Abstract
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.
