Bostrychus microphthalmus

Bostrychus microphthalmus is a species of fish from the family Butidae.[1][2][3] It is endemic to Maros karst in the South Sulawesi region of Sulawesi, Indonesia. It was the first documented cave-dwelling fish in Sulawesi,[1] but since then the brotula Diancistrus typhlops has been described from nearby Muna Island,[4][5] and an additional apparently undescribed eleotrid is known from Sulawesi's Maros karst.[6]
