Artotrogidae Brady, 1880 is a cosmopolitan family with 23 valid genera and 131 known species. However, a considerable number of these species were subject of reexaminations and redescriptions recently. With the crescent number of new species discovered, it is becoming possible to better understand their boundaries. This study presents a new genus and species of Artotrogidae, recovered from unidentified hosts in debris of benthonic samples from Todos-os-Santos Bay, northeastern coast of Brazil. Kuayguara etymatee gen. et sp. nov. exhibits an underdeveloped first leg, which possess an unsegmented protopod and 1-segmented exopod, a unique set of morphological characteristics that differentiates it from all other genera of the family. Key words: Invertebrate associate, Symbiotic copepods, Systematics, Uncommon leg, Taxonomy
