Abstract
Redigobius fotuno sp. nov., described from a limestone sinkhole on Muna Island, Southeastern Sulawesi, Indonesia, is most similar to Redigobius penango (Popta 1922), endemic to the Sulawesi mainland, both species having a robust body and rounded head, reticular body color pattern, and longitudinal suborbital papillae rows. However, the new species is distinguished from the latter in having greater head length (35.3–38.4% of standard length [SL]), upper jaw length (14.7–20.0% of SL) and predorsal length (43.4–46.0% of SL), and a slender pelvic disc with thin frenum (length: 21.7–26.2% of SL; base width: 4.2–6.3% of SL). These unique morphological characters of R. fotuno sp. nov. may be related to the limnetic habitat of the species.
