Myanmarorchestia victoria sp. nov. (Crustacea Amphipoda Talitridae) a new species of landhopper from the high altitude forests in Myanmar

摘要

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.
