Frontal lamina moderately developed. Coxal plates reduced; oostegite 1 with rounded posterolateral point. Six pleomeres, first five produced into moderately to greatly developed lateral plates; pleopods biramous, lanceolate; uropods usually uniramous, lan‐ ceolate. Male : Body smoothly tapered anteriorly and posteriorly from midpoint (pleon occasionally abruptly wider or narrower than final pereomere) ; all body regions distinct. Pereopods subequal, anterior pereopods not markedly larger than others. Pleon 1/5 to 1/3 of total body length, of six pleomeres (specimens of some species with pleomeres variously fused and pleons proportionately shorter) ; pleopods uniramous, tuberculiform to flaplike; no uropods, posterior border of terminal pleomere slightly to greatly produced into posterolateral points. TYPE SPECIES: Pseudione callianassae Kossmann, 1881 , by monotypy. SPECIES HOSTED BY CARIDEANS: Pseudione affinis (G. O. Sars, 1883 ) , P . ampla Markham, 1988 , P . clevai Boyko, 2004 , P . cognata Markham, 1985 , P . elongata africana Kensley, 1968 , P . elongata elongata ( Hansen, 1897 ) , P . indica Chopra, 1930 , P . magna Shiino, 1951 , P . parviramus Adkison, 1988 , P . pontocari Page, 1985 , P . stylopoda Boyko, 2004 , REMARKS: The remainder of the 53 species and subspecies of Pseudione are parasites of anomurans (26 species), axiideans (10 species), nephropids (3 species), a brachyuran (1 species) and one from an unknown host. The genus is likely paraphyletic, but the type species is very poorly known.
