Figure 5. Preferred single tree resulting from the analysis under implied weights with concavity constant k in Systematics of the genus Mayazomus (Arachnida: Schizomida): the relevance of using continuous characters and pedipalp setae patterns to schizomid phylogenetics

Figure 5. Preferred single tree resulting from the analysis under implied weights with concavity constant k = 100. Clade support is indicated above (Bremer support values) and below [symmetric resampling values; only significant values (over 50%) are presented] branches. Sensitivity plots ('Navajo rugs') indicate the recovery of the nodes in the analysis under implied weights with different values of k (black squares indicate monophyly; white squares indicate nonmonophyly).

Figure 7 in Systematics of the genus Mayazomus (Arachnida: Schizomida): the relevance of using continuous characters and pedipalp setae patterns to schizomid phylogenetics

Figure 7. Strict consensus tree of five most parsimonious trees obtained by excluding continuous characters from the analysis with equal weights. The tree shows the poor resolution of the relationships inside Mayazomus and the inclusion of Hansenochrus as the sister group of Rowlandius, demonstrating the importance of continuous characters for phylogenetic studies in Mayazomus.

Figure 6. Preferred single tree resulting from analyses under implied weights with concavity constant k in Systematics of the genus Mayazomus (Arachnida: Schizomida): the relevance of using continuous characters and pedipalp setae patterns to schizomid phylogenetics

Figure 6. Preferred single tree resulting from analyses under implied weights with concavity constant k = 100, 60, and 30, and equivalent to one of the most parsimonious trees recovered in the analysis with equal weights and continuous characters. Images on the tree represent the morphological congruence of the clades with the structures pictured (pedipalps and spermathecae). The genus Mayazomus is clearly separated from Rowlandius by the presence of robust pedipalps and trochanters with apical process; the clade (Mayazomus yaax + Mayazomus estor) is supported by the rounded distal margin of the pedipalp femur; the clade (Mayazomus loobil + Mayazomus infernalis) is supported by the presence of a patella curved in a 'U'-shape; and spermathecae with lobes slender and subequal in length; the clade (Mayazomus aluxe + Mayazomus kaamuul) is supported by setae Fv1 and Fv2 located distally and projected, with spermathecal lateral lobes reduced and wider than medial lobes.
