Odontozona edwardsi, a rare stenopodid shrimp from deep waters of the northwest African coast off Morocco and Western Sahara is redescribed and figured based on type material and an additional 26 specimens including some from the Gulf of Cadiz and off Roscoff, France. Specimens of another Odontozona from the Gulf of Mexico, off Sapelo Island, Georgia, and off Rio de Janeiro, Brazil have been confused with O. edwardsi and O. spongicola. This Odontozona is associated with the deep sea hard coral Lophelia pertusa and is herewith designated as a new species. Both these Atlantic species of Odontozona are distinguished from the deep-water Pacific O. spongicola as well as the recently described southwestern Atlantic O. meloi by several morphological characters. A key to the Atlantic species of Odontozona is presented.
A review of the genus Engystenopus (Crustacea: Decapoda: Stenopodidea) Juxtastenopus, gen. nov. , a new combination for E. spinulatus Holthuis, 1946, and transfer of E. palmipes Alcock & Anderson, 1894 to the family Spongicolidae Schram, 1986* Abstract A review of the genus Engystenopus is presented. A new genus, Juxtastenopus, is created for the rare deepwater stenopodid shrimp, Engystenopus spinulatus based on a series of specimens from the Red Sea, Gulf of Aden and the Philippines. The genus Engystenopus is now restricted to E. palmipes, its range is extended to Australian, Indonesian, and Madagascan waters, a new diagnosis of the genus is presented, and the genus is transferred to the family Spongicolidae. This paper summarizes the morphology of 27 specimens of E. spinulatus and transfers the species to a new genus Juxtastenopus of the family Stenopodidae. With the removal of E. spinulatus into the new genus Juxtastenopus, the examination of an additional 22 specimens of E. palmipes, and over 60 species in 13 genera and 3 families for the infraorder Stenopodidea, the closeness of Engystenopus to Stenopus needed to be closely reexamined.

A new species of the stenopodid shrimp Odontozona is described from deep-water off the west coast of Mexico. It is distinguished from the three other species of the genus known in the area, from O. rubra Wicksten, 1982, and O. foresti Hendrickx, 2002, by the absence of a series of spines on the posterior half of the carapace, behind the post-cervical groove, and from O. spongicola (Alcock & Anderson, 1899) by the presence of spines on the ventral margin of somites 1-5 (smooth in O. spongicola) and by the much slender third pair of pereiopods in the new species. A new record is provided for O. foresti, and the first male specimen, the third specimen on record, is compared with the female holotype.
