Bostrychus microphthalmus
Bostrychus microphthalmus is a species of fish from the family Butidae. It is endemic to Maros karst in southern Sulawesi, Indonesia. It was the first documented cave-dwelling fish in Sulawesi, but since then the brotula Diancistrus typhlops has been described from nearby Muna Island, and an additional apparently undescribed eleotrid is known from Sulawesi's Maros karst.
The specific name of B. microphthalmus refers to the small eyes of this fish.
