A new pontoniine shrimp from Cape Verde Islands, Pseudocoutierea wirtzi sp. nov. is described here from specimens collected on the gorgonian Leptogorgia gaini Stiasny, 1940 and the antipatharian Stichopathes lutkeni Brook, 1889. This is the first record of the genus Pseudocoutierea Holthuis, 1951 in the Eastern Atlantic. P. wirtzi sp. nov. has a blunt protuberance on the hepatic/ postorbital area, which is lacking in the previously described Pseudocoutierea species. In the new species, the last three pairs of pereiopods have a large subdistal swelling on their merus. The proximal surface of these swellings is decalcified and their internal tissue is granular. It is not impossible that these structures are of glandular nature. The new pontoniine shrimp is briefly compared with other related or possibly related genera and species. Some previously overlooked but important morphological characters of the distantly related species Balssia gasti (Balss, 1921) are also described and illustrated here
