Stolephorus falco sp. nov. (Teleostei, Clupeiformes, Engraulidae), a new anchovy from Sumatra, Indonesia

A new anchovy species, Stolephorus falco sp. nov., is described based on three museum specimens collected from northern Sumatra, Indonesia. Although the new species resembles S. baganensis Delsman, 1931, S. dubiosus Wongratana, 1983, S. taurus Hata, Lavoué & Motomura, 2022, and S. tri (Bleeker, 1852) in having a predorsal scute and a spine on the pelvic scute, it differs from all four of these taxa in having a distinctively deeper body, fewer scales on the longitudinal series, and additional differences in a number of other characters.
