Status of Exosphaeroma inornata Dow and E. media George and Stromberg (Isopoda: Sphaeromatidae) with Ecological Notes

Résumé fourni par la source

The sphaeromatid isopod Exosphaeroma media George and Stromberg 1968 from San Juan Island, Puget Sound, is synonymized with E. inornata Dow 1958 from California. Differences between the original descriptions of both species are attributed to author errors or variations in the phenotype. Variation in the relative position of the rostrum and clypeus, crenulation of the uropod rami, pleotelson shape, coxal plate suture lines, and body ratio (width/length) are discussed. Exosphaeroma inornata is reported to be a wide-ranging intertidal species which is commonly found in crevices, sand, and associated with various algae. Although the distribution is reported to be from San Diego, Calif., north to San Juan Island, Puget Sound, a large distribution gap exists between Humboldt Bay and Puget Sound. Key words: isopod synonomy, anatomical variations, distribution, habitat
