| Diagnosis | Diagnosis: Coniophanes michoacanensis differs from other members of the genus, except C. piceivittis and C. schmidti, in possessing a higher number of dorsal scale rows at midbody (25; vs. 21 dorsal scale rows or less in the other species), and in having 9/9 infralabials (10/10 in C. piceivittis, C. schmidti, and C. taylori, with rare exceptions, Table 1 in FLORES-VILLELA & SMITH 2009). It differs from C. piceivittis and C. schmidti in having a narrow dark vertebral stripe (only three and two half scales wide; dark vertebral stripe five and two half scales wide in C. piceivittis, from five and two half scales to seven and two half scales in C. schmidti, and five and two half scales in C. taylori). Coniophanes michoacanensis further differs from C. piceivittis and C. taylori in having a narrow dark lateral stripe occupying only one and two half scales (dark lateral stripe occupying four and two half scales in C. piceivittis, and two and one half scales to three in C. taylori). Coniophanes michoacanensis differs additionally from C. schmidti in that the lower edge of the lateral stripes contrast sharply with the ground color, C. piceivittis and C. taylori are similar to C. michoacanensis in this character.
