|Diagnosis||Diagnosis. O. newmani can be distinguished from other species in the O. infrapunctatum species-complex by a combination of characters (Figure 4a–j). There are statistical differences between O. newmani and O. salmo sp. nov. (S-Ear/EF, VS, upper ciliaries). Compared with O. salmo sp. nov. MS is usually 33 or below whereas O. salmo is mostly 33 or above. There are statistical differences from O. robinsoni (AG/SF). Compared with O. robinsoni subdigital lamellae are usually 20 or below whereas usually 20 or above in O. robinsoni. O. newmani has a shorter tail relative to SVL than O. robinsoni. Compared with O. albornense sp. nov. nuchal pairs are usually 3 or below versus 3 or above (O. albornense); usually 69 or more VS (O. newmani) versus 69 or fewer VS (O. albornense sp. nov.). HL/HW is always 1.7 or below in O. albornense sp. nov. whereas it is usually 1.7 or above in O. newmani. O. auroraensis sp. nov. usually has more than 20 subdigital lamellae on fourth hind toe versus 20 or fewer for O. newmani. The mean TL/SVL in O. auroraensis sp. nov. is 1.38 compared with 1.22. There is also a significantly higher VS count in O. auroraensis sp. nov. compared with O. newmani [Melzer et al. 2019: 462].|
|Comment||Synonymy: mostly after Melzer et al. 2019, who revalidated O. newmani but whose synonymy is also somewhat confusing as it remains unclear if all the listed authors really dealt with O. newmani.|
Habitat: wide range of warm-to-cool and low-to-very high rainfall environments from the coast to mountains (up to 1400 m ASL), occupying various habitats from coastal scrub/forest on islands, cobble and boulder beaches, dune vegetation and pakihi wetlands on coastal flats, densely vegetated or shrubland habitats, open grasslands, fernland, and cool tempe- rature tussock-scrub-low forest mosaic forest on the rocky plateaux in alpine regions; includes glacial river terraces in cool inland beech country. Terrestrial.
Behavior: Diurnal, strongly heliothermic.
Variation: This species can be highly variable in size and colour.
|Etymology||Named for Donald G. Newman of New Zealand, in recognition of his contributions to herpetology (Wells & Wellington 1985).|
