|Distribution||New Zealand (North Island)|
Type locality: Te Papa, Blue Mountains, Hutt Valley, Wellington [neotype].
|Reproduction||viviparous. Litter size ranges between one and four.|
|Types||Neotype: NMNZ RE1816 (National Museum of New Zealand), S193, designated by Hardy (1977).|

Holotype: NMW 16651 [micans]
|Comment||Synonymy: see PATTERSON et al. 2013 for a more detailed synonymy. This species has been confused with O. aeneum and therefore the name ornatum (and variations have been used for aeneum as well. This species has also been confused with Oligosoma smithi (GRAY 1845). In fact, Hardy (1977) recognized that one of the syntypes of Mocoa smithii Gray 1845 was in fact typical of C. aenea (Chapple et al. 2008).|
Type Species: Cyclodina aenea GIRARD 1857 is the type species of the genus Cyclodina GIRARD 1857. Note that four names (Cyclodina, Oligosoma, Lygosomella, and Hombronia), all contained in the same publication (Girard, 1857), are simultaneously the oldest available for this single genus, although only Cyclodina and Oligosoma have been subsequently used for part of it. A diagnosis of Cyclodina can be found in HARDY 1977: 230.
McCann (1955) restricted the name C. aenea to populations south of the 38° latitude, which lies approximately 300 km south of the Bay of Islands, and placing populations north of the 38° latitude in the new species Sphenomorphus pseudornatus. Hardy (1977) subsequently synonymized S. pseudornatus under C. aenea and resurrected Cyclodina ornata from synonymy. Lygosomella and Hombronia have been previously treated as junior synonyms of Oligosoma (by Patterson and Daugherty, 1995).
Diagnosis.—Cyclodina aenea can be distinguished from most other Cyclodina by its small body size and low midbody scale count of 26–32 rows, compared with Cyclodina macgregori (37– 45; Hardy, 1977), Cyclodina alani (36–44; Hardy, 1977), Cyclodina whitakeri (34–38; Hardy, 1977), C. townsi (38–44; Chapple et al., 2008) and C. oliveri (34–42; Chapple et al., in press). It can be distinguished from C. ornata by body size and color pattern, in particular the lack of a ‘‘teardrop’’ under the eye. Unlike C. hardyi, it has a continuous row of subocular scales (Fig. 3 in CHAPPLE et al. 2008). It can be separated from C. levidensa by a combination of higher scale counts and more heavily built body and limbs (Fig. 2D in CHAPPLE et al. 2008).
|Etymology||Named after its color: Latin “aenea/-us” = bronze, copper, or ore.|
