摘要: 记述了采自缅甸维多利亚山高海拔地区的跳钩虾一新种,维多亚跳钩虾Myanmarorchestia victoria sp.nov.。该种的鉴别特征为:颚足触须窄;第二腮足雌雄异型,雄性第二腮足膨大成螯状,雌性第二腮足指状;第二尾肢雌雄异性,雄性第二尾肢外肢末端具小齿,雌性第二尾肢外肢具三个末端刺。形态学比较,DNA条码研究和生态位分析都支持该物种为一新种。

Abstract: Myanmarorchestia victoria sp. nov. is described from high altitude habitats in Myanmar. The new species differs morphologically from its congeners by palp of maxilliped narrow; sexually dimorphic gnathopod Ⅱ, propodus of male chelate and propodus of female mitten-shaped; and dimorphic uropod Ⅱ, outer ramus of male with small teeth distally, outer ramus of female with three distal spines. Analysis of DNA barcode sequences and niche distinctiveness support recognition of the new species.
