Leposternon microcephalum, also known commonly as the smallhead worm lizard, is a species of amphisbaenian in the family Amphisbaenidae in the reptilian order Squamata. The species is endemic to South America.

Geographic range

L. microcephalum is found in southern Brazil, Bolivia, Paraguay, Uruguay, and northern Argentina.[1][2] It occurs in the Itatiaia National Park between Rio de Janeiro and Minas Gerais in Brazil.[3]

Ecology

Amphisbaenians have few predators due to their fossorial habits, powerful bite, and defensive tactics. However, some snakes have been found feeding on amphisbaenians including L. microcephalum.[3]

Reproduction

L. microcephalum is oviparous.[2]
