Description: Bumblebee Jelly Catfish has a dark brown to black overall body color with a white to cream color collar behind the gill cover. A whitish marking is also present on the body just below the dorsal fin, and there is a light colored band (which may be incomplete) before the caudal peduncle and a pair of white markings on the caudal peduncle. There is also a creamy marking at the base of the adipose fin. The head is depressed with small eyes. Young fish can be confused with members of Microglanis, but Microglanis typically have much more extended light areas and the overall body is not as robust.
Most of the specimens in the aquarium hobby are exported from the Brazilian Amazon and are rarely grow beyond 12 cm. Because of their wide distribution and the great amount of size and coloration differences reported it is likely that this is either a very variable species or a collection of closely related species with similar color patterns.
External sexual differences are unknown, but females are probably more robust especially at the ventral area. Bumblebee Jelly Catfish breeding habits are also unknown.
