It differs from all other species of Dysalotus in having a greater number of teeth on the premaxilla (151-198 v. 60-138) and dentary (136-199 v. 76-132) and in a shorter upper jaw [51·9-54·9% of head length (LH) v. 62·4-74·4% LH] and lower jaw (64·8-67·4% in LHv. 75·3-88·1% in LH). A key for the species of Dysalotus and an updated distribution map are provided. http://zoobank.org/urn:lsid:zoobank.org:pub:E9B5F1DC-52E0-4F53-9109-2A8E252AE8CE.
