Etymology: Hypopygus: Greek, hypo = under + Greek, pyge = tail (Ref. 45335); hoedemani: The specific epithet, hoedemani, is a patronym in honour of J. J. Hoedeman for his contributions to Neotropical ichthyology, including the description of H. lepturus, the type species of the genus (Ref. 88778).

Краткое описание
определительные ключи | морфология | морфометрия
Hypopygus hoedemani is diagnosed from congeners by the following combination of characters: the absence of the sixth infraorbital bone (versus presence in all congeners except H. lepturus and H. minissimus), the total number of anal-fin rays (102–118 versus 136–174 in all congeners, except for H. lepturus and H. minissimus), the length of the caudal filament (31.1–48.1% of LEA versus 48.4–80.9 in H. lepturus), the presence of oblique bands (versus absence in H. minissimus), the presence of scales at midbody (versus absence in H. minissimus), and the dorsal rami of intermittent branch of anterior lateral line nerve visible as two black parallel lines (versus not visible in H. ortegai) (Ref. 88778).
