Comment | Has been considered as a synonym of X. argenteus by most authors but revalidated by KEISER (1989).
According to Article 53.3 of the Code, Philodryas boulengeri Werner 1909, a junior synonym of Philodryas mattogrossensis Koslowsky, 1898 and Philodryas boulengeri (Procter, 1923) are secondary homonyms because both meet the criterion of availability (see Articles 10.6 and 11 of the Code). According to the Principle of Priority (Article 23), Philodryas boulengeri (Procter, 1923) is the junior secondary homonym. Considering that both names do not fall into any of the exceptions listed in Articles 23.7.3, 23.8 and 23.9, and that Philodryas boulengeri (Procter, 1923) has no known available and potentially valid junior synonyms, its specific epithet must be replaced by a new substitution name (Articles 57.3.1. and 59.1) [GRAZZIOTIN et al. 2012]. The homonymy was resolved by the resurrection of Xenoxybelis by MELO-SAMPAIO et al. 2020, hence the name returns to boulengeri.
Habitat: fully arboreal (Harrington et al. 2018). |
