Farlowella wuyjugu can be diagnosed from
its congeners by lack of plates in gular region (vs.
gular plates present). The new species can be distinguished
from its congeners, except Farlowella altocorpus

on anterior region of body (vs. four). Additionally,
F. wuyjugu differs from F. altocorpus
and F. azpelicuatae by having a smaller body
width at dorsal origin (4.3–5.5 vs. 6.4–8.1%
SL); from F. gianetti by number of caudal-fin
rays (i,11,i or i,12,i vs. i,10,i); from F. gracilis
by having head triangular in dorsal view (vs. head
square); from F. guarani by interorbital
width (12.0–16.0 vs. 28.6–44% HL) and
eye diameter (3.6–5.8 vs. 6.6–13.3% HL);
from F. hasemani by all fin rays uniformly
pigmented (vs. fin rays not pigmented); from F.
isbruckeri and F. odontotumulus by having
the ventromedian row of anterior plates keeled (vs.
ventromedian row of anterior plates unkeeled); from
F. jauruensis by having five branched pelvic-fin
rays (vs. four branched pelvic-fin rays); from F.
myriodon by having dark brown lateral stripe
on each side of snout (vs. absence of such stripe,
snout completely dark); and from F. nattereri
by having a short pectoral fin, not reaching the pelvic-fin
base (vs. long pectoral fin, reaching the pelvic-fin
base), Dopazo M. et al. (2023).
