Kupea is a monotypic moth genus of the family Crambidae described by Alfred Philpott in 1930.

The larvae feed on Zoysia minima and exist in a cocoon constructed of silk and sand.

Kupea electilis was first described by Alfred Philpott in 1930 using male specimens collected at Birdling's Flat, Kaitorete Spit by Stuart Lindsay in March.

[6] David E. Gaskin discussed the species in 1975 stating that once a female specimen was found the systemic position of the genus should be reassessed.

Forewings long, narrow, costa almost straight, apex blunt-pointed, termen rounded, strongly oblique; brassy ochreous sprinkled with white; a thick blackish brown median stripe from base to 2⁄3, interrupted by white markings as follows :—a linear spot beyond base on upper margin suffusedly white beneath, a rather broad outwardly oblique bar beyond this, a subovate spot on upper margin with a streak below it following along fold, a large circular spot at apex above; beyond apex of median stripe a large suffused roundish whitish patch; second line broad, curved, white, becoming obsolete on tornus, anteriorly brassy margined; dorsum suffusedly margined with white; fringes fuscous mixed with white on apical half and with a darker basal line.

[11] Kupea electilis is regarded as being "Nationally Vulnerable" under the New Zealand Threat Classification System.

[13] The main threats to this species include grazing cattle and introduced pests such as rabbits that eat its host plant,[11] weed invasion from plants such as sea spurge,[14] and the development or use of land by humans.
