ANKERIUS GRUSOCURARE, A NEW SPECIES OF APHANODACTYLIDAE (DECAPODA, BRACHYURA) FROM IRIOMOTE ISLAND, RYUKYU ISLANDS, JAPAN

摘要

A new species of aphanodactylid genus Ankerius Ng, Rahayu & Shih, 2016, is described from Iriomote Island, Ryukyu Islands, Japan. Ankerius grusocurare n. sp. is distinct from the only congener, A. aenigmaticus, by the shape of the lateral corner of the front (= supraorbital tooth), proportionally wider carapace, and the fewer number of the teeth along the upperflexor margin of the ambulatory meri. The present study brings the number of aphanodactylid taxa to 13 species.
