A New Species

We describe Expanathura monile sp. nov. from Iriomote Island, Okinawa, Japan, northwestern Pacific. This species resembles E. collaris, E. macronesia, and E. haddae in having very broad uropodal rami, a broad telson, and a moderately shortened pleopod 1 endopod, but differs from these three species in the female having (1) the head with a dorsal V-shaped band of brown pigmentation, (2) the antennular flagellum with 3–4 articles, (3) antennal peduncular article 2 with an outer triangular projection, (4) the uropodal endopod longer than wide, (5) the uropodal exopod with an acute triangular projection, (6) an oval telson, and (7) the posterolateral setae on the telson similar in length. We present a revised key to known species in the genus Expanathura and briefly discuss the male polymorphism observed in E. monile.

A New Species

The flower bug genus Montandoniola Poppius, 1909 of Japan, which previously was represented by a single species, is herein reviewed. Three species are recognized. A new species, M. kerzhneri sp. nov., is described from Iriomote Island of the Ryukyus. Montandoniola thripodes Bergroth, 1916 is recorded from Japan for the first time. Montandoniola thripodes and M. pictipennis (Esaki, 1931) are diagnosed, with detailed descriptions and illustrations of the male and female genitalia. Digital images of the habitus and external characters are provided for all species. Biological notes on M. thripodes and M. pictipennis and a key to the Japanese species are also given.

A New Species

A new species of aphanodactylid genusAnkeriusNg, Rahayu & Shih, 2016, is described from Iriomote Island, Ryukyu Islands, Japan.Ankerius grusocuraren. 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.

Alpheid Shrimp

A new alpheid shrimp species, provisionally assigned to the genus Salmoneus Holthuis, 1955, is described and illustrated on the basis of three specimens extracted from intertidal soft sediments on seagrass beds at Iriomote Island, southern Ryukyu Islands, Japan. Salmoneus singularis n. sp. is highly distinctive within the genus in having a pair of postorbital spines on the carapace, otherwise showing some affinities to the species of the S. gracilipes Miya, 1972 group. The possession of paired spines on the dorsolateral surface of the carapace is shared with several members of Triacanthoneus Anker, 2010, which is undoubtedly closely related to Salmoneus. However, the new species cannot be placed in Triacanthoneus because of the absence of a mid-dorsal spine on the carapace.
