Aniculus retipes Lewinsohn, 1982: 76, figs. 1, 2 (type locality: Mersa Bereika, Sinai Peninsula).— Forest 1984: 51, figs. 13, 20, 51–58.—McLaughlin et al. 2007: 103, 2 unnumbered figs.— Poupin et al. 2013: 26, fig. 13B.

Material examined. Ie Island, unnamed submarine cave:  entrance, roof, 23 June 2017, 1 male (sl 11.9 mm), RUMF-ZC-6006 (IE141). Okinawa Island, Hedo Dome cave: entrance, 5 m from entrance, roof , 10 August 2016  , 1 male (sl 9.1 mm), RUMF-ZC-6007 ( HD 2016-47); entrance, 5 m from entrance, rocks, 10 August 2016, 1 male (sl 7.1 mm), RUMF-ZC-6008 ( HD 2016-49); main tube, 21 May 2017, 1 female (sl 17.0 mm), RUMF-ZC-6009 (HD 2017-83); same data as RUMF-ZC-6009  , 1 male (sl 13.6 mm), RUMF-ZC-6010 (HD 2017-94). Shimoji Island, Akuma-no-Yakata cave: middle zone, roof , 6 February 2017  , 1 female (sl 12.7 mm), RUMF-ZC-6011 ( SH 55).

Distribution. Wide ranging in the Indo-West Pacific: Red Sea, eastern Africa ( Tanzania), Glorioso Islands, Christmas Island, Cocos (Keeling) Islands, Indonesia, Vietnam, Taiwan, Japan, eastern Australia, Solomon Islands, Wallis, Futuna, Samoa, and French Polynesia; 0–35 m (McLaughlin et al. 2007; Poupin et al. 2013; present study).

Habitat. Coral and rocky reefs ( Nomura et al. 1996; Poupin et al. 2013).

Remarks. Two species of the genus Aniculus Dana, 1852, A. maximus Edmondson, 1952 and A. retipes, have been recorded from submarine caves in the Ryukyu Islands ( Rahayu & Osawa 2012; Osawa & Fujita 2016; Table 2). In general, A. retipes is more commonly found in cryptic environments of coral reefs than A. maximus.
