Diagnosis

Distinguished from other congeners by having the following combination of characters: nearly even brown body pigmentation; presence of an unpigmented, median, longitudinal stripe on the chin and snout; mid-dorsal electroreceptive filament extending to, or one scale beyond, the vertical through the base of the last anal-fin ray; tail depth 7.7-15.2% of CL; caudal length 16.2-24.4% of LEA; pectoral fin hyaline at the base and dark distally; anal fin hyaline at the base and

dark distally; 162-171 anal-fin rays; head length 12.1-18.2% of LEA; head depth 10.9-15.8% of LEA; pectoral-fin length 10.6-13.3% of LEA; prepectoral- fin distance 11.6-16.4% of LEA; greatest body depth 15.3-19.3% of LEA (Ref. 91753).
