Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 8; Raios dorsais moles (total) : 9 - 10; Raios anais moles: 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).

Tornabene, L., J.L. Van Tassel, D.R. Robertson and C.C. Baldwin, 2016. Molecular phylogeny, analysis of discrete character evolution, and submersible collections facilitate a new classification for a diverse group of gobies (Teleostei: Gobiidae: Gobiosomatini: Nes subgroup), with descriptions of nine new species.
