简单描述
型态特徵 | 形态测量图
臀鳍软条: 8; 脊椎骨: 27. This species can be distinguished by the following set of characters: D1 fin with small filaments extending beyond membrane on spine tips, spines 2-4 nearly equal; D2 I,9; A I,8; P 17, rays 14-15 elongate extending to a vertical through 5th second dorsal-fin ray, past the anal origin to vertical through anal rays 4-5; pelvic fins well separated, all rays unbranched without flattened fleshy tips, long ray extending past anus to anal fin origin; no scales on body of preserved specimen, though small embedded ctenoid scale at D1 fin base; modified basicaudal scales present; papillae rows 5s and 5i connected as a continuous transverse row; interorbital papillae row pc’ and pe’ present; no cephalic lateralis pores on head or preopercle; single anal fin pterygiophore inserted anterior to haemal arch; presence of 7 black stripes from below eye to caudal peduncle (Ref. 113825).
Collected on the shore from a steep rocky slope (45° slope) with thin and sparse calcareous Halimeda rubble layer, mixed with interspersed flat rock outcroppings, hard rock unlayment and scattered rock boulders ca. 1 to 30 m in diameter (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. Zoological Journal of the Linnean Society 177(4):764-812. (Ref. 113825)
