This relatively small snake has a wide range and is a major source of snakebite in Argentina. It was named after German naturalist Prince Maximilian of Wied-Neuwied (1782-1867), who made important collections in Brazil (1815-1817).〔 Twelve subspecies are currently recognized, including the nominate subspecies described here. ==Description== Adults average in total length, but may grow to as much as .〔 Head scalation includes 7-11 keeled intrasupraoculars (rarely 12 or as few as five), 9-13 sublabials (usually 10-11) and seven to eight supralabials (rarely seven or 10), the second of which is not fused with and usually separated from the prelacunal. Two rows of small scales usually separate the subocular and fourth supralabial scales. At midbody the 22-29 (usually 25-27) rows of dorsal scales〔 are strongly keeled.〔 The ventral scales number 158-179 and 164-185 in males and females, respectively, while the subcaudal scales are divided and number 39-56 or 34-51 in males or females.〔 The color pattern consists of a brown or dark-brown ground color overlaid with a series of 16-27 dark brown or black dorsolateral blotches. The blotches are edged in white and may be trapezoidal, triangular, subtriangular, or headphone-shaped and oppose each other middorsally. The belly is white or yellow with gray speckling. Juveniles have a white tail tip.〔 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「Bothrops neuwiedi」の詳細全文を読む スポンサード リンク
