08 ~ 0.21 mm)短于其他Cosmocercoides，具有侧翼和9对尾端乳头。在该属21个记录种中，该新种的形态不同于以往报道的所有其他种。minshan c.m nshan sp.的DNA序列表明，该物种与Cosmocercoides pulcher(99%)和Cosmocercoides tonkinensis(99%)几乎相同。然而，这3个物种的莲座状乳头形态和结构存在差异，18S-28S rDNA包括内部转录间隔区有4个核苷酸差异。在相邻联结的系统发育树上，东kinensis, C. pulcher和C. minshan形成了一个健壮的分支。一般来说，物种是在分子和形态上区分的;因此，本文将岷山线虫描述为宇宙尾球纲线虫的一新种。

期刊介绍： Comparative Parasitology (continuing the Journal of the Helminthological Society of Washington in its 67th volume) focuses on parasitological research of a comparative nature, emphasizing taxonomy, systematics, ecology, biogeography, evolution, faunal survey, and biological inventory within a morphological and/or molecular context. The scope of Comparative Parasitology extends to all parasitic faunas, including helminths, protistans and arthropods.
