Figure 2 in A completely resolved phylogenetic tree of British spiders (Arachnida: Araneae)
Figure 2. Selected morphological character states mapped onto the phylogenetic tree of British linyphiid spiders. The framework provided by the phylogenetic information allows the clear identification of patterns of character evolution, including a considerable degree of homoplasy for all characters. The definition of characters and character states is based on the linyphiid identification key by Anna Stäubli, provided on the Spiders of Europe website. The order of columns (from left to right) follows the order of the legends (from top to bottom). The left block of columns refers to characters applying to the male, the right to characters of the female. The female of Centromerus minutissimus has not yet been described.
