Family Linyphiidae Blackwall, 1859

Linyphiidae Blackwall, 1859: 261 .

Diagnosis: Araneoids with ectal cheliceral stridulatory striae and patella-tibia autospasy, both characters also present in Pimoidae , but distinguished from the latter family by the presence in the male palp of an intersegmental paracymbium (partially intersegmental or integral in some stemonyphantines), a suprategulum, a distal suprategular apophysis and an embolic division that connects to the suprategulum by means of a membranous stalk (the column) (e.g., see figures in Blauvelt (1936), Merrett (1963), Millidge (1977) and Hormiga (1994b, 2000)). A membranous outgrowth of the column (the embolic membrane) is present in most linyphiids but absent in stemonyphantines. Unlike pimoids, the base of the embolus is differentiated in most linyphiids into a sclerite (radix).

Phylogenetics: Linyphiid synapomorphies include the intersegmental paracymbium, suprategulum, a distal suprategular apophysis, column and radix.

Distribution: Worldwide.

Composition: 625 genera, including Weintrauboa and Putaoa (transferred to Linyphiidae in the present work).
