Trachylepis brevicollis (Wiegmann, 1837)

Size

Trachylepis brevicollis is a relatively large, robust skink that reaches an approximate snout–vent length of 140 mm.

Body and Limb Structure

It has a cylindrical body with well-developed limbs.

Scale Characteristics

Its dorsal and lateral scales are strongly keeled, often with double keels, which gives its skin a rough texture.

Head Scale Features

The species has a broad head, with five supralabial scales positioned anterior to the eye, and the first supraocular scale contacts the frontal scale.

Color Variation Overview

Trachylepis brevicollis has variable coloration.

Juvenile and Adult Coloration

Juveniles typically show bold dark and light patterning, while adults are usually more uniformly brown or grey.

Adult Male Color Polymorphism

In some populations, particularly those in Arabia, adult males may display orange or reddish coloration along their flanks and body sides.

Geographic Range

This species is found across Sudan, South Sudan, Eritrea, Ethiopia, Somalia, Kenya, Uganda, Tanzania, Yemen, Saudi Arabia, and Oman.

Habitat Types

It lives in open and semi-arid environments, including savanna, scrubland, rocky terrain, agricultural areas, and disturbed habitats.

Microhabitat Preferences

It is often found on the ground, in low vegetation, and within human-modified landscapes.

Activity Pattern and Locomotion

Trachylepis brevicollis is diurnal and primarily terrestrial.

Basking and Foraging Behavior

Individuals are commonly seen basking in sunlight and actively foraging during the day.

Diet Assumptions

Like other species in the Trachylepis genus, it is presumed to be insectivorous and feeds mainly on small invertebrates, though no detailed studies of its diet have been completed.

Reproductive Mode

This species is ovoviviparous: females give birth to live young instead of laying eggs, a reproductive mode that is typical of many African mabuyine skinks.
