Galaxias gollumoides is a new species described from the Island Hill
wetlands in central Stewart Island (east of Mason Bay), and the Robertson River
in southern Stewart Island. It is the first endemic
Galaxias from the
island, although another non-diadromous species,
G. depressiceps, is
present there, as well as four diadromous species of
Galaxias. G.
gollumoides appears to belong to the
G. vulgaris species group,
which otherwise includes
G. vulgaris Stokell,
G. depressiceps
McDowall and Wallis,
G. anomalus Stokell,
G. eldoni
McDowall,
and
G. pullus McDowall, all of which are known
primarily from the eastern South Island of New Zealand.
G. gollumoides
differs from all of these particularly in usually having only 6 pelvic fin
rays, and from all except
G. anomalus in that the eye is usually more
than 23% of head length. Further fish from tributaries of the Freshwater River
in northern Stewart Island and the Rakeahua River in central Stewart Island are
identified as
G. depressiceps, which is widely distributed across Otago
and Southland.
Gobiomorphus breviceps (Stokell) (Eleotridae) is recorded
from Stewart Island for the first time.
