''Hylomyscus endorobae'' is a species of rodent of the genus ''Hylomyscus'' that is found only in select portions of the wet East African montane forests of the Kenyan Rift mountains of southwestern Kenya and Tanzania, and only at elevations above .〔 It was described in 1910 and initially considered a distinct species. It was later reclassified as a synonym of ''Hylomyscus denniae'', thought to be a widespread species but with a disjunct distribution among the tropical wet forests of a broader afromontane biotic region.〔 It had also been interpreted as a small form of the genus ''Praomys''.〔 In 2006, ''Hylomyscus'' and ''Praomys'' were confirmed to be distinct genus-group taxa, and ''H. endorobae'' was again recognized as a distinct species. Twelve species of ''Hylomyscus'' are currently recognized, provisionally arranged in six groups. ''H. endorobae'' together with ''H. denniae'' and ''H. vulcanorum'' comprise the ''H. denniae'' group. These three species are quite similar, and they occupy similar habitats that are in relative close proximity to one another.〔 However, because they exclusively inhabit wet montane forests above 2,000 m, they are geographically isolated from one another, in much the same way that some species become endemic to particular islands. ''H. endorobae'' appears to be endemic to the Kenyan Rift mountains east of Lake Victoria from Mount Elgon to Mount Kenya. ''H. denniae'', on the other hand, is endemic to the Ruwenzori Mountains, along the border between Uganda and the Democratic Republic of the Congo, while ''H. vulcanorum'' is found just south of the Equator, in Burundi, Rwanda, and the D.R. Congo.〔 There are eight characteristics that distinguish the various members of the ''Hylomyscus'' genus. For example, ''H. endorobae'' can be distinguished because it is larger than ''H. denniae'', with a broader skull and larger molars. ==References== 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「Hylomyscus endorobae」の詳細全文を読む スポンサード リンク
