Stuke, Jens-Hermann
Hyadina borkumensis sp. n. is described from the East Frisian Island of Borkum (Germany, Lower Saxony, Wadden Sea) based on a single female specimen. The new species is characterized by the basally bent, brown wings with large white spots in radial cells r₂₊₃, r₄₊₅ and apical of crossvein dm-cu and its short radial vein R₂₊₃. The new species shares the lateroclinate fronto-orbital seta with representatives of the Australasian–Oceanian genus Parahyadina Tonnoir & Malloch, 1926. The implication of this shared character for the use of relevant Ephydridae keys is briefly discussed.
