FIGURE 5. Phylogenetic position of Kuroyuriella mikikoi gen. et sp. nov. and Asagaolacerta tricuspidens gen. et sp. nov. in squamate trees, using the morphological data matrix of Gauthier et al. (2012), extended by Longrich et al. (2012). 1, Strict consensus of 1000 trees using unordered equally weighted characters, and run using TNT with 'minisearch.run'. Major clades are condensed. 1Note that Iguania was not monophyletic and comprised four smaller clades whose position was unresolved in relation to Borioteiioidea. Support values at nodes are Bremer/Jacknife/Symmetric resampling; 2, one of three trees (identical at this level) with clades condensed, run using the same matrix as in Figure 5.1 and analysed with TNT (with sectorial search, ratchet [20 iterations], and tree fusion all activated), but with the molecular tree of Wiens et al. (2010) and Pyron et al. (2013) providing the backbone constraint.

FIGURE 6. The phylogenetic position of Kuroyuriella mikikoi gen. et sp. nov. as recovered by analyses run with Implied Weighting (k=7), and character ordering. 1, no backbone constraint; 2, backbone constraint tree based on the molecular trees of Wiens et al. (2010) and Pyron et al. (2013). Only the scincoid section of each tree is shown as in all analyses with equally weighted taxa, Kuroyuriella lies in the stem-squamate position shown in Figure 5.

FIGURE 12. The phylogenetic position of Asagaolacerta tricuspidens gen. et sp. nov. tested using different analytical protocols within TNT. 1, detail of Strict Consensus of 1000 trees using the protocol that yielded the tree in Figure 5.1, node support values Bremer/Jacknife/Symmetric sampling; 2, one of three trees resulting from an analysis using with the molecular backbone constraint tree, but no character ordering or weighting; 3, one of 58 trees from an analysis run as in (2), but with character ordering as per Gauthier et al. (2012) and Longrich et al. (2012), and Implied Weighting (k=7); 4, one of 34 trees from an analysis run as in (3), but without the molecular backbone constraint; 5, 70% MRT of 19 trees resulting from an analysis (characters ordered but equally weighted, no constraints) run using only the boreoteiioid taxa, with Gekko gecko as the outgroup taxon. The 70%MRT is presented rather than the unresolved Strict Consensus to show that Asagaolacerta tricuspidens is usually (88% of trees) placed in the basal position (see text for further discussion). Abbreviation: poly, polyglyphanodont (as used in Longrich et al., 2012).
