| Distribution | W Madagascar (Nosy Komba) Type locality: Ampijoroa (Ankarafantsika Reserve) |
| Reproduction | viviparous (not imputed, fide Zimin et al. 2022) |
| Types | Holotype: ZSM 804/2001, adult male; paratypes: MNHN 1978.96 and 1978.97, subadult |
| Diagnosis | Diagnosis: Sanzinia madagascariensis volontany differs from S. m. madagascariensis by a predominantly brownish adult colouration (predominantly greenish in S. m. m.) and a high genetic differentiation in the 16S rRNA gene (Tab. 1) which is nearly twice as high as between Acrantophis madagascariensis and A. dumerilii. Morphologically, there is a tendency of the new subspecies to have a lower number of infralabials, and possibly of supralabials and perioculars (see Tab. 3), but none of these characters can be used as a reliably diagnostic difference (Vences & Glaw 2003: 194) Additional details (2193 characters) are available for collaborators and contributors. Please contact us for details. |
| Comment | Subspecies: Both (sub-) species are parapatric and their distribution areas approach each other only in the very south of Madagascar. Some authors suggested that S. m. volontany should be elevated to specific status despite an apparent lack of diagnostic morphological differences (Orozco-Terwengel et al., 2008, Reynolds et al. 2014). Synonymy: Listed as synonym of Sanzinia madagascariensis by WALLACH et al. 2014: 661. |
| Etymology | The Malagasy word “volontany” means brown and refers to the predominant ground colour of the subspecies. It is used as invariable noun in apposition. |
