中文摘要:
      2021年6月在陕西省岚皋县和佛坪县的汉江上游采集到12尾荷马条鳅属,使用电子数显游标卡尺点对点测量可量性状,通过肉眼或借助解剖镜观察可描述性状,采用Micro-CT影像计数脊椎骨。12尾标本体长65.68~95.01mm,标本与模式产地为河南省西峡县鹳河的鹳河荷马条鳅(Homatula guanheensis)完全一致。简要描述了该新纪录种的形态特征。鹳河荷马条鳅在陕西省境内分布的发现,是荷马条鳅属鱼类在该省的新纪录,使得该属在陕西省境内分布的物种数达到5个。提供了陕西省境内的5种荷马条鳅的检索表,并提出了荷马条鳅的保护建议。
英文摘要:
      Homatula, Nemacheilidae, Cypriniformes, is primarily distributed in the rivers of south China. At present, there are 4 species of Homatula recorded in Shaanxi Province, including H. potanini, H. variegata, H. berezowskii and H. laxiclathra. During June 2021, twelve specimens of genus Homatula were collected in a fishery resource investigation in the upper Hanjiang River basin in both Nangao and Foping counties of Shaanxi Province.Then the twelve specimens were identified by measuring the measurable traits using?electronic?digital?vernier?caliper, observing the describable traits using anatomical lens and vertebra counting. The body length of the twelve specimens was in the range of 65.68-95.01mm. Morphological comparisons with congeneric species confirmed that these specimens are conspecifics with Homatula guanheensis, a species originally described from the Guanhe River, which flows into the middle Hanjiang River basin in Xixia County, Henan Province. Apparently, this species has expanded to Shaanxi Province and the discovery of H. guanheensis in Shaanxi Province brings the total species number of Homatula in this province to five. Finally, we briefly described the morphological characteristics of the newly recorded species based on the specimens of H. guanheensis caught from Shaanxi Province, and also provided an indentification key for the five species of Homatula in this province. Also, some suggestions for the conservation of Homatula are proposed, including extensive community surveys and on - site conservation related to the fresh water ecosystem.
