On a new species of freshwater crab, Indochinamon khinpyae, from northern Myanmar (Crustacea, Brachyura, Potamidae)

Abstract

A new species of freshwater crab of the genus Indochinamon Yeo & Ng, 2007 (family Potamidae), is described from highlands north of Myitkyina in Kachin State, Myanmar. Indochinamonkhinpyaesp. n. is distinguished from congeners by its very rugose carapace, broad male pleon and distinctively structured male first gonopod; and is the first potamid species recorded from northern Myanmar.

The complete mitochondrial genome sequence of the mountain crab Indochinamon bhumibol

“…Indochinamon bhumibol; freshwater crab; mitochondrial genome; phylogenetic analysis Indochinamon spp. is a giant mountain crab, which is broadly found in Myanmar, Vietnam, and northern Thailand epically in waterfall and mountain areas (Van et al 2016;Ng & Mar 2018). Indochinamon bhumibol was reported as the biggest freshwater crab in Thailand that has a significant role as a non-polluted water indicator in the freshwater ecosystem and has been considered as one of the endangered species (Thaewnon-Ngiw and Suthamrit 2020).…”

Two new species of freshwater crabs of the genera Eosamon Yeo & Ng, 2007 and Indochinamon Yeo & Ng, 2007 (Crustacea, Brachyura, Potamidae) from southern Yunnan, China

“…Eosamon and Indochinamon are widely distributed in the Indochina Peninsula . Including the two new species described in the present study, Eosamon and Indochinamon respectively contain 12 and 40 species Yeo 2010;Naruse et al 2011Naruse et al , 2018; Van et al 2016;Ng and Mar 2018).…”

“…Remarks. Based on the morphology of G1, Ng and Mar (2018) separated Indochinamon into several groups. The G1 terminal segment of I. malipoense sp.…”

“…In I. khinpyae, the carapace and G1 show considerable variations (Ng and Mar 2018). In smaller individuals, the carapace is less sculptured and the G1 terminal segment is shorter and straighter (Ng and Mar 2018). In I. malipoense sp.…”
