Taxonomy

O. ornatus was first described by Alfred Philpott in 1927[2] using a male specimen he collected in Golden Downs on 8 January 1926.[3][4] Philpott named the species Crambus ornatus.[2] George Vernon Hudson described and illustrated the species under the same name in 1939.[5] In 1975 David Edward Gaskin assigned Crambus ornatus to the genus Orocrambus.[4]

Description

Philpott described the species as follows:

20 mm. Head and palpi ochreous. Antennae brown. Thorax brown mixed with white. Abdomen whitish-ochreous. Legs white, anterior pair fuscous. Forewings, costa moderately arched, apex blunt-pointed, termen rounded, oblique; brassy brown to chocolate brown; markings white; a basal patch on costa half enclosing a brown area; a broad irregular band at ​1⁄4, not reaching dorsum, outwardly strongly dentate; on fold before this a large spot of mingled blackish and white scales; an elongate black mark about middle of wing at ​1⁄3; a crescentic white area sprinkled with brown on costal half from about ​1⁄3 to ​4⁄5, enclosing an elongate spot of blackish-brown on costal margin; beneath this costal spot a prominent ring of brown enclosing a white area with a central brown dot; second line pure white, dentate, preceded on costa by a small blackish-brown dot and followed by a much larger one; a white area beneath the latter reaching apex; fringes fuscous, irregularly barred with white. Hindwings and fringes pale ochreous-grey.[2]

Distribution

This species is endemic to New Zealand[6][7] and has been recorded in Golden Downs in the Tasman District[4] as well as in the Nelson district.[8]

Ecology and habitat

Host plants

This species has been found to be associated with plants in the genus Uncinia.[8]

Conservation Status

This species has the "Nationally Critical" conservation status under the New Zealand Threat Classification System.[1]
