Etymology: Gogangra: Perhaps from Greek, goggros, -ou = conger; derived also from the word "goggrone, -es" = goitre + an inclusion of Latin, conger. Look at the similitude goggros/goitre !!; laevis: From the Latin laevis, meaning smooth, in reference to the entrire (unnotched) anteroventral margin of the opercle in this species.

背棘 (總數) : 1; 背的軟條 (總數) : 6 - 8; 脊椎骨: 32 - 35. Distinguished from Gogangra viridescens in having the anteroventral margin of the opercle (the particular facet with the interopercle) gently curved (vs. distinctly notched); narrower head (17.2-20.8% SL vs. 19.7-23.2; 58.2-64.8% HL vs. 65.6-76.9) and larger eye (20.3-24.8% HL vs. 16.2-20.5) (Ref. 55981).
