Εδρικές άκανθες: 0. Diagnosis: adipose fin always present; anterior nostrils closer to each other or at same distance as posterior ones; barbels well developed, nasal barbel at least reaching to anterior border of opercle; snout reaching beyond lower jaw, upper lips slightly surrounding lower jaw when mouth is closed; inner side of pectoral spine feebly serrated; striking brownish colour pattern, often irregularly marbled and characterized by the presence of a very dark blotch above pectoral spine, where swim-bladder lies close below skin; eyes rather small (Ref. 43912).
Prefer smaller forest streams with rocky (Ref. 7248, 43912) or sandy bottom (Ref. 43912). Nocturnal (Ref. 43912). Probably carnivorous (Ref. 43912), with a preference for terrestrial and aquatic insects (Ref. 7248, 43912). Oviparous, eggs are unguarded (Ref. 205).
