Figures

Figure 1. – A: The different patterns of interorbital scales (IOS); head in dorsal view. B: Size of the jaw; head in lateral view. C: Auxiliary scales on flanks.

Figure 2 (see also following page). – A: Bayesian tree of the cytochrome c oxidase subunit (COI; 452 bp) for sequenced specimens of Butis. Numbers at each node represent posterior probabilities. B: Barcoding NJ K2P tree of the COI gene (196 bp) for sequenced specimens of Butis including the holotype of Butis humeralis from the MNHN collection. Numbers at each node represent bootstrap values. C, D: Barcoding NJ K2P trees of the 12S and the 16S genes (129 and 270 bp respectively) for sequenced specimens of Butis collected during the 19th century from the MNHN collection including a paratype of B. audebertae (MNHN A-1503). Numbers at each node represent bootstrap values. [A high resolution version is available online.]
