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.

Hier wird eine neue Art der Gattung Ankerius Ng, Rahayu & Shih, 2016 [Aphanodactylidae] beschrieben, welche auf der Insel Iriomote, Ryukyu-Inseln, Japan gesammelt wurde. Ankerius grusocurare n. sp. unterscheidet sich von der einzigen weiteren Art dieser Gattung, A. aenigmaticus, durch die Form der Lateralkante der Stirn (= Supraorbitalzahn), durch einen proportional breiteren Carapax und die kleinere Anzahl an Zähnen entlang des oberen Flexor-Randes der Laufbein-Meri. Diese Studie erhöht die Zahl der Aphanodactylidae auf 13 Arten.
