Based on our reexamination of the 9 specimens including the neotype, Bregmaceros lanceolatus is recharacterized and diagnosed by the following combination of features: caudal fin rounded; scales present on gill cover; dorsal surface of snout unpigmented or with a few chromatophores; isthmus pigmented with punctate chromatophores; two parapophyses on abdominal vertebrae; dorsal rays (D) 65-74; anal rays (A) 67-74; vertebrae (V) 58-61; longitudinal scales (LS) ca. 82-88; principal caudal rays (PC) 16-18; head length (HL)/standard length (SL) 14.0-15.5%; caudal peduncle depth/SL 3.2-4.2%. Based on 27 specimens, B, pseudolanceolatus sp. nov. is described. This species is closely similar to B. lanceolatus, but is diagnosed by the following combination of features: caudal fin rounded; scales present on gill cover; dense concentration of chromatophores on dorsal surface of snout; isthmus colorless; one board-like parapophysis on the last three abdominal vertebrae; D 58-64; A 58-67; V 52-55; LS ca. 68-77; PC 14-16; HL 15.5-18.4% SL; caudal peduncle depth 4.1-5.2% SL. Bregmaceros pseudolanceolatus is known from around the Taiwan Strait, southern East China Sea, South China Sea, Gulf of Thailand, Timor Sea, Arafura Sea, and eastern Bay of Bengal.
