6B0557602418FFCB1CF4A886FAC6C13C.taxon	etymology	Etymology: This genus is dedicated to the paleontologist Maria Somália Sales Viana, in recognition of her extensive contributions to the studies of geology and paleontology of the Araripe Basin, as well as Brazilian fossils. Gender feminine.	en	Barros, Olga Alcântara, Oliveira, Paulo Victor De (2023): New Dendrobranchiata fossil preserved in the Brazilian Cretaceous (Aptian / Albian) from the Araripe Basin, Piauí State.

6B0557602418FFCB1CF4A886FAC6C13C.taxon	diagnosis	Diagnosis: Carapace with antennal and branchiostegal spines. Long rostrum, with thirteen evident dorsal spines yielding a serrate appearance. Laminar scaphocerite large, lateral margin weakly rounded, longer than rostrum. Pleura of second pleonal somite overlapping the third but not the first. First and second pleonal somites approximately the same size, the third slightly larger, and the fourth and fifth approximately the same size. Sixth somite elongated and approximately twice the length of the previous somites. Telson smaller than uropods, with the lateral margin weakly rounded.	en	Barros, Olga Alcântara, Oliveira, Paulo Victor De (2023): New Dendrobranchiata fossil preserved in the Brazilian Cretaceous (Aptian / Albian) from the Araripe Basin, Piauí State.

Type locality: municipality of Caldeirão Grande do Piauí, Piauí State. Stratigraphic unit: Romualdo Formation, Santana Group, Araripe Basin. Age: Early Cretaceous-Albian	en	Barros, Olga Alcântara, Oliveira, Paulo Victor De (2023): New Dendrobranchiata fossil preserved in the Brazilian Cretaceous (Aptian / Albian) from the Araripe Basin, Piauí State.

6B0557602419FFC81CF4AE8AFE54C549.taxon	etymology	Etymology: The specific epithet was derived from the locality where the material was collected. It derives from the state of Piauí, northeast Brazil, and this choice was due to this being the first record of fossil shrimp occurrence in this region of the Araripe Basin.	en	Barros, Olga Alcântara, Oliveira, Paulo Victor De (2023): New Dendrobranchiata fossil preserved in the Brazilian Cretaceous (Aptian / Albian) from the Araripe Basin, Piauí State.

Second part of the pereiopods scarcely preserved and with a chelate appearance, pleopods on the second somite poorly laterally preserved, the third to fifth not preserved. Pleon laterally compressed, six-segmented, all somites without spines. Pleura of the second pleonal somite overlapping with the third but not the first; the first and second somites approximately the same size, the third slightly larger, and the fourth and fifth somites approximately the same size; the sixth somite elongated and approximately twice the length of the previous somites. Telson smaller than uropods, the lateral margin weakly rounded.	en	Barros, Olga Alcântara, Oliveira, Paulo Victor De (2023): New Dendrobranchiata fossil preserved in the Brazilian Cretaceous (Aptian / Albian) from the Araripe Basin, Piauí State.
