Nayarit Coralsnake

Micrurus proximans is small for its genus. Adults usually have a total length (tail included) of 40–50 cm (16–20 in). The maximum recorded total length is 56.5 cm (22.2 in). Like many other species of New World coral snakes, the color pattern consist of red, black, and white (or yellow) rings, with the black rings not arranged in triads. Unlike other species, the females of M. proximans have several black rings interrupted ventrally. The white (or yellow) rings are narrowest (1 dorsal and 1 ventral wide). The black rings are wider (2–3 dorsal and 2–3 ventrals wide). The red rings are widest, two times or more wider than the black rings, depending on the number of black rings present. Males have 21–24 black rings on the body. Females have 17–22 black rings on the body, 3–10 of which are complete. Males have supraanal tubercles, and have 202–207 ventrals and 47–53 subcaudals. Females have 210–218 ventrals and 36–42 subcaudals.

Micrurus proximans is found in western Mexico, in the Mexican states of Colima, Jalisco, and Nayarit.

Micrurus proximans is known to prey upon Rena dugesii, and probably upon other small snakes.
