|Distribution||Forested areas of S Tanzania, south through Mozambique, Malawi and E Zimbabwe to N Zululand (Republic of South Africa)|
Type locality: Inyangani Tea Estates, Inynaga District, Zimbabwe.
|Types||Holotype: NMZB, previously UM 8354|
|Diagnosis||Diagnosis. An eastern race of Natriciteres variegata distinguished from the typical form by having 17 dorsal scale rows anteriorly, from bipostocularis by normally having three postoculars and from pembana by its higher ventral and subcaudal counts (from BROADLEY 1966).|
Coloration. Dark olive brown above, with a faint indication of a pale nuchal
collar, upper labials yellow with black sutures; ventrum yellow with outer ends of ventrals and subcaudals dark grey. The wide range of coloration found in N. olivacea is also found in N. v. sylvatica, some specimens have a maroon dorsal stripe, others are chestnut with a darker dorsal stripe. Specimens from Rungwe Mountain, Tukuyu and Nkata Bay have head markings similar to those of typical N. variegata: the top of the head is heavily stippled with black, apart from pale patches on the forepart of the parietals, and there is a well-defined cream collar which is narrowly broken on the vertebral line (from BROADLEY 1966).
|Comment||Habitat: at least partially coastal and thus considered (partially) “marine”.|
