Psechridae (Three-clawed spider)

Wikipedia Abstract

The Psechridae are a family of spiders with about 50 species in two extant genera, recently revised by Bayer (2011, 2012). They belong to the RTA clade of spiders, spiders that all have a Retrolateral Tibial Apophysis on the male pedipalp. A recent phylogenetic analysis places Psechridae as close relatives of the Lynx spiders (Oxyopidae), as well as wolf spiders (Lycosidae) and nursery web spiders (Pisauridae) (Agnarsson et al. 2013). With body lengths of up to 2 cm and funnel webs more than 1 m in diameter, they are among the biggest cribellate spiders. Psechrids construct cribellate webs and Fecenia construct webs that are similar to orb webs of Orbiculariae spiders, a remarkable example of evolutionary convergence (Blackledge et al. 2012, Agnarsson et al. 2013). Psechridae spiders are o
