''Oplurus'' is a genus of Malagasy iguanian lizards, most of which are rock-dwelling terrestrial species. The sister genus to ''Oplurus'' is ''Chalarodon'', which contains one species: ''Chalarodon madagascariensis'', which is a terrestrial iguana and easily distinguished from ''Oplurus'' by its smaller size and the presence of a distinct dorsal crest. ==Species== The six or seven species in the genus ''Oplurus'' comprise two distinct clades. 〔 〕 〔 〕 *Spiny-tailed arboreal clade: * *Merrem's Madagascar swift (''Oplurus cyclurus'') * *Collared iguanid (''Oplurus cuvieri'') *Saxicolous (rock dwelling) clade: * *Madagascar blue iguana (''Oplurus fierinensis'') (greyish-blue without dark dorsal bands) * *Grandidier's Madagascar swift (''Oplurus grandidieri'' (with light mid-dorsal band) * *Duméril's Madagascar swift (''Oplurus quadrimaculatus'') (with four dorsal bands, dorsal scales coarsely granular) * *Marked Madagascar swift (''Oplurus saxicola'') (different darker color pattern, dorsal scales finely granular)〔 〕 Because of differences is appearance (i.e. the lack of a black neck band), possibly a larger body, and its geographic isolation, the form of ''Oplurus cuvieri'' species found on the Comoro archipelago has recently been given full species rank, as ''Oplurus comorensis'' (Meirte 2004). However the molecular phylogeny research concludes that this full species status is unwarranted.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oplurus」の詳細全文を読む スポンサード リンク
