FIGURE 1 in New Zealand forest-dwelling skinks of the Oligosoma oliveri (McCann) species-complex (Reptilia: Scincidae): reinstatement of O. pachysomaticum (Robb) and an assessment of historical distribution ranges

FIGURE 1. Map of upper North Island of New Zealand showing distribution records for extant populations of the four members of the Oligosoma oliveri species-complex. Bold outline = maximum expanse of land during the Otira Glaciation 18,000–20,000 years ago; thin outline = present extent of land; dotted line = former path of Waikato River; blue shading = suggested former distributional extent of O. townsi in this region; pink shading = suggested former distributional extent of O. pachysomaticum in this region.
