    摘要:

    副棘鳅属(Paracanthocobitis)隶属于鲤形目(Cypriniformes)条鳅科(Nemacheilidae)，分布范围西起巴基斯坦的印度河流域，东至老挝和柬埔寨的湄公河流域。2022年7月，在我国云南省德宏傣族景颇族自治州盈江县采集到一批副棘鳅属鱼类标本，经形态性状和分子系统比较，确认为曼德勒副棘鳅(P. mandalayensis)，为中国新记录种。本文对中国境内曼德勒副棘鳅进行了形态描述并提供了物种鉴定的分子依据：该种的主要特征为下唇中央部分有一对中断而膨大的片状结构，密布乳突；尾柄基部上缘有一眼状斑；雄性具有眶下沟；侧线完全；腹鳍基部具腋鳞；背鳍有10?分枝鳍条；尾鳍有4 ~ 8条黑色条带。此外，基于系统发育树和间断地理分布推测，曼德勒副棘鳅种内可能存在隐存种，同时对沙副棘鳅(P. botia)中国分布的记录提出了质疑。这一研究为高黎贡山地区的鱼类资源调查和保护提供了科学依据，并对东南亚地区副棘鳅属物种的鉴定提供了新的依据。

    Abstract:

    [Objectives] Paracanthocobitis belongs to Nemacheilidae (Cypriniformes). It is widely distributed from the Indus River basin in Pakistan to the Mekong River basin in Cambodia and Laos. Only one species P. botia,was recorded in China. During July 2022, some loach specimens were collected from Yingjiang County, Dehong Dai and Jingpo Autonomous Prefecture, Yunnan Province. Based on morphological and molecular evidence, they were conspecific with P. mandalayensis, which is a new species record to China. [Methods] In this study, the collected specimens were identified and morphological characteristics were described with reference to research literatures of Paracanthocobitis. Metric traits and vertebrae numbers were measured and counted by electronic vernier calipers and X-ray photography instrument, respectively. Based on COI gene fragments, bayesian inference tree was constructed by Phylosuite 1.2.2 and the genetic distance between individuals of Paracanthocobitis was estimated by p-distance in MEGA X. All new sequences in this study have been uploaded to NCBI GenBank, and other sequences were obtained from NCBI GenBank database (Table 1). [Results] In this paper, our material of P. mandalayensis is fully described, morphological photos (Fig. 1), morphological (Table 2) and molecular (Appendix 1) data for identification are also provided. The main features of P. mandalayensis are papillated pad with median notch on each side of lower lip; a conspicuous black spot (ocellus) close to upper extremity of caudal-fin base; presence of suborbital groove in males; complete lateral line; presence of axillary pelvic lobe; 10? branched dorsal-fin rays; 4﹣8 dark bands on caudal fin. The maximum genetic distance between the collected specimens and individuals of P. mandalayensis in Myanmar is 0.012, while the genetic distances with other species of Paracanthocobitis are 0.129﹣0.189. Therefore, based on morphological and molecular evidences, the specimens in this study are identified as P. mandalayensis. In addition, the minimum genetic distance between the collected specimens and individuals of P. mandalayensis in Thailand is 0.118. There may be cryptic species in P. mandalayensis based on phylogenetic tree (Fig. 2) and disjunction distribution, which also raised questions about the occurrence of P. botia in China. [Conclusion] This study provides a scientific basis for the investigation and conservation of fish resources in Gaoligong Mountain area, as well as new data for the identification of species of genus Paracanthocobitis in Southeast Asia.
