( Figs. 1D , 4 A–D)

Catapaguroides foresti McLaughlin, 2002b: 499 , fig. 1 (type locality: Guam).—Komai et al. 2010: 38, fig. 5B. Catapaguroides kasei Osawa & Takeda, 2004: 1121 , figs. 8–10 (type locality: Ie Island, Ryukyu Islands).

Material examined. Ie Island, unnamed submarine cave: main tube, 9 September 2016, 1 male (sl 1.8 mm), RUMF-ZC-6022 ( IE 65 #, addition); entrance, 24 June 2017, 1 male (sl 2.0 mm), RUMF-ZC-6023 ( IE 173 ); right hall, 24 June 2017, 1 male (sl 1.5 mm), RUMF-ZC-6024 ( IE 184 ). Okinawa Island , Hedo Dome cave: silty room, 22 May 2017, 1 male (sl 1.1 mm), RUMF-ZC-6025 ( HD 2017-108).

Distribution. Guam and southern Japan (Kochi Prefecture, Okinawa Island, and Ie Island); subtidal to 30 m (Komai et al. 2010; present study).

Habitat. Coral reefs; often found in submarine caves (Komai et al. 2010).

Remarks. Komai et al. (2010) synonymized C. kasei Osawa & Takeda, 2004 with C. foresti . Catapaguroides foresti and C. longior , both collected by the present investigations, have similar coloration in general ( Fig. 1D, F, G ), but their morphologies are very different (see Remarks under C. longior ).
