Comments

Taxonomy from Přikryl et al. 2016.

Genus Diagnosis from Přikryl et al. 2016 (emended after D’Ancona and Cavinato 1965; Houde 1984; Endo 2002; Nelson 2006): "Elongate fish with abdomen shorter than caudal part of body. Nuchal ray present, articulated at posterior part of skull roof. Dorsal and anal fins both subdivided into anterior, middle and posterior sections. Outer rays of pelvic fins elongate. Postcleithrum single, with posteriorly enlarged lamina. Only one palatoquadratal element (ectopterygoid) developed between palatine and quadrate. Vomer toothed. Caudal fin supported by fused hypural plate. Accessory bones X and Y present. Scales cycloid with free termination of circuli at posterior edge of scale. Sagittal otolith large relative to body size."

Species Diagnosis from Přikryl et al. 2016, p. 17: "Bregmaceros species with 10–12 abdominal vertebrae and 36–38 caudal vertebrae. Orbit relatively larger than in B. filamentosus (i.e. orbit length about 1.5 times or greater than the preorbital length). Dorsal fin with 18–19 + 9 + 16–18 rays. Anal fin with 17–19 + 7–8 + 19–21 rays."
