摘要

摘要: 该文描述了一种来自中国广西野鲮亚科的一新属新种，才劳桂墨头鱼（Guigarra cailaoensis）。该物种可通过一系列的形态特征与其他属相区分：（1）吻皮光滑，后缘轻微的分裂；（2）上唇发育良好并且盖住大部分上颌；（3）具有吸盘，吸盘前缘有一个新月形皮质条；（4）吸盘的皮质条和游离后缘与肉垫之间的边界不明显；（5）吸盘后缘没有缺刻。同时基于三个基因的分子系统发育分析表明该种与盘鮈属（Discogobio）和盘口鲮属（Discocheilus）的关系最近。形态学和分子系统发育分析都支持该物种新属地位的有效性。

Abstract: Guigarra cailaoensis sp. nov. , a new genus and species of Labeoninae, was collected from Guangxi Zhuang Autonomous Region, China. It differs from all other genera within Labeoninae by a unique combination of the following characters: (1) rostral cap smooth with posterior margin slightly serrated; (2) upper lip well developed and covering most of upper jaw; (3) gular disc present with crescentic torus, not forming horseshoe shape; (4) boundaries of torus, labrum, and pulvinus on gular disc inconspicuous; (5) posterior edge of labrum free, without notch. Molecular phylogenetic analysis of three gene datasets indicated that the new genus formed a monophyletic clade and was closely related to Discogobio and Discocheilus. Both morphological and molecular phylogenetic analyses indicated that Guigarra cailaoensis sp. nov. differs from all known labeonin genera and is thus described here as a new genus and species.
