DiagnosisDiagnosis. “A Trimetopon with two prefrontals. Allied to T. barbouri Dunn and to T. viquezi Dunn; differs from the first in having more dorsals (17) and more ventrals (153-161); differs from the second in having paired light spots on nape, in lacking a dark streak on scale row 4, in that extension of white neck-color dorsally does not involve seventh upper labial.”
