Rm. Mcdowall, 2 FURTHER NEW SPECIES OF GALAXIAS (TELEOSTEI, GALAXIIDAE) FROM THE TAIERI RIVER, SOUTHERN NEW-ZEALAND, Journal of the Royal Society of New Zealand, 27(2), 1997, pp. 199-217
Two new species of Galaxias have overlapping distributions in the lowe
r Taieri River catchment, Otago, although not as yet found in sympatry
. Galaxias pullus n.sp. is known from several tributaries of the Waipo
ri River up- and downstream of Lake Mahinerangi, and also from a tribu
tary of the Waitahuna, part of the Clutha River catchment. Galaxias el
doni n.sp. comes from several small tributaries of the lower Taieri ne
ar Outram and Middlemarch, from a tributary of the Waipori River below
Lake Mahinerangi, from a tributary of the lake, and also a west branc
h tributary of the Tokomairiro River. These new species belong within
the Galaxias vulgaris species-group, which otherwise includes the nomi
nate species, G. anomalus and G. depressiceps. Most populations of thi
s species-group south of the Waitaki River are not G. vulgaris (sensu
stricto), but belong to one of four other species now recognised from
the region. The known distributions probably reflect a combination of
incomplete knowledge and fragmentation of ranges resulting from the ef
fects of introduced species.
