Fig. 8 in New Species of Lizards from Auyantepui and La Escalera in the Venezuelan Guayana, with Notes on ''Microteiid'' Hemipenes (Squamata: Gymnophthalmidae)

Fig. 8. Anadia escalerae, new species. Lateral, dorsal, and ventral views of head of holotype (EBRG 1998). Unusual scales (gray tone in drawings) include fourth sublabial in contact with lip and azygous scale between paired prefrontals. Scalation of lower eyelid not shown in drawing because of desiccation and distortion; white areas in ventral view reflect insect damage. Scale lines 5 5 mm.

Fig. 4. Euspondylus auyanensis, new species. Trunk of holotype in lateral view (head to right), showing scalation at midbody, X4.6.

Fig. 7 in New Species of Lizards from Auyantepui and La Escalera in the Venezuelan Guayana, with Notes on ''Microteiid'' Hemipenes (Squamata: Gymnophthalmidae)

Fig. 7. Euspondylus auyanensis, new species. Apical view of the right everted (in situ) hemipenis of the holotype, showing complex folding of tissue. The two lobes are more closely appressed than in the left organ (fig. 6), probably because of maximal inflation pressure coupled with tension in the major retractor muscle. The following structures also are visible in figure 6 (left side): H, ''hood;'' R, rim of collar around ''basin'' (for impeding flow of seminal fluid?); SF, spinulate flounces; SS, sulcus spermaticus (distal branches not visible). Scale line 5 1 mm.

Fig. 6. Phylogenetic trees inferred from maximum parsimony analyses. (A) Strict consensus of 211 equally parsimonious trees estimated from morphology partition (L 5 106; CI 5 0.55; RI 5 0.72). (B) Single most parsimonious tree recovered from analyses of combined morphology and molecular partitions (L 5 2.740, CI 5 0.47, RI 5 0.43). The internal nodes are numbered (circles) and the partitioned Bremer support indexes are listed in appendix 4 for each node. Bootstrap support values (. 50%) and decay indexes are presented above and below branches, respectively. The inset includes Alexandresaurus camacan and its closest relatives.
