Collins ; Event: eventDate: 2013-11 ; Record Level: institutionCode: INPA ; basisOfRecord: PreservedSpecimen Notes Identification to species level follows Sousa (2010) based on the following characters: flattened body shape; upper limit of pre-opercular canal not reaching lateral border of the cranium; seven branched rays in the dorsal lobe of the caudal fin; dorsal margin of the orbit high; procurrent rays of the caudal fin expanded into bony shields; and diverticula of the swim bladder simple, with tapered rear end. Two individuals were caught by hand-net at night over a sandy/silty substrate (sampling site NH12). An example of a live specimen is pictured in Fig. 9.
