Two new species of Chirostylids (Decapoda: Anomura: Chirostylidae) from Tasmania

Abstract

Two new anomuran crustaceans from Tasmania are described and illustrated. Gastroptychus rogeri, new species, is similar to G. hendersoni (Alcock and Anderson, 1899) in the carapace spination but may be distinguished by having very spinose abdominal segments. Uroptychus raymondi, new species, is characterized by the combination of a strong midlateral spine on the carapace, a short, relatively broad antenna! scale, and a short antenna! flagellum, which differentiates the species from U. valdiviae Balss, 1913.
