 note = {A taxonomic revision of the polynemid fish genus Eleutheronema, which is redefined, resulted
in three species of the genus being regarded as valid: Eleutheronema rhadinum (Jordan and Evermann,
1902), having to date been treated as a junior synonym of E. tetradactylum (Shaw, 1804) and currently
known only from East Asia (China and Japan) where it is endemic; E. tetradactylum, a senior synonym
of both Polynemus teria Hamilton, 1822 and Polynemus coecus Macleay, 1878, being a widely distributed
Indo-West Pacific species, which ranges from the Persian Gulf to Australia; and E. tridactylum
(Bleeker, 1845), distributed in Southeast Asia (Thailand, Malaysia, and Indonesia). Eleutheronema
tridactylum is easily distinguished from both E. rhadinum and E. tetradactylum owing to the vomer
lacking tooth plates in the former [vs. vomer with 2 deciduous tooth plates (in specimens at least
over ca. 70 mm SL) in the latter] and lower counts of pectoral filaments (free lower rays, 3 vs. 4) and
gill rakers [mode 8 (range 4–10) vs. 12 (10–17) and 13 (6–18) in E. rhadinum and E. tetradactylum,
respectively]. Eleutheronema rhadinum clearly differs from E. tetradactylum in having higher counts of
pored lateral line scales [mode 95 (range 82–95) vs. 73 (71–80) in the latter] and higher scale counts
above and below the lateral line [12 (11–14) and 16 (15–17), respectively, vs. 10 (9–12) and 14 (13–15),
respectively]. Furthermore, E. rhadinum is distinguished from E. tetradactylum by having a dense black
pectoral fin [vs. vivid yellow in life (except in specimens over ca. 350mm SL, pectoral fin dusky-yellow)
in the latter]. Intraspecific variations and morphological changes with growth of the three species are
also discussed.},
