Description

Micrurus scutiventris is a very small species of New World coral snake. Adults usually have a total length (tail included) of less than 40 cm (16 in). The holotype has a total length of 44.5 cm (17.5 in), which is the maximum recorded total length.[3]

Dorsally, M. scutiventris is black, except for a yellow or orange band across the top of the head. Ventrally, it is black with large yellow oval spots. Each spot is about four ventrals long and may extend onto the first two rows of dorsal scales. The black spaces between the spots are also about four ventrals long. Both sexes have 26–34 ventral spots on the body. The tail has one or two red rings.[3]

Males have 219–243 ventrals and 21–27 subcaudals, and females have 253–274 ventrals and 15–20 subcaudals.[3]

Geographic distribution

Micrurus scutiventris is found in Brazil, Colombia, Ecuador, and Peru.[2]

Habitat

The preferred natural habitat of Micrurus scutiventris is forest, at elevations of 60–1,200 m (200–3,940 ft).[1]

Behavior

Micrurus scutiventris is terrestrial, semi-fossorial, and nocturnal.[1]

Diet

Micrurus scutiventris preys upon small burrowing lizards, including species of the genus Bachia.[3]

Reproduction

Micrurus scutiventris is oviparous.[2]

Etymology

The specific names of two synonyms, karlschmidti and schmidti, are both in honor of American herpetologist Karl Patterson Schmidt.[2][3]
