Figure 2. Reanalysis of Goloboff's (1993) data set of 71 morphological characters scored for 42 mygalomorph taxa using implied weights (k = 7; note that the topology is quite sensitive to concavity function constant). This is a strict consensus of 27 most parsimonious trees (236 steps, CI = 0.39, RI = 0.73). Filled circles indicate nodes that differ from Goloboff 's original analysis, cyrtaucheniid taxa are in grey shaded box. A summary and a brief explanation of the characters and their scorings are presented in Appendix 1.
