Metriura Drolshagen & Bäckstam, 2009 (Araneae: Dipluridae) is a junior synonym of Fufius Simon, 1888 (Araneae: Cyrtaucheniidae)

ABSTRACT

The monotypic diplurid Metriura Drolshagen & Bäckstam, 2009 is placed in synonymy with Fufius (Cyrtaucheniidae) syn. nov. since Metriura lacks two of three diplurid synapomorphies (elongate posterior lateral spinnerets and the widely separated posterior median spinnerets) and shares synapomorphies with both aporoptychine cyrtaucheniids (subquadrate maxilla and a longer than wider labium) and Fufius (recurved and broad fovea, the typical incrassate tibia I of the male, with the spur having a single short branch and an apical megaspine, the basally curved metatarsus I and provided with a ventral tubercle). The type species of Metriura, M. striatipes Drolshagen & Bäckstam, 2009 is considered valid, and due to the synonymy of Metriura with Fufius, Fufius striatipes (Drolshagen & Bäckstam, 2009) comb. nov. is established.
