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.

A new species of stenopodid shrimp of the genus Stenopus, S. goyi, is described on the basis of material from Taiwan, Philippines, Sri Lanka and the Maldive Islands. The new species is very unusual in that the dactyli of the fourth and fi fth pereopods bear one to three ungues. The colouration of the new species is also unique in the genus. The uniunguiculate or biunguiculate dactyli of the ambulatory pereopods were generally considered as a constant character in stenopodid shrimps and are used for generic diagnosis in the family, but variations in the number of ungues are found in S. goyi, new species, sometimes even among pereopods of the same specimen. The genus Stenopus is rediagnosed to accommodate the new species. Revised keys to the genera of Stenopodidae and species of Stenopus are provided.
A new genus, Globospongicola, is established for two new species of deep-water spongicolid shrimps, G. nudibranchus n. sp. from Indonesia and G. spinulatus n. sp. from Vanuatu and New Caledonia. The new genus is distinctive in having simple gills completely lacking lamellae or filaments, instead of typical trichobranchiate gills in all other species in the family. Furthermore, the reduced armament on the body and third pereopod separates the new genus from Microprosthema, Paraspongicola, and Spongicola; the well-developed exopod of the third maxilliped distinguishes the new genus from Spongicola, Spongicoloides and Spongiocaris. The two new species can be distinguished from one another by the shape and armature of the rostrum, the spination of the carapace, the shape of the sixth abdominal somite, the shape of the antennal scale, and the armament of the third pereopods and pleopods of male.

A new species of shrimp in the genus Stenopus collected from off Queensland, Australia, is described and figured. Specimens have been collected from two widely separated locations on the Great Barrier Reef, at Heron Island to the south and Wheeler Reef northeast of Townsville. A preliminary diagnosis and colour plate of another Stenopus from Australia, S. cyanoscelis, was presented by . Recent collections of additional specimens of S. cyanoscelis from Indonesia and Kenya allow a detailed redescription of the holotype and morphological variation within the species. Both the new species, Stenopus chrysexanthus and S. cyanoscelis, are closely related to two Atlantic species, S. spinosus and S. scutellatus. However, both species are easily distinguished by differences in morphology and colour pattern. A key to the eight described Indo-West Pacific species of Stenopus is presented.
