Remarks. In spite of its small size, this species has been recorded many times, with figures, in the papers concerning the coral reefs. The carapace dorsal surface ( Fig. 1C View Fig ) is ill-defined, and the anterolateral margin is regularly convex without indentation, differing from the close relative, L. harmsi ( Balss, 1934) , in which each carapace anterolateral margin is divided into four lobes ( Fig. 4D View Fig ). Guinot (1964: fig. 36) finely represented the G1 with some long hairs at the terminal part, and the same figure was reproduced by Serène (1984, fig. 174). Fine figures were given by Dana (1855, as Actaeodes ?), Rathbun (1907, as Actumnus ), Klunzinger (1913), Edmondson (1962) and Takeda (1972). Pseudozius coralliophilus Borradaile, 1902 , and Chlorodiella asper Edmondson, 1925 , are known to be synonymous with this species.

Distribution. Whole Indo-West Pacific waters, from the Red Sea and the western Indian Ocean to the Tuamotu Islands, the Hawaiian Islands and Japan in the Pacific Ocean. In the Ogasawara Islands, this species is previously recorded from Kita Harbor, Haha-jima I. (cf. Takeda and Komatsu, 2023, in list).
