Y. Keivany et al., VALIDITY OF PUNGITIUS-HELLENICUS STEPHANIDIS, 1971 (TELEOSTEI, GASTEROSTEIDAE), A STICKLEBACK FISH FROM GREECE, Copeia, (3), 1997, pp. 558-564
The validity of Pungitius hellenicus, a stickleback fish from Greece,
is confirmed in a morphological study of specimens from throughout the
range of the genus. Three characters distinguish P. hellenicus from b
oth P. pungitius and P. platygaster: reduced ectocoracoid, fewer dorsa
l spines (2-6 vs usually 7-12), and all dorsal spines vertically arran
ged (vs some being inclined). The absence of a caudal peduncle keel fu
rther differentiates P. hellenicus from P. pungitius, and the absence
of the large lateral scutes and a complete pelvic girdle differentiate
s P. hellenicus from P. platygaster.
