(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).
