Amphisbaena prunicolor: The Plum-Colored Worm Lizard
The plum-colored worm lizard, scientifically designated as Amphisbaena prunicolor, is a species of amphisbaenian native to South America. This reptile is recognized for its distinctive coloration and moderate size within its genus. It inhabits regions across Argentina, Brazil, and Paraguay, contributing to the biodiversity of these South American countries.
Taxonomy and Description
Formally described in 1885, Amphisbaena prunicolor has undergone taxonomic revisions throughout its history. It is characterized as a moderately large and slender species, with adults typically reaching a snout-vent length between 141.0 and 238.0 millimeters (approximately 5.55 to 9.37 inches). The dorsal side of the lizard is predominantly a uniform dark purplish-brown, often with a similarly colored tail. The ventral side presents a more variable appearance, being a mix of white and purplish-brown scales. The distribution of white coloration can range from the snout to the tail tip, or be concentrated around the head and throat. In some individuals, these contrasting scales on the underside create a striking checkerboard pattern.
Distribution and Habitat
Amphisbaena prunicolor is found in Argentina, Paraguay, and Brazil. Within Argentina, it has been recorded in the provinces of Corrientes and Misiones, while in Paraguay, it is known from the department of Itapúa. In Brazil, its range extends from Espírito Santo in the south to Rio Grande do Sul. Specific details regarding its preferred microhabitat within these regions are not extensively documented, though its classification as a worm lizard suggests a fossorial or semi-fossorial lifestyle.
Ecology and Behavior
Information regarding the diet and specific behavioral traits of Amphisbaena prunicolor is limited in available records. However, it is known to be preyed upon by the plush-crested jay, indicating its place within the local food web. Further research would be beneficial to fully understand its ecological role, reproductive strategies, and daily activities.
