Oligosoma repens — HITCHMOUGH et al. 2016
Type locality: Mt Nicholas Road, Eyre Mountains, (45° 15’S, 168° 18’E), New Zealand.
|Types||Holotype: NMNZ RE007279, adult male (coll. T. Bell, 2009).|
|Diagnosis||Diagnosis. Oligosoma repens can be distinguished from other related Oligosoma species through a combination of characters (Figure 4 in CHAPPLE et al. 2011). Compared to O. maccanni, O. repens has a glossy appearance, with brown predomi- nating whereas O. maccanni has a greyer ground colour. Oligosoma maccanni has a pale grey ventral colour rather than the bright yellow ventral colour in O. repens. 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. repens. Oligosoma maccanni has four supraocular scales compared with three in O. repens. Oligosoma polychroma from nearby areas have very similar colour patterns to O. repens, but can be distinguished by a pale dorsal stripe on the outside of the forelimbs, and a greyish-brown ventral colouration. The ear opening in O. polychroma often has prominent projecting scales on the interior margin. There are statistical differences between O. repens and O. toka (SVL/HL, SVL/HLL, ventral scales), O. burganae (AG/SF, SE/EF, HL/HW, SVL/HL), and O. notosaurus (SVL/HL, ventral scales) (Figure 4). All O. repens have three supraoculars whereas all O. inconspicuum and O. notosaurus have four. The number of subdigital lamellae in O. tekakahu (16) is fewer than O. repens (19–23). The dorsal surface of the head is usually unmarked in O. repens, in contrast with O. toka and O. notosaurus in particular. The species is more gracile than the other members of the species complex [from CHAPPLE et al. 2011].|
|Etymology||From ‘repens’ (Latin, neuter) = unexpected. Refers to the unexpected discovery of a genetically divergent new species in the Eyre Mountains that occurs sympatrically with O. inconspicuum (sensu stricto).|
