Dorsale stekels (totaal) : 8; Dorsale zachte stralen (totaal) : 9 - 10; Anale zachte stralen: 7 - 8. This species can be distinguished by the following set of characters: D1 VII, without elongate spines; D2 I, 9-10; A I, 7-8; pelvic fins well separated, no anterior frenum, membrane connecting 5th pelvic-fin rays absent or very low; 5th pelvic ray unbranched and 1/2 length of fourth; no without fleshy tips in pelvic-fin; side of body and head without scales; no modified basicaudal scales present; papillae row 5s and 5i connected forming a single row, interorbital papillae row pc’ present; head and preopercle canals and pores absent; two anal-fin pterygiophores inserted anterior to haemal arch. Colouration: reticulating yellowish orange pattern on the body (Ref. 113825).
Found in back-reef rubble habitat. Collected from a sand and rubble (ca. 0.5-10.0 cm in diameter) substrate, 45-90 m from the gradual reef drop-off. Found in or near yellowhead jawfish (Opistognathus aurifrons) burrows. Although not a common species, this species is regularly seen from April to November, which is when jawfish are abundant (Ref. 113825).
