Orocrambus sophronellus

Orocrambus sophronellus is a moth in the family Crambidae. This species is endemic to New Zealand. This species has been classified as Data Deficient by the Department of Conservation.

Taxonomy
This species was first described by Edward Meyrick in 1885, from a specimen given to him by Richard William Fereday. Meyrick named the species Crambus sophronellus. Meyrick gave a more detailed description of the species later that year. In 1928 George Vernon Hudson also described and illustrated the species. In 1975 David E. Gaskin placed the species in the genus Orocrambus. Gaskin argues that Hudsons illustration in his 1928 book is actually of the species O. cyclopicus. The type locality of the specimen is uncertain but is possibly Canterbury. The type specimen is held at the Natural History Museum, London.

Meyrick described the species as follows: "Female. — 19 mm. Head and thorax ochreous-white, coarsely irrorated with greyish-fuscous. Palpi long, whitish, externally irrorated with grey.
