No sé si te será de alguna ayuda, pero esto es lo que viene en la descripción que hizo Costa en 2006, el resumen es que para los ojos de cualquier mortal son dos clones
:
"Differs from all other species of the A. bellottii group in having the anal-fin origin
situated between pleural ribs of 5th and 7th vertebrae in males, and between pleural ribs of
7th and 8th vertebrae in females (vs. between pleural ribs of 7th and 10th vertebrae in
males, between pleural ribs of vertebrae 9th and 11th in females). Differs from all
congeners, except A. bellottii, A. univentripinnis, and A. melanoorus, in having the entire urogenital papilla attached to the anal fin in males (vs. urogenital papilla free from the anal ZOOTAXA
fin); from A. univentripinnis in having more teeth on the second pharyngobranchial (8–12
vs. 6–8), more supraorbital neuromasts (20–24 vs. 17–18), more preopercular plus
mandibular neuromasts (43–47 vs. 39–41); from A. bellottii by possessing a longer analfin
base in males (50.8–54.8 % SL, vs. 44.9–50.8 % SL), larger eye in males (29.2–33.1 %
head length, vs. 25.4–28.6 % head length), usually having more vertical rows of bright
dots on the flank in males (11–18 vs. 7–12), and dorsal-fin origin between neural spines of
6th and 8th vertebrae in males, between neural spines of 9th and 11th vertebrae in females
(vs. between neural spines of 8th and 10th vertebrae in males, between neural spines of
11th and 12th vertebrae in females); from A. melanoorus by possessing distinct color
patterns: flanks dark bluish gray with vertical rows of bright greenish blue dots in males
(vs. light bluish gray bars alternating with dark gray bars), unpaired fins with bright dots in
males (vs. elongate light spots and bright lines parallel to fin rays), and females sometimes
with 1–3 black spots on center of the flank, often black spots absent (vs. always 5–16 black
spots)".
