Hahniidae

The inclusion of Cicurina in this family is discussed above under Dictynidae . The inclusion of Mastigusa is particularly weakly supported. The British species has formerly been placed in Tetrilus , Tuberta , and Cryphoeca . Its placement in Hahniidae is based on its presumed relationship to Cicurina (e.g., Murphy & Roberts 2015); Wunderlich (2004a) places it in Cryphoecinae instead. The two forms of British Mastigusa are here conservatively considered semispecies, rather than morphs of a single species, given their apparent ecological separation. However, if this interpretation is correct, the name of the macrophthalmus form would probably need to be changed, as the British specimens don’t seem to belong to the species originally described under this name from Eastern Europe ( Wunderlich 1995b). The relationships between the genera are based on analysis of the barcode data available for the family, as is the internal topology of Hahnia . The internal topology of Iberina is based on morphological affinities, but as the male of I. microphthalma is unknown, this remains tentative.
