Telphusa austeniana Wood-Mason, 1871 is a poorly known potamid crab described from a single female specimen from Meghalaya state, northeastern India, and its position in Tiwaripotamon Bott, 1970 has been questioned. Its systematic position is now clarified based on the examination of the female holotype and a male specimen recently collected from a cave near the type locality. The species is transferred from Tiwaripotamon to a new genus, Krishnamongen. nov. on the basis of the differences in the structures of the epigastric cristae, male pleon, male sixth pleonal somite, male telson, gonopods, and vulvae. The geographic distributions of the two genera are some 1,000 km apart. The new genus has affinities with Doimon Yeo & Ng, 2007, and Indochinamon Yeo & Ng, 2007, but can be distinguished mainly by its extremely slender and elongated ambulatory legs. While Krishnamon austenianum (Wood-Mason, 1871) comb. nov. is now recorded from limestone caves, it does not, however, possess the troglomorphic features of an obligate troglobite.

克里希纳蒙（Krishnamon），一种来自印度东北梅加拉亚邦（Methalaya）的新蟹类，属澳大利亚海绵螯蟹（Telphusa austeniana Wood-Mason），1871年（十足目：Brachyura：Potamidae）

Telphusa austeniana Wood-Mason，1871年，是一种鲜为人知的波塔米蟹，描述自印度东北部梅加拉亚邦的一个雌性标本，其在1970年的Tiwaripotamon Bott中的地位受到质疑。现在，根据对女性同型体和最近从该类型所在地附近的山洞中收集的男性标本的检查，弄清了它的系统位置。该物种从蒂瓦里普达蒙转移到了新属克里希纳蒙（Krishnamon）属。十一月 根据上cr骨，雄性ple骨，雄性第六个so骨体，雄性telson，性腺和外阴的结构差异而定。两个属的地理分布相距约1,000公里。这个新属与Doimon有亲缘关系Yeo＆Ng，2007年，以及Indochinamon Yeo＆Ng，2007年，但其主要特点是极其纤细细长的动态腿。虽然Krishnamon austenianum（木梅森1871）梳。十一月 现在是从石灰岩洞穴中记录下来的，但是它不具有专性的闪球虫的闪长岩特征。
