The new species is compared to known fossil palaemonids found in Brazil. Kellnerius jamacaruensis n. gen. n. sp. is easily differentiated from the other palaemonids by a rostrum with 5 spines, an enlarged scaphocerite that is longer than the rostrum, and a third somite with a distinct groove in the tergite that does not extend to the pleurite.293-300engFossils concretionsPalaemonidaeSantana groupCrato formationArtigo10.11646/zootaxa.3620.2.7Acesso restrito
