Compsaraia samueli differs unambiguously
from C. compsa by the presence of the following character states:more caudal-fin rays (17–18 [mode 18] vs. 13–16 [mode 14]); a shorter caudal peduncle (CP/LEA = 9% [0–23%] vs. 34% [18–46%]); a less tapering body shape in lateral profile, in which the ratio of body depth measurements at the anal fin and dorsal organ origins is greater (93% [80–116%] vs. 75% [67–82%]); and a smaller body size (minimum
size at sexual maturity 144 mm [vs. 165 mm], maximum total length of 230 mm [vs. 305 mm]). Compsaraia samueli may be further distinguished from C. compsa by secondary sexual dimorphisms in several features of snout and jaw morphology (Ref. 80384).
Body shape (shape guide): elongated; Cross section: compressed.

Electric organ discharge known from two sexually mature
females and three sexually mature males. The two female specimens exhibited a lower Fo (1.242–1.243 kHz) than the three male specimens (1.337, 1.387 and 1.396 kHz) (Ref. 80384).
