FIGURE 1 in Description of a new pygmy chameleon (Chamaeleonidae: Brookesia) from central Madagascar
FIGURE 1. Brookesia brunoi sp. nov., male [holotype (ZSM 888/2010)], in life, in lateral (A) and dorsal (B) views, and closeup view (C) of the lateral side of the head. Schematic drawings represent the two different kinds (three-tuberculated and fourtuberculated) of cephalic crest present in the B. decaryi group. i to iv: four pointed tubercles of the posterior portion of the crest; ILT: infralabial tubercle; IORr: interocular ridge; LRCr: lateral ridge of the crest; NCo: nasal cone; OCo: supraocular cone; PoCr: posterior portion of the crest; PSRCr: parasagittal ridge of the crest; SLT: supralabial tubercle; MP: median plain of the crest; PP: parietal plain of the crest. Note that in both the three-tuberculated and four-tuberculated state, a total of four tubercles are present, but in the three-tuberculated state, one of these tubercles is not laterally connected to the crest.
FIGURE 4. 50 in Description of a new pygmy chameleon (Chamaeleonidae: Brookesia) from central Madagascar
FIGURE 4. 50%-majority consensus tree derived from a Bayesian inference analysis of 590 bp of the mitochondrial ND2 gene. Brookesia minima was used as outgroup. Bayesian posterior probabilities are followed by the bootstrap support values>50 from Maximum Parsimony analysis. Sequences of the B. decaryi group retrieved from Genbank are marked with their accession numbers. The map indicates the sampling localities of the specimens of the B. decaryi group.
FIGURE 3 in Description of a new pygmy chameleon (Chamaeleonidae: Brookesia) from central Madagascar
FIGURE 3. (A–B) Photographs of B. brunoi sp. nov. (not collected) in its natural habitat in Anja Reserve during the day. The picture in (A) highlights the mosaic of whitish, beige and brown areas on the body of the specimens that characterise the life coloration of the species. This coloration can be interpreted as plant, stick and dried bark debris mimesis.

Figure 3. Phylogenetic relationships among species of the Brookesia minima group based on nuclear and concatenated DNA sequences. Phylograms (50% majority rule consensus trees) from Bayesian inference analyses of DNA sequence alignments of (a) the nuclear genes CMOS (846 bp) and (b) RAG1 (1522 bp). (c) Phylogram from BI analysis of concatenated DNA sequences of the nuclear genes CMOS (846 bp) and RAG1 (1522 bp), and the mitochondrial genes ND2 (568 bp) and 16S (580 bp). (d) Brookesia portion of the Bayesian chronogram derived from the BEAST analyses of all four concatenated genes (see Supporting Information S1 for full chronogram with all outgroups). Posterior probabilities are indicated above branches, and bars represent 95% HPDs for mean date estimates. Units on scale are millions of years. Species of the northern clade (B. tuberculata plus the four new species described herein) are marked in colour. The trees were rooted with Brookesia nasus, and including B. brygooi and B. superciliaris as hierarchical outgroups (not shown). A, B and C refer to major clades as discussed in the text. Asterisks denote posterior probabilities of 1.0. doi:10.1371/journal.pone.0031314.g003

Figure 1 in Rivaling the World's Smallest Reptiles: Discovery of Miniaturized and Microendemic New Species of Leaf Chameleons (Brookesia) from Northern Madagascar
Figure 1. Map of northern Madagascar showing distribution of species of the Brookesia minima group. Type localities in bold, B. dentata, B. exarmata, B. karchei, B. peyrierasi, and B. ramanantsoai not included, because their ranges are located further south; see inset maps in Fig. 2. Orange (dry forest) and green (rainforest) show remaining primary vegetation in 2003–2006, modified from the Madagascar Vegetation Mapping Project (http://www.vegmad.org). doi:10.1371/journal.pone.0031314.g001
Figure 6 in Rivaling the World's Smallest Reptiles: Discovery of Miniaturized and Microendemic New Species of Leaf Chameleons (Brookesia) from Northern Madagascar
Figure 6. Hemipenes of species in the Brookesia minima group. The photos show for each species, a general view of the organs and a close-up. For B. desperata, the inset picture shows a non-turgid everted hemipenis where the two apex projections are very prominent. Note that also several other of the shown preparations are not fully turgid, especially in B. ramanantsoai and B. micra. In two other species (B. confidens and B. tristis) the shown hemipenes might not be fully everted. doi:10.1371/journal.pone.0031314.g006
Figure 4 in Rivaling the World's Smallest Reptiles: Discovery of Miniaturized and Microendemic New Species of Leaf Chameleons (Brookesia) from Northern Madagascar
