The Munoa worm lizard (Amphisbaena munoai) is a small species of amphisbaenian in the family Amphisbaenidae of the reptilian order Squamata.[2][3] The species is native to southern South America.
Etymology
The specific name, munoai, is in honor of Uruguayan zoologist Juan Ignacio Muñoa (1925–1960).[4]
Description
Amphisbaena munoai has a rounded head. The body annuli number 202–218, and the caudal annuli number 18–25. There are 10–14 segments in an annulus at midbody. There are four precloacal pores.[2]
Habitat
The preferred natural habitat of Amphisbaena munoai is grassland, at elevations of 100–500 m (330–1,640 ft).[1]
Behavior
Amphisbaena munoai is terrestrial and fossorial.[1] It can be found hiding under stones or decomposing bark.[3] Hiding under stones allows the amphisbaenian to raise its body temperature without exposing itself to predators.[3]
Diet
The main component of the diet of Amphisbaena munoai consists of termites, but it also consumes various types of small insect larvae.[3]
Reproduction
Amphisbaena munoai has a seasonal reproductive cycle. Females are able to be fertilized between June and October while males display a high testicle volume during this period.[3] Females carry eggs from November to December and thus it is believed that copulation occurs from September to November.[3] The eggs of A. munoai are frequently found in ant nests.[3] Sexually mature males have a significantly smaller snout-vent length than sexually mature females.[3]
Geographic distribution
Amphisbaena munoai can be found in the pampas biome of southern Brazil, a temperate climate, and in Uruguay.[2][3]
