Collins ; Event: eventDate: 2013-11 ; Record Level: institutionCode: INPA ; basisOfRecord: PreservedSpecimen Notes Identification to species level follows Eigenmann and Norris (1900) and Eigenmann (1912) based on the following characters: rounded caudal fin with larger lower lobe; distinct cranial fontanelle; maxillary barbels long, extending to caudal (extended only to caudal peduncle in our specimen); dorsal spine notched anteriorly; dark stripe along lateral line (in our specimen this comprised just a elongated blotch under the dorsal fin); base of caudal with dark bar; and obliquely angled dark saddle behind head (from dorsal insertion to base of opercle); and body and fins irregularly mottled. One individual was caught by hand-net on the Rio Paratucu (sampling site NH10), and delivered a painful sting, confirming that many heptapterids are venomous ( Wright 2009 ). This specimen is pictured in Fig. 11.
