Type locality: Burgan Stream, Rock and Pillar Range (45° 35’S, 169° 56’E), New Zealand.
|Types||Holotype: NMNZ RE002390/1, adult female (coll. G. Patterson, 1982).|
|Diagnosis||Diagnosis. Oligosoma burganae can be distinguished from other related Oligosoma species through a combi- nation of characters (Figure 4 in CHAPPLE et al. 2011). Compared to O. maccanni, O. burganae has a glossy appearance, with brown predominating whereas O. maccanni has a greyer ground colour. Oligosoma maccanni has a pale grey ventral colour rather than the yellow/grey ventral colour seen in O. burganae. The ear opening in O. maccanni often has large projecting scales on the interior margin, whereas these are often minimal or lacking altogether in O. burganae. Longitudinal striping is more pronounced in sympatric populations of O. polychroma, which almost always have a pale dorsal stripe on the outside of the forelimbs. The ear opening in O. polychroma often has prominent projecting scales on the interior margin. There are statistical differences between O. burganae and O. inconspicuum (AG/SF, HL/HW, SE/EF, SVL/HL, SVL/FLL), O. toka sp. nov. (SVL/HLL, ventral scales), O. notosaurus (ventral scales), and O. repens sp. nov. (SVL/HL, SVL/FL, AG/SF) (Figure 4). All O. inconspicuum have four supraoculars whereas most O. burganae have only three supraoculars. Oligosoma repens sp. nov. has a more elongate appearance than O. burganae (TL/SVL of 1.1 and 1.28, respectively). The number of subdigital lamellae (18–23) is greater than in O. tekakahu (16). The head of O. burganae is noticeably blunter and deeper than O. repens sp. nov. and O. toka sp. nov. (Figures 4, 7–9) [from CHAPPLE et al. 2011].|
