FIGURE 3B. Phylogenetic tree of the genus Marisora from a maximum-likelihood analysis of DNA sequences of three mitochondrial genes (12S rRNA, 16S rRNA, and cyt b) and three nuclear genes (NGFB, R35, and RAG2) in 140 individuals (4,029 bp).

FIGURE 1. Head scalation in Neotropical skinks (Mabuyidae, Mabuyinae, Marisora). Locations and names of head scales on side (A) and top (B) of head. Abbreviations are AL (anterior loreal), F (frontal), FN (frontonasal), FP (frontoparietal), IP (interparietal), LST (lower secondary temporal), M (mental), NU (nuchal), P (parietal), PF (prefrontal), PL (posterior loreal), PT (primary temporal), R (rostral), UST (upper secondary temporal), and UTT (upper tertiary temporal). Chin scale configuration: (C) no contact between chin shields and infralabials; (D) two chin shields (each side) in contact with infralabials. In the former case, the sublabials contact the postmental whereas in the latter case they are separated by two chin shields. Nuchal scales: (E) one transverse row; (F) three transverse rows; note presence of enlarged dorsals (not scored as nuchals) in both cases. Adapted from Hedges & Conn (2012).
