Researchers from the University of Eastern Finland and the Zoological Museum of the University of Turku have published in the journal ZooKeys an official description for Scenopinus jerei, a new fly species from Finland. This 4-5 mm sized, slender blackish fly belongs to the fairly primitive and species-poor family of window flies (Scenopinidae). The best-known representative of the family is the cosmopolitan window fly (Scenopinus fenestralis), commonly found indoors in man-made dwellings. Besides the common window fly, another species, Scenopinus niger, was also previously known from Finland.
