Pylopaguropsis bellula Osawa & Okuno, 2007 

( Fig. 3 AView FIGURE 3)

Pylopaguropsis bellula Osawa & Okuno, 2007: 31  , figs. 1–5, 6A, B, 7A, B (type locality: Kume Island, Ryukyu Islands).

Material examined. Ie Island, unnamed submarine cave:  main tube, 7 September 2016, 2 males (sl 2.9, 3.3 mm), 1 ovigerous female (sl 4.6 mm), RUMF-ZC-6041 ( IE 13); main tube, near bifurcation of tube, 7 September 2016, 1 male (sl 4.1 mm), RUMF-ZC-6042 ( IE 17); main tube, near bifurcation of tube, 8 September 2016, 1 male (sl 3.6 mm), RUMF-ZC-6043 ( IE 59). Okinawa Island , Hedo Dome cave : main tube, 11 August 2016, 1 male (sl 2.6 mm), RUMF-ZC-6044 ( HD 2016-67). Shimoji Island, Akuma-no-Yakata cave: entrance, 1 September 2017, 1 male (sl 3.8 mm), RUMF-ZC-6045 ( SH 101).

Distribution. Ryukyu Islands (Ie Island, Okinawa Island, Kume Island, and Shimoji Island) in southwestern Japan; 15–35 m ( Osawa & Okuno 2007; present study).

Habitat. Coral reefs; found in submarine caves and crevices of fore-reef slopes ( Osawa & Okuno 2007).

Remarks. Five species of the genus Pylopaguropsis Alcock, 1905, P. bellula  , P. fimbriata  , P. granulata  , P. keijii  , and P. speciosa  , have been recorded from the submarine caves in the Ryukyu Islands ( Osawa & Takeda 2004; Osawa & Okuno 2007; Osawa & Fujita 2016; present study; Table 2). The dactyli and propodi of the ambulatory legs are solid-colored in P. bellula  and P. keijii  , whereas those of P. fimbriata  , P. granulata  , and P. speciosa  have white stripes ( Fig. 3View FIGURE 3). Although such a solid coloration of the ambulatory legs is also known in another congener P. furusei Asakura, 2000  , it is uncommon and usually striped in other Pylopaguropsis species.
