Naushonia draconis sp nov., a heavily armoured mud shrimp from the Caribbean Sea, and taxonomic status of Espeleonaushonia Juarrero & Maritnez-Iglesias, 1997 (Decapoda: Gebiidea: Laomediidae)

The diagnostic characters of the laomediid mud shrimp genus Espeleonaushonia Juarrero & Martinez-Iglesias, 1997 are reassessed and the genus is synonymized with Naushonia Kingsley, 1897. A new species of Naushonia is described based on a single male collected at a depth of 16 m off the coast of Guadeloupe, French Antilles. Naushonia draconis sp. nov. is closest to two species of Naushonia formerly placed in Espeleonaushonia, namely Naushonia palauensis (Alvarez, Villalobos & Iliffe, 2010) comb. nov. and Naushonia augudrea (Juarrero & Garcia, 1997) comb. nov., but can be separated from both of them and all other species of Naushonia by the high mid-dorsal carina, a row of very strong spines on the lateral surface of the carapace, and prominent mid-dorsal crests on the first, second and third pleomeres. A key to all known species of Naushonia is provided.
