|Abstract||When studying the Microlepidoptera fauna of Madeira, the second author came across two puzzling big specimens of the Olethreutinae (Tortricidae): one, a male from the Staatssammlung für Naturkunde, Karlsruhe, Germany, another, a female, from the Naturhistorisches Museum, Wien, Austria.|
The two specimens appeared to belong to one and the same, sexually dimorphous, apparently new species which is described below.
The holotype, ♂, will be deposited in the Karlsruhe Museum, the allotype, ♀, in the Vienna Museum.
We are indebted to the authorities of the Karlsruhe and Vienna Museums for the kindness of entrusting this material to us for identification.
The photographs of the genitalia have been made by Mr. Bent W. Rasmussen, Copenhagen Museum.
