Figure 1. Molecular differentiation of species in the Calumma boettgeri complex. A, maximum likelihood tree based on DNA sequences of the mitochondrial ND2 gene (515 bp). Numbers at nodes are bootstrap proportions expressed as a percentage (2000 replicates) followed by posterior probabilities from an independent Bayesian inference analysis of the same data set. GenBank accession numbers are given for each sequence included. B, haplotype network estimated from sequences of the nuclear CMOS gene (410 bp). Black dots represent additional mutational steps, and species are assigned the same colours as in the mitochondrial DNA tree.

FIGURE 5. Morphological comparison of Brookesia nofy sp. nov. and B. ramanantsoai based on preserved specimens. The upper images show (A) the male holotype of B. nofy sp. nov. (ZSM 30/2024) and (B) a comparative male specimen of B. ramamantsoai (ZSM 10/2009; *image mirrored) in lateral view to illustrate the relatively longer tail in B. ramanantsoai. The lower images show (C–D) dorsal views of the heads of the B. nofy sp. nov. holotype and four comparative B. ramanantsoai specimens; in the upper row (C), the specifically distinct parts of the elevated cephalic ridges are indicated by blue respectively purple lines: a U-structure and two central ridges in B. nofy sp. nov. vs. three parallel longitudinal ridges in B. ramanantsoai. Scale bars = 1 mm.
