Distribution. Japan (Ryukyu and Izu Islands) and Australia; 10–61 m ( Asakura 2000; Osawa & Takeda 2004).

Habitat. Coral reefs, often in rocky areas or submarine caves ( Kato & Okuno 2001; Osawa & Takeda 2004).

Remarks. Pylopaguropsis speciosa has been often recorded from coral reefs including submarine caves in the Ryukyu Islands ( Asakura 2000; Osawa & Takeda 2004; Osawa & Fujita 2016; Table 2). The coloration of the species is very characteristic and readily distinguished from other congeners; the right chela is magenta and the left cheliped and ambulatory legs are bright orange with white stripes ( Fig. 3E ).
