Etymology: Trigonognathus: Greek, trigono = a triangle + Greek, gnathos = jaw (Ref. 45335). Refers to the triangular shape of the jaws (Ref. 31259); kabeyai: Named after Mr. Hiromichi Kabeya who collected the type specimens (Ref. 31259).
Eponymy: Hiromichi Kabeya was captain of the trawler ‘Seiryo-Maru’ from which the holotype was caught (1986). He was still master of the vessel in 2006. (Ref. 128868), visit book page.
