Etymology: Batasio: Malabar voice as the name of the fish (Ref. 45335); feruminatus: The specific name is derived from the Latin ferumino, meaning to weld, and by extension to cement, to join, to unite or to bind, referring to the contact between the dorsal and adipose fins unique to this species within the genus.

Short description
Identification keys | Morphology | Morphometrics
Batasion feruminatus is distinguished from all congeners in having the base of the adipose fin in contact with (vs. separate by a distance of 4.4-23.3% SL) the base of the last dorsal-fin ray and in having a color pattern on the body consisting of both an oblique predorsal bar and a thin midlateral longitudinal black stripe. The contact between the dorsal and adipose fins is also reflected in the longer adipose-fin base in B. feruminatus compared to congeners (39.7-41.6% SL vs. 14.5-35.1). The only other species of Batasion with a longitudinal black stripe on the body are B. batasio and B. macronotus, but both these species lack the black oblique predorsal bar of B. feruminatus. Other species of Batasion in Myanmar with the oblique bar are B. dayi, B. elongatus and B. fluviatilis, but all these species lack the longitudinal black stripe of B. feruminatus (Ref. 74340).
