Anguis veronensis
Anguis veronensis·Anguidae
Anguis veronensis, also known as the Italian slow worm, is a legless lizard species found across Italy and parts of southeastern France. It is distinguished from similar species by its relatively longer tail, more subcaudal scales, and a more robust head, although genetic analysis is often required for definitive identification. This species inhabits a variety of environments, from forest-steppes and urban areas to Mediterranean shrublands, and is primarily active during the day or twilight.

About Anguis veronensis
Anguis veronensis: The Italian Slow Worm
Anguis veronensis, commonly referred to as the Italian slow worm, is a species of legless lizard native to the Anguidae family. Its distribution is primarily confined to Italy and the southeastern regions of France. First scientifically described in 1818, it was initially named after Verona, Italy, where specimens were collected. Historically, individuals from the Italian Peninsula were often mistaken for the common slow worm, Anguis fragilis, due to their close morphological similarity. However, distinct genetic and morphological features led to its re-establishment as a separate species in 2013, eventually being designated by its oldest available scientific name, Anguis veronensis.
Taxonomy and Identification
Distinguishing Anguis veronensis from other closely related species within the genus Anguis can be challenging based solely on external morphology. Genetic analysis is often necessary for definitive identification. Morphological studies have revealed key differences, including a relatively longer tail in both sexes of Anguis veronensis, a higher number of subcaudal scales, and a more robust head structure compared to Anguis fragilis. Variations in coloration and the presence of external ear openings show insufficient distinction for reliable identification between these species.
Distribution and Habitat
The Italian slow worm is observed across Italy, with a notable presence in the northern parts of the country. Its range extends into southeastern mainland France, specifically the Provence-Alpes-Côte d'Azur region, and it has also been documented on the Mediterranean island of Ile Sainte-Marguerite. Some experts suggest its distribution may also include the southern fringes of Switzerland. The species occupies a diverse array of habitats. In northern and northeastern Italy, it is found in forest-steppe, steppe, and ruderal environments, with some individuals adapting to urban settings. Central and southern Italian populations are more often found near the borders of oak and beech forests, as well as on the sand dunes characteristic of Mediterranean maquis shrubland. Anguis veronensis has been recorded at altitudes ranging from sea level up to over 2,000 meters in the Alps.
Behavior and Ecology
The activity patterns of Anguis veronensis vary geographically. The majority of individuals are primarily diurnal, meaning they are active during the daytime, or occasionally exhibit crepuscular activity, being active at twilight. However, populations found in Mediterranean regions tend to be more crepuscular and sometimes nocturnal, showing activity during the night. In certain areas, such as northeastern Italy and Slovenia, Anguis veronensis has been observed to hybridize with the common slow worm, Anguis fragilis.

Frequently Asked Questions
What is the Italian slow worm?
The Italian slow worm, scientifically known as Anguis veronensis, is a species of legless lizard belonging to the Anguidae family. It is native to Italy and parts of southeastern France.
How can the Italian slow worm be identified?
While morphologically similar to other slow worms, Anguis veronensis can be differentiated by its relatively longer tail, a greater number of subcaudal scales, and a more robust head shape. Genetic analysis is often the most reliable method for distinguishing it from closely related species.
Where does the Italian slow worm live?
This species is found throughout the Italian Peninsula, with a higher concentration in the north. It also inhabits southeastern mainland France, specifically the Provence-Alpes-Côte d'Azur region, and has been confirmed on the island of Ile Sainte-Marguerite.
What kind of habitats does Anguis veronensis prefer?
Anguis veronensis occupies a range of habitats. Northern populations are found in forest-steppes, steppes, and ruderal areas, sometimes including urban environments. In central and southern Italy, they are more commonly found at the edges of oak and beech forests, and in Mediterranean maquis shrubland on sand dunes.
When is the Italian slow worm most active?
The activity patterns vary by region. Most individuals are primarily diurnal (active during the day) or occasionally crepuscular (active at twilight). However, populations in Mediterranean areas tend to be mostly crepuscular and sometimes nocturnal (active at night).
Does the Italian slow worm hybridize with other species?
Yes, in areas of contact, particularly in northeastern Italy and Slovenia, Anguis veronensis can hybridize with the common slow worm, Anguis fragilis.
