( Fig. 2A View Fig )

Material examined. Chichi-jima Is. — Hitomaru-jima I. (27°06′57″N, 142°11′14″E), 6–8 m, 1 juv. (NSMT-Cr 31510; cb 3.2×cl 2.7 mm), 29-VI-2014, T. Akiyama leg. GoogleMaps

Remarks. The specimen at hand is juvenile, but the identification was based on its fine color photograph ( Fig. 2A View Fig ) that agrees well with the color photograph of the holotype (Trautwein, 2007, fig. 4A–B). This species is most close to Tetralia nigrolineata which was originally named T. glaberrima forme nigrolineata by Serène and Pham (1957) and later treated as a full species, T. nigrolineata by Galil (1988), and also similar to some related species in having the brackishcolored front and anterior part of the carapace anterolateral margins, with a bluish transverse line behind the frontal margin. Among the species having such type of carapace coloration, however, this species is characteristic in having some longitudinal bands of pinkish or brick reddish color on each segment of the ambulatory legs.

Distribution. This species was originally described based on many specimens from Guam (Mariana Is.), Okinawa (Ryukyu Is.), and Moorea (Society Is.), and recently, Maenosono (2017) reported this species from some local places in Okinawa-jima Island.
