ABSTRACT Recent molecular studies have effectively resolved the phylogeny of most of the modern snakes. Notwithstanding this, the taxonomy at the family level is seen to be inconsistent between major clades, with family level groups of similar divergence times being classified by single authors variously as genera, subfamilies and families within single given papers. To correct the inconsistencies, some of the lower ranked groups are elevated to match the others already accorded family status. This also brings the taxonomy and nomenclature of the snakes more into line with other vertebrate groups, including most notably the birds and placental mammals. For the majority of affected clades there are already available names and each simply converts from subfamily to family. However, four well-established groups until now have not been formally named. Instead they have been shunted between other family-level groups, sometimes in placements that do not match the evidence. In view of recently published phylogenies which clearly show that these taxa should be placed separately, regardless of their very ancient affinities, they are named herein according to the Zoological Code (Ride et al. 1999). A further two groups, until now classified as being within the Pseudoxenodontinae and Colubrinae, both of which are now elevated to family status are removed from these and placed within their own families due to their early divergence. One of these in turn is divided into two newly named tribes.

INTRODUCTION Unfortunately the taxonomy and nomenclature have not The currently recognized taxonomy of the extant snakes kept up with the results produced by molecular biologists, is a synthesis of countless studies over the past two due in part to the relative speed and ease with which centuries. large amounts of genetic material can be processed.

Charlespiersonserpeniidae fam. nov. (this paper, Also notable was that Pyron et al. (2011) did not description below) recognize the well defined subgroups within the Elapidae Colubridae as subfamilies, as had been done for the mega-families Crotalidae Lamprophiidae and Colubridae. Dipsadidae Now in fairness to the authors, a detailed taxonomy was not their objective, however it is raised here as argument Elapidae for the need to have a consistent taxonomy and Grayiidae nomenclature that other herpetologists can use. Homalopsidae In summary, I see it as preferable to elevate the Homoroselapidae approximately 22 groups of snakes with family level Micrelapiidae fam. nov. (this paper, description divergences to full family level in nomenclature rather below) than the subsuming of the majority into what could well Lamprophiidae be just two or three super-families. Natricidae This preference is also noted in view of the fact that increasing numbers of taxonomists are also using the Oxyrhabdiumiidae fam. nov. (this paper, description tribe level of nomenclature to identify groups of like below) genera, thereby in effect allowing for a little used level of Pareatidae grouping between genus and family to further clarify Prosymnidae phylogenetic affinities.

  • Quantifying the Conservation Value of Plantation Forests for a Madagascan Herpetofauna
    Herpetological Conservation and Biology 14(1):269–287. Submitted: 6 March 2018; Accepted: 28 March 2019; Published: 30 April 2019. QUANTIFYING THE CONSERVATION VALUE OF PLANTATION FORESTS FOR A MADAGASCAN HERPETOFAUNA BETH EVANS Madagascar Research and Conservation Institute, Nosy Komba, Madagascar current address: 121 Heathway, Erith, Kent DA8 3LZ, UK, email: [email protected] Abstract.—Plantations are becoming a dominant component of the forest landscape of Madagascar, yet there is very little information available regarding the implications of different forms of plantation agriculture for Madagascan reptiles and amphibians. I determined the conservation value of bamboo, secondary, open-canopy plantation, and closed-canopy plantation forests for reptiles and amphibians on the island of Nosy Komba, in the Sambirano region of north-west Madagascar. Assistants and I conducted 220 Visual Encounter Surveys between 29 January 2016 and 5 July 2017 and recorded 3,113 reptiles (32 species) and 751 amphibians (nine species). Closed-canopy plantation supported levels of alpha diversity and community compositions reflective of natural forest, including several threatened and forest-specialist species. Open-canopy plantation exhibited diminished herpetofaunal diversity and a distinct community composition dominated by disturbance-resistant generalist species. Woody tree density and bamboo density were positively correlated with herpetofaunal species richness, and plantation species richness, plantation species density, sapling density, and the proportion of wood ground cover were negatively associated with herpetofaunal diversity. I recommend the integration of closed-canopy plantations on Nosy Komba, and across wider Madagascar, to help mitigate the negative effects of secondary forest conversion for agriculture on Madagascan herpetofauna; however, it will be necessary to retain areas of natural forest to act as sources of biodiversity for agroforestry plantations.

