Figure S1.Linyphiid phylogeny resulting from Maximum Likelihood analysis based on molecular data. Numbers at the nodes are bootstrap value. Branches in color indicate the four robustly supported clades within linyphiids: S Stemonyphantes clade (blue) L1 “linyphiines”-1 clade (pale green) L2 “linyphiines-2” clade (dark blue) ME “micronetines-erigonines” clade (red, with “Distal erigonines” clade in green). Taxa in different colors sampled from different groups: grey, outgroup; blue, Stemonyphantinae; pale green, Linyphiinae; dark blue, Mynogleninae; pink, Dubiaraneinae; black, Micronetinae; red, Ipainae, Acanthoneta and Acanoides gen. n.; green, Erigoninae. Red stars indicate the two out-group taxa: cyatholipid Alaranea and theridiosomatid Theridiosoma embedded within Linyphiidae.
