We placed this new genus, <i>Thailandorchestia</i> <b>gen. nov.</b>, within the family Protorchestiidae. The new genus can be distinguished from the remaining genera by uropod 1 outer ramus with robust setae, uropod 2 outer ramus without robust setae, and pereopod 7 basis without a posterodistal lobe. The type species of <i>Thailandorchestia</i> <b>gen. nov.</b>, <i>Thailandorchestiarhizophila</i> <b>sp. nov.</b>, is described herein, and an updated key to the genera of the family Protorchestiidae is provided.ZooKeys139-153https://www.ebi.ac.uk/biostudies/studies/S-EPMC9848770biostudies-literature<i>Thailandorchestiarhizophila</i> sp. nov., a new genus and species of driftwood hopper (Crustacea, Amphipoda, Protorchestiidae) from Thailand.PMC9848770Wongkamhaeng KDumrongrojwattana PSumitrakij RKeetapithchayakul TSfalse<i>Thailandorchestiarhizophila</i> sp. nov., a new genus and species of driftwood hopper (Crustacea, Amphipoda, Protorchestiidae) from Thailand.During a scientific survey, a new genus of driftwood hopper was found in mangrove roots in Ko Kut District, Trat Province, Thailand.
