Stolephorus teguhi sp. nov. is described from the holotype and 14 paratypes, 49–77 mm in standard length, collected from North Sulawesi, Indonesia. The species is characterized by having numerous gill rakers (31–35 + 41–46 = 72–82) and a short upper jaw, its posterior tip reaching to or extending slightly beyond the anterior margin of the preopercle. Stolephorus pacificus and S. multibranchus also have relatively numerous gill rakers for species of this genus (21–27 + 29–36 = 53–61 and 21–28 + 30–35 = 54–60, respectively), but counts for S. teguhi exceed those for the two species. Although S. advenus also has a short upper jaw similar to that of S. teguhi, the former has far fewer gill rakers (19 + 24 = 43) than the latter.
