Stenopodidean shrimps are mostly cryptic in their habitats and are typically related with coral rubble or dead coral heads, rocks and crevices, and in association with other marine invertebrate such as sponges, crinoids and corals.Here, we describe a new stenopodidean shrimp, Dubiostenopus parvus n.gen.n.sp.

, from the Romualdo Formation (Aptian/Albian), Araripe Sedimentary Basin.The specimen studied here was collected in the municipality of Trindade, Pernambuco State, Grains Brazil.The specimen is the imprint of a small shrimp approximately 10 mm in length, with a robust cephalothorax, a well-developed cheliped in the third pereiopod, and a second pleura not overlapping the first.This is the first stenopodidean shrimp described from the Romualdo Formation and the first described from South America.Comparisons with other Brazilian shrimp-like fossils RED are made, as well as comparisons with all other fossil stenopodideans.
