|Distribution||New Zealand (Otago, Southland)|
Type locality: Tree Island, Lake Wakatipu, 44° 55’ S, 168° 25’ E.
|Types||Holotype: NMNZ R2079, RE002079 fide CHAPPLE et al 2011|
|Diagnosis||Diagnosis. Oligosoma inconspicuum can be distinguished from other related Oligosoma species through a combination of characters (Figure 4; Wessa 2011). Compared to O. maccanni, O. inconspicuum 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 or bronze ventral colour seen in O. inconspicuum. 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. inconspicuum. Longitudinal striping is more pronounced in sympatric populations of O. poly- chroma, which almost always have a pale 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. inconspic- uum and O. burganae sp. nov. (AG/SF, HL/HW, SE/EF, SVL/HL, SVL/FLL), O. notosaurus (SVL/HL, ventral scales), and O. toka sp. nov (SVL/FLL, SVL/HLL ventral scales) (see Figure 4). Unlike O. repens sp. nov. and O. toka sp. nov. which have three supraoculars all O. inconspicuum have four supraoculars. Most O. burganae sp. nov. have only three supraoculars. Oligosoma repens sp. nov. has a more elongate appearance than O. inconspic- uum (e.g. TL/SVL of 1.28 and 1.16, respectively). The number of subdigital lamellae (17–23) is greater in O. inconspicuum compared to O. tekakahu sp. nov. (16) [from CHAPPLE et al. 2011].|
|Etymology||Named after inconspicuum, Latin for “not readily visible”, referring both to the difficulty in morphologically distinguishing this species from most of the other taxa in the L. nigriplantare species group, and the cryptic behaviour of this species in its natural environment.|
