FIGURE 11 in On the spider genus Weintrauboa (Araneae, Pimoidae), with a description of a new species from China and comments on its phylogenetic relationships
FIGURE 11. One of the four minimal length trees of 212 steps that result from the parsimony analysis of the data matrix presented in Appendix 1 (CI = 0.50, RI = 0.75). Exclusion of the six parsimony uninformative characters decreases the tree length to 203 steps and the ensemble consistency index to.48 Ambiguous character changes are resolved under "Farris optimization." Closed circles represent non-homoplasious character changes. The two nodes that collapse in the strict consensus cladogram of the four most parsimonious trees are marked with a closed rectangle. Numbers at nodes indicate Bremer support / parsimony jackknife frequency (only those above 50% are reported). The basal trichotomy has been resolved according to the araneoid topology presented in Griswold et al. (1998); see text for additional details of the cladistic analysis.
