|Diagnosis||Diagnosis: Hypsilurus capreolatus is a small species for the genus (adult males, 97–115 mm; adult females, 100–119 mm) characterized by having the unique combination of small, homogeneous dorsal scales; a nuchal crest with small, lanceolate scales approximately one-third diameter of tympanum (range, 0.15–0.69; mean, 0.31), separated from a dorsal crest of very low, largely overlapping scales; 114–158 scale rows around mid-body (mean, 128.6); a row of enlarged submandibles extending from mental to below rictus; a maximum of three to four scales present between infralabials and submandibles; scales of gular sac small, smooth or tuberculate, juxtaposed to subimbricate, and of similar size anteriorly and posteriorly, lacking enlarged scales anteriorly or medially, and with 30–42 (mean, 36.0) rows of gular scales extending between submandibular scale rows at level of the posterior-most infralabials; weakly enlarged scales at rictus and below tympanum; HW/SV = 0.16–0.22 (mean, 0.19); TY/EY = 0.51–0.94 (mean, 0.62); with a dorsal pattern of five long, brown chevrons across the dorsum between the nuchal crest and hindlimbs, these separated by four light chevrons (Fig. 1); and throat and sides of neck spotted with black.|
|Etymology||Named after the Latin masculine adjective of ‘‘capreolus’’ meaning ‘‘rafter,’’ from which is derived the French (and, hence, English) ‘‘chevron.’’ It refers to the diagnostic pattern of this species.|
