Figure 5 in On the evolution and diversification of an Andean clade of reptiles: combining morphology and DNA sequences of the palluma group (Liolaemidae: Phymaturus)
Figure 5. Evolution of head melanism, optimized on one of the eight most parsimonious trees found from totalevidence analysis for the palluma group (all topologies imply the same scheme of changes for this particular character); blue, melanic head pigmentation absent, reticulated pattern conspicuous or in some cases any pattern at all; green, melanic throats and sides of heads, dorsum of head reticulated; purple, complete melanic heads (throats, sides, and dorsum of heads).

Figure 9. A, temporal scales of Phymaturus dorsimaculatus (MCN 1569) showing two organ scales (character 233); scale bar, 2 mm. B, cloacal region of Phymaturus verdugo (MCN 1960; Character 236); scale bar, 5 mm. C, female of Phymaturus verdugo (MCN 1958; snout–vent length, SVL = 99.8 mm; character 237). D, Phymaturus querque male (MCN 3863; SVL = 104.9 mm; character 249). E, Phymaturus paihuanense female (SSUC–Re 0422; photo by A. Laspiur; character 252). F, hemipenis of Phymaturus roigorum (MCN 1963; character 253); scale bar, 5 mm.
Figure 8. A in On the evolution and diversification of an Andean clade of reptiles: combining morphology and DNA sequences of the palluma group (Liolaemidae: Phymaturus)
Figure 8. A, tibial dorsal scalation of Phymaturus patagonicus (MCN 3561). B, central area of the same view of P. patagonicus (same specimen) tibia, showing scales in detail (character 220). Almost every dorsal tibial scale carries a spine and a scale organ on the distal tip of the scale (arrow; character 222). C, tibial dorsal scalation of Phymaturus palluma (MCN 3131). D, central area of the same view of P. palluma (same specimen). Scale organs hidden under the scale spines. E, tibial dorsal scalation of Phymaturus denotatus (MCN 3160). F, central area of the same view of P. denotatus (same specimen). The arrow indicates granular scales spread out among tibial scales (character 223). Scale bars: A, C, E, 5 mm; B, D, F, 2 mm.
Figure 10. A in On the evolution and diversification of an Andean clade of reptiles: combining morphology and DNA sequences of the palluma group (Liolaemidae: Phymaturus)
Figure 10. A, orbitosphenoid bone in Phymaturus aguanegra (MCN 968; character 240); the arrow indicates the cartilaginous margin of the fenestra epioptica. B, Phymaturus zapalensis (MCN 1486). C, ectopterygoid of Phymaturus spurcus (MCN 1249; character 241). D, same bone in Phymaturus laurenti (MCN 326). Abbreviations: ecp, ectopteygoid; fep, fenestra epioptica; fm, fenestra metoptica; fop, fenestra optica; fpr, fenestra prootica; j, jugal; pt, pterygoid. Scale bars: 1 mm.
Figure 3 in On the evolution and diversification of an Andean clade of reptiles: combining morphology and DNA sequences of the palluma group (Liolaemidae: Phymaturus)
Figure 3. Independent topologies found by separate molecular and morphological analyses (the numbers below branches in A, B, and C, represent jackknife values). A, strict parsimony analysis of morphological data. B, implied weights analysis (k = 3) of morphological data. C, all-genes analysis with strict parsimony. D, Bayesian analysis of all genes concatenated. Numbers below branches represent posterior probabilities (>0.70). Green nodes are those congruent with the total-evidence analysis.
Figure 7 in On the evolution and diversification of an Andean clade of reptiles: combining morphology and DNA sequences of the palluma group (Liolaemidae: Phymaturus)
Figure 7. Epiaxial musculature fascia (characters 216–219): A, no pigmentation of fascia dorsal among axial muscles of Phymaturus roigorum (MCN 2102); B, lateral pigmentation between axial muscles forming longitudinal lines, neural spines delineated in black in Phymaturus aguanegra (MCN 3288). C, lateral and dorsal fascia of axial muscles pigmented in Phymaturus spurcus (FML 1244). D, same condition, but less melanic, observed in Phymaturus tenebrosus (MCN 1263). Neural spines highlighted in white. Scale bars: 10 mm. Abbreviations: ld, longissimus dorsi muscle; ts, transversospinalis muscle.
