Currently, five subspecies are recognized, including the nominate subspecies described here. Recent taxonomic work suggests that most of these should be considered as separate species. IUCN has already evaluated ''O. m. makazayazaya'' as ''Ovophis makazayazaya''. ==Description== Total length of males 49 cm (19¼ inches), of females 110 cm (43¼ inches); tail length of males 8 cm (3⅛ inches), of females 15 cm (5⅞ inches).〔Leviton AE, Wogan GOU, Koo MS, Zug GR, Lucas RS, Vindum JV. 2003.

The crown is covered by small scales rather than large shields, while the scales are usually smooth, feebly imbricate. The first upper labial is not fused to the nasal and is completely separated by a suture. The supraoculars are large, 5-9 scales in a line between them. The internasals are usually not in contact with one another, separated by 2 small suprapostrostral scales. There are 7-10 upper labials, the second of which is usually fused to the scale bordering the facial sensory pit anteriorly. The fourth and fifth upper labials are beneath the eye, but separated from orbit by a series of 2-4 small scales.〔 The body is stout. The dorsal scales are smooth or weakly keeled, in 23-25, occasionally in 19 or 21 longitudinal rows at midbody. Ventral scales and subcaudals (Myanmar, northeastern India and adjacent areas of China and Thailand) 137-176 and 36-62 respectively, subcaudals mixed paired and single, occasionally all unpaired (ventrals and subcaudals for southern China, Vietnam, Laos: 127-144 and 36-54, and Malaysian Peninsula: 133-137 and 22-28 respectively (Smith 1943:509 )).〔 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「Ovophis monticola」の詳細全文を読む スポンサード リンク
