A new species of warty catfish has been described from Sumatra in a recent issue of the journal Zootaxa.
The species, named Parakysis hystriculus by Heok Hee Ng, is known from southern Sumatra and is named after its long accessory mandibular barbels, which give it a hairy or bearded (Latin: hystriculus) appearance.
Parakysis hystriculus is distinguished from other Parakysis species in a combination of head, lower-lip, pelvic-fin, anal-fin and caudal-fin shapes, number and length of the accessory mandibular barbels, mandibular laterosensory pore between the bases of the inner and outer mandibular barbels present, and caudal fin with 10 branched rays without secondary branches.
This species inhabits brown water habitats associated with peat swamps.
