CommentDiagnosis: This species is characterized by the following combination of characters: divided internasals and prefrontals; dorsal coloration usually of two series of dots on the anterior third and a tessellated pattern of spots afterwards, or a tessellated pattern of spots along body over brown color. Venter is yellowish with paired black dots along the belly. Conopsis amphisticha shares its characteristic dorsal pattern of spots with Conopsis biserialis, with which it can be confused, but their geographic ranges do not overlap.
