CommentDiagnosis.– Macrocalamus vogeli is characterized by (1) a broad dark ventrolateral stripe on each side, bordered dorsally by a narrower yellow stripe; (2) a broad oblique yellow strike behind the head, followed by two narrow, faint oblique lines on the body; (3) small, yellow, dark-edged ocelli on anterior part of the body; (4) a yellow venter heavily powdered with brownish-black dots; and (5) a median stripe below the tail. This species has both a single dark ventrolateral stripe and a yellow venter that is heavily speckled with black. Macrocalamus vogeli differs from Macrocalamus lateralis by (1) the presence of a loreal scale, (2) the dorsal pattern, with much reduced ocelli, no light dorsolateral stripe and a single dark ventrolateral stripe, (3) the color of the venter, and (4) by higher numbers of ventral and subcaudal scales. The new species differs from Macrocalamus chanardi by (1) the color and pattern of the venter, yellow and heavily speckled vs. red or orange and uniform in M. chanardi, and (2) the dorsal pattern with reduced ocelli (large in M. chanardi), and (3) a much higher number of ventral scales, with 125 in the holotype vs. 104-114 in Macrocalamus chanardi.
Lastly, Macrocalamus vogeli is distinguished from M. schulzi by the (1) the presence of a ventrolateral stripe (absent in M. schulzi) and (2) the pattern of the venter (uniform in M. schulzi, vs. strongly speckled in M. vogeli.) Scalation characters are otherwise rather similar. 
EtymologyNamed after Dr. Gernot Vogel (Society for Southeast Asian Herpetology, Heidelberg), for his contributions to the taxonomy of the genus Macrocalamus and to the herpetology of Southeast Asia in general.
