Abstract Genetic differentiation among populations
of the Tarndale bully and three other Gobiomorphus species was investigated
with mitochondrial DNA sequence variation. Sequences from parts of the mitochondrial
cytochrome b gene and control region were obtained for 70 bullies. Specimens
of Tarndale bully, known from only five small tarns in the northern South
Island of New Zealand, clustered with specimens of common bully from both
North Island and South Island locations, and not upland or Cran’s bullies.
The molecular results are discussed in relation to the morphometric and meristic
variation, and the origin of the Marlborough tarns. It is concluded that
populations of bullies in the Marlborough tarns are a lake-locked ecophenotype
of the common bully and not a phylogenetic species.
