A new western Atlantic species ofEurysquilla(Crustacea: Stomatopoda: Eurysquilloidea) with a key to the world species

Abstract

A new species of eurysquilloid stomatopod,Eurysquilla petronioisp. nov., is described from the tropical western Atlantic.Eurysquilla petronioisp. nov. is the fourteenth species of the genus to be recognized worldwide, the fifth species from the western Atlantic and the second from Brazilian waters. It is most closely related toE. maiaguesensisfrom Puerto Rico, but differs chiefly in having an unarmed versus apically spinous rostral plate and 6 or 7 rather than 8–10 teeth on dactylus of raptorial claw. A key to the species of the genus is provided.

The Leopard Mantis Shrimp, Ankersquilla pardus, a new genus and species of eurysquillid from Indo-West Pacific coral reefs

“…The mantis shrimp superfamily Eurysquilloidea Manning, 1977, with the single family Eurysquillidae Manning, 1977, contains six genera and 32 species, the majority of which occur in the Indo-West Pacific (Ahyong, 2001, Ahyong, 2010Lucatelli et al, 2013). Eurysquillidae was originally assigned to the Gonodactyloidea Giesbrecht, 1910, based on the ovate maxilliped 3-5 propodi and possession of one or two intermediate denticles on the telson (Manning, 1980;Ahyong, 1997a), but was shown to be outside of the gonodactyloids and instead formed a clade together with the Parasquilloidea Manning, 1995 (also initially thought to be gonodactyloids) and the Squilloidea Latreille, 1802 (Ahyong & Harling, 2000;Van Der Wal et al, 2017).…”
