Pyroderces aellotricha

This species was first described by Edward Meyrick in 1889 and named Proterocosma aellotricha.[2] Meyrick, when first describing the species, used two specimens collected in Hamilton in January.[2] In 1915 Meyrick placed this species within the genus Pyroderces.[3] The female lectotype, collected in Hamilton, is held at the Natural History Museum, London.[4]

Meyrick described the species as follows:
