RESUMO
Hernáez et al. (2020) described a new species of ghost shrimp, Neocallichirus pinheiroi, from northeastern coast of Brazil, Western Atlantic. Although the description and figures presented by Hernáez et al. (2020) fully characterize the new species, the journal issue in which the description appeared was published online only, and the article in which N. pinheiroi appeared did not include a ZooBank registration number (LISD), required for validation of new names in electronic-only publications [vide Art. 8.5.3 of the amended Code of the International Commission on Zoological Nomenclature (ICZN, 1999, 2012)]. As result, the name Neocallichirus pinheiroi Hernáez, Windsor, Paula Santana, 2020, is not available according the International Code of Zoological Nomenclature (ICZN, 1999, 2012). Therefore, the present note serves to validate the name Neocallichirus pinheiroi by fulfilling the ICZN conditions for nomenclatural availability.

A new species of callianassid mud shrimp is described from outer continental shelf waters of the northwestern Gulf of Mexico, where it appears to commonly live in close association with sediments on or near natural hydrocarbon seeps. Recent genus-level taxonomic revisions of the Callianassidae, based on gene sequence analyses and comparative morphological studies, included specimens representing this new species, assigning it with strong support to the genus Pugnatrypaea Poore et al., 2019. The other known species of this genus are also typically found in offshore waters of continental shelves, but are all restricted in distribution to the Indo-West Pacific and are known from relatively few specimens. Collections of this new Gulf of Mexico representative of the genus are all from slightly deeper waters than for other known congeners, and commonly occur near hydrocarbon seeps, on some occasions being directly associated with sulfidic substrates that include waxy crude oil globules.

Glypturus rabalaisae Sakai, 2011 was named for type materials identified solely on the basis of illustrations that had been originally reported as "Glypturus acanthochirus" by previous authors (Rabalais et al. 1981). As the voucher specimens for those illustrations (thus the types) are lost, a neotype is designated. "Glypturus rabalaisae" as originally applied by Sakai (2005) constituted a nomen nudum, and the name has debatably remained so regarded, since the description in Sakai (2011) failed to clearly account for disposition of a type. In the interest of stability, his 2011 description is herewith regarded to meet minimum ICZN requirements for validity, and the name is conserved. Synonymies, brief diagnoses, and updated ranges are provided for Glypturus rabalaisae and its only known regional congener, G. acanthochirus Stimpson, 1866. Available illustrations of G. rabalaisae are augmented by color photographs.
