Abstract

We describe two new species of the freshwater-crab genus Demanietta Bott, 1966 from Tanintharyi (Tenasserim) division, southern Myanmar (Burma), Demanietta liui sp. nov. and Demanietta lenya sp. nov. Demanietta liui sp. nov. is morphologically most similar to D. thagatensis Rathbun, 1904 and D. khirikhan Yeo, Naiyanetr & Ng, 1999; D. lenya sp. nov. appears close to D. manii Rathbun, 1904, D. merguensis Bott, 1966, and D. nakhonsi Yeo, Naiyanetr & Ng, 1999. The two new species are easily distinguished from their most similar congeners in the shape of the external orbital tooth, epibranchial tooth, and male first gonopod. Molecular analysis based on partial mitochondrial 16S rDNA also supports the systematic position of the new taxa.

缅甸南部的淡水蟹螃蟹属Demanietta Bott的两个新物种，1966年（十足目：Brachyura：Potamidae）

摘要

我们描述了淡水蟹属Demanietta Bott的两个新物种，1966年来自缅甸南部（缅甸）的Tanintharyi（Tenasserim）部门，Demanietta liui sp.。十一月 和Demanietta lenya sp。十一月 Demanietta liui sp。十一月 在形态上最类似于D. thagatensis Rathbun，1904和D. khirikhan Yeo，Naiyanetr＆Ng，1999；D.lenya sp。十一月 近似乎D. manii拉思，1904年，D. merguensis博特，1966年，和D. nakhonsiYeo，Naiyanetr和Ng，1999。这两个新物种很容易在外眼眶齿，支气管齿和雄性第一脚足类动物的形状上与它们最相似的同类动物区分开。基于部分线粒体16S rDNA的分子分析也支持了新分类单元的系统定位。
