[Entomology • 2019] Ypsolopha rhinolophi • A New Species (Lepidoptera: Ypsolophidae) from Portugal and France unveiled by Bats

 Ypsolopha rhinolophi Corley

in Corley, Ferreira & Mata, 2019. 

A new species Ypsolopha rhinolophi Corley is described from northern Portugal and south-east France. It resembles Y. alpella (Denis & Schiffermüller, 1775) and Y. lucella (Fabricius, 1775) but shows clear differences from both species in DNA barcode and in male and female genitalia. Male genitalia of Y. lucella are illustrated for the first time. The new species has been collected at light, reared from larvae on Quercus pyrenaica Willd. and recognised from DNA barcode fragments obtained from droppings of horseshoe bats.

Diagnosis. Y. rhinolophi is immediately separable from Y. alpella by the black-ringed white antenna, and differs from the most closely related species Y. lucella (Fig. 1E) in the absence of white scales on head and thorax. Further differences externally and in genitalia from both of these species are presented in Table 2 and Figs 1–3. Both Y. lucella and Y. alpella have larvae feeding on Quercus. There are other European Ypsolopha species feeding on Quercus: Y. sylvella (Linnaeus, 1767) is a close relative of Y. alpella, but is easily distinguished from the new species by two dark lines obliquely crossing most of the forewing. Y. parenthesella (Linnaeus, 1761) and Y. ustella (Clerck, 1759) also feed on Quercus, but are not similar in appearance to Y. rhinolophi.

Distribution. In Portugal Ypsolopha rhinolophi is known from direct collection of larvae or adults from two localities in Trás-os-Montes in the north-east Portugal and from single localities in Beira Alta and Beira Litoral, and from a photographed moth in Minho in the north-west of the country which clearly shows the coloration, wing shape and black and white antennae of the new species (Fig. 1C). In addition, DNA metabarcode samples obtained from bat droppings indicate its presence in two additional localities in Trás-os-Montes (see Fig. 4).
 In France it is known from a single locality in Basses Alpes in the south-east of the country. Suitable habitat exists for Y. rhinolophi in Spain, so the species is likely to occur in the country. 

Etymology. The species name rhinolophi recognises the part played in the discovery of the new species by the horseshoe bats Rhinolophus ferrumequinum and Rhinolophus euryale. The name is a noun in genitive case