  • Ancestral Reconstruction of Diet and Fang Condition in the Lamprophiidae: Implications for the Evolution of Venom Systems in Snakes
    Journal of Herpetology, Vol. 55, No. 1, 1–10, 2021 Copyright 2021 Society for the Study of Amphibians and Reptiles Ancestral Reconstruction of Diet and Fang Condition in the Lamprophiidae: Implications for the Evolution of Venom Systems in Snakes 1,2 1 1 HIRAL NAIK, MIMMIE M. KGADITSE, AND GRAHAM J. ALEXANDER 1School of Animal, Plant and Environmental Sciences, University of the Witwatersrand, Johannesburg. PO Wits, 2050, Gauteng, South Africa ABSTRACT.—The Colubroidea includes all venomous and some nonvenomous snakes, many of which have extraordinary dental morphology and functional capabilities. It has been proposed that the ancestral condition of the Colubroidea is venomous with tubular fangs. The venom system includes the production of venomous secretions by labial glands in the mouth and usually includes fangs for effective delivery of venom. Despite significant research on the evolution of the venom system in snakes, limited research exists on the driving forces for different fang and dental morphology at a broader phylogenetic scale. We assessed the patterns of fang and dental condition in the Lamprophiidae, a speciose family of advanced snakes within the Colubroidea, and we related fang and dental condition to diet. The Lamprophiidae is the only snake family that includes front-fanged, rear-fanged, and fangless species. We produced an ancestral reconstruction for the family and investigated the pattern of diet and fangs within the clade. We concluded that the ancestral lamprophiid was most likely rear-fanged and that the shift in dental morphology was associated with changes in diet. This pattern indicates that fang loss, and probably venom loss, has occurred multiple times within the Lamprophiidae.

A taxonomic framework for typhlopid snakes from the Caribbean and other regions (Reptilia, Squamata). Caribbean Herpetology 49:1–61. Abstract The evolutionary history and taxonomy of worm-like snakes (scolecophidians) continues to be refined as new molec- ular data are gathered and analyzed. Here we present additional evidence on the phylogeny of these snakes, from morphological data and 489 new DNA sequences, and propose a new taxonomic framework for the family Typhlopi- dae. Of 257 named species of typhlopid snakes, 92 are now placed in molecular phylogenies along with 60 addition- al species yet to be described. Afrotyphlopinae subfam. nov. is distributed almost exclusively in sub-Saharan Africa and contains three genera: Afrotyphlops, Letheobia, and Rhinotyphlops. Asiatyphlopinae subfam. nov. is distributed in Asia, Australasia, and islands of the western and southern Pacific, and includes ten genera:Acutotyphlops, Anilios, Asiatyphlops gen.

  • Biogeography of the Reptiles of the Central African Republic
    African Journal of Herpetology, 2006 55(1): 23-59. ©Herpetological Association of Africa Original article Biogeography of the Reptiles of the Central African Republic LAURENT CHIRIO AND IVAN INEICH Muséum National d’Histoire Naturelle Département de Systématique et Evolution (Reptiles) – USM 602, Case Postale 30, 25, rue Cuvier, F-75005 Paris, France This work is dedicated to the memory of our friend and colleague Jens B. Rasmussen, Curator of Reptiles at the Zoological Museum of Copenhagen, Denmark Abstract.—A large number of reptiles from the Central African Republic (CAR) were collected during recent surveys conducted over six years (October 1990 to June 1996) and deposited at the Paris Natural History Museum (MNHN). This large collection of 4873 specimens comprises 86 terrapins and tortois- es, five crocodiles, 1814 lizards, 38 amphisbaenids and 2930 snakes, totalling 183 species from 78 local- ities within the CAR. A total of 62 taxa were recorded for the first time in the CAR, the occurrence of numerous others was confirmed, and the known distribution of several taxa is greatly extended. Based on this material and an additional six species known to occur in, or immediately adjacent to, the coun- try from other sources, we present a biogeographical analysis of the 189 species of reptiles in the CAR. Key words.—Central African Republic, reptile fauna, biogeography, distribution. he majority of African countries have been improved; known distributions of many species Tthe subject of several reptile studies (see are greatly expanded and distributions of some for example LeBreton 1999 for Cameroon). species are questioned in light of our results.
