Elapoidea
The Elapoidea are a Superfamily (biology), superfamily of snakes in the clade Colubroides, traditionally comprising the families Lamprophiidae and Elapidae. Advanced genomic sequence studies, however, have found lamprophiids to be paraphyletic in respect to elapids. In describing the subfamily Cyclocorinae, Weinell et al. (2017) suggested some or all subfamilies of Lamprophiidae should be reevaluated at full family status as a way to prevent the alternative, which is classifying them as elapids. This was followed in later studies such as Zaher et al. (2019). The Reptile Database considers Elapoidea to be synonymous with its sister group Colubroidea (in contrast to other studies that distinguish between both), as it does not recognize the division of Colubridae into multiple families that comprise Colubroidea, and thus instead considers Colubroidea to be composed of Colubridae + the multiple families comprising Elapoidea. Below is the phylogeny of Elapoidea after Weinell et al. ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamprophiidae
The Lamprophiidae are a family of snakes found throughout much of Africa, including the Seychelles. There are 89 species as of July 2022. Biology Lamprophiids are a very diverse group of snakes. Many are terrestrial but some are fossorial (e.g. ''Amblyodipsas'') or semi-aquatic (e.g. ''Lycodonomorphus''). Some are fast-moving (e.g. ''Psammophis'') whereas others are slow (e.g. ''Duberria''). They are found in deserts, grasslands, tropical forests and mountains. Together they feed on mammals, birds, reptiles, amphibians, fish, and invertebrates. Some species use constriction to subdue their prey (e.g. ''Boaedon''). When other snake families were formerly included within the Lamprophiidae, they were considered even more diverse in biology, although this is now known to not be the case. Most species are oviparous. Classification Most lamprophiids were historically considered to be members of the subfamily Lamprophiinae in the family Colubridae. The following classification follows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colubroides
The Colubroides are a clade in the suborder Serpentes ( snakes). It contains over 85% of all the extant species of snakes. The largest family is Colubridae, but it also includes at least six other families, at least four of which were once classified as "Colubridae" before molecular phylogenetics helped in understanding their relationships. It has been found to be monophyletic. Morphological synapomorphies are defined as such from Zaher et al. (2009): Loss of the right carotid artery; intercostal arteries arising from the dorsal aorta throughout the trunk at intervals of several body segments; specialized expanded costal cartilages; presence of a muscle protractor laryngeus; separate muscle protractor quadrati; separate spinalis and semispinalis portion in the epaxial trunk; spinules or spines covering the hemipenial body. Traditionally, the name "Colubroidea Colubroidea is a superfamily of snakes in the clade Colubroides that includes Colubridae, with some studies spl ...

Colubroidea
Colubroidea is a superfamily of snakes in the clade Colubroides that includes Colubridae, with some studies splitting Colubridae into multiple families that make up Colubroidea. Historically, Colubroidea also included other caenophidian snakes such as cobras and vipers, as these snakes form a clade. However these groups are now divided into several distinct, but related, families. Zaher et al. (2009) proposed to redefine Colubroidea for colubrids and related families, while designating Colubroides as the group containing vipers and cobras as well as colubroids. The ReptileDatabase considers Colubroidea to be composed of Colubridae and the members of its sister group, Elapoidea, and does not recognize the division of Colubridae into multiple families.

Cyclocorinae
Cyclocoridae is a family of elapoid snakes endemic to the Philippines. Taxonomy It was initially erected as a subfamily (Cyclocorinae) in 2017 to house four enigmatic, endemic genera containing seven species and one then-undescribed lineage that are more closely related to one another than to members of the families Atractaspididae or to other former subfamilies of the Lamprophiidae. The undescribed lineage was described in 2020 as the new genus '' Levitonius''. Previously placed within the Colubridae, a 2017 study by Weinell et al. found strong support the monophyly of Cyclocorinae within Lamprophiidae, but its position relative to the other subfamilies of Lamprophiidae is not resolved. Cyclocorinae was found to be a possible sister group to the Atractaspidinae. In 2019, they were reclassified as a distinct family Cyclocoridae, alongside many former members of Lamprophiidae, as Lamprophiidae was found to be otherwise paraphyletic with respect to Elapidae.
