Abstract

The Arcitalitridae (Amphipoda, Senticaudata, Talitrida, Talitroidea) is a diverse family containing 15 genera, of which Myanmarorchestia Hou, 2017 and Solitroides Suzuki, Nakano, Nguyen, Nguyen, Morino &amp; Tomikawa, 2017 were reported in Southeast Asia. During research of terrestrial amphipods in Myanmar, we found character traits of some specimens did not match any existing genus of the family Arcitalitridae. These specimens should belong to a new genus.<br> This new genus Kachinorchestia Hou, gen. nov. with one new species Kachinorchestia putao Hou, sp. nov. is described from terrestrial habitats in Myanmar. This new genus is characterised by mandible left lacinia mobilis with four teeth, gnathopod II propodus of male enlarged, oval and subchelate, with hook posteriorly, simplidactylate pereopods, complex and lobed gills and telson uncleft. Photos, molecular and morphological descriptions of new genus are provided.
