This species is closer to the Platypodia species than the Lophozozymus species especially in the armature of the carapace anterolateral teeth. In life, the carapace dorsal surface is chocolate brown mottled with complex whitish pattern camouflaged to the surroundings. Its color pattern is variable individually, but may be one of the characteristics of this species ( Sakai, 1976 , pl. 144 fig. 2; Kato and Okuno, 2001 , p. 126, 1 unnumbered fig., as Atergatis floridus (Linnaeus) ; Mendoza et al. , 2014 , fig. 4F; Maenosono, 2022c , fig. 10A; present paper, fig. 3G). The carapace dorsal surface is smooth and shallowly separated into regions, with the crested anterolateral margin which is marked with three closed indentations; the last or fourth lobe is small and obtuse, but not isolated from the anterior lobe different from the formation in Lophozoymus . The upper margins of the palms and ambulatory meri, carpi and propodi are strongly crested. Distribution. Widely distributed in the Indo-West Pacific from the Red Sea to the South Pacific and northwards to the Ryukyu Islands.
