Definition
Adolfus alleni is a species of lizard belonging to the family Lacertidae. It is a reptile native to East Africa.
Overview
The species is part of the genus Adolfus, which comprises several forest-dwelling lacertid lizards found in the highland regions of the African Great Rift Valley. A. alleni is known from montane and submontane forest habitats, where it is primarily active during daylight hours. The species is presumed to be insectivorous, feeding on a variety of small arthropods. Conservation assessments have been limited; however, habitat loss due to deforestation is considered a potential threat.
Etymology / Origin
The specific epithet alleni honors an individual with the surname Allen, who is recognized in the original description for contributions to herpetology or to the collection of the type specimen. The genus name Adolfus commemorates the German herpetologist Adolf B. R. F. K. (full name not confirmed).
Characteristics
| Feature | Description |
|---|---|
| Size | Adult snout‑vent length (SVL) typically ranges from 45 mm to 70 mm; total length including tail can exceed 150 mm. |
| Morphology | slender body, relatively long tail, and well‑developed limbs; dorsal scales are smooth and overlapping. |
| Coloration | Dorsal surface generally brown or olive with darker mottling; ventral surface lighter, often pale gray or whitish. Precise pattern varies among individuals. |
| Habitat | Prefers moist, shaded forest floor and low vegetation in montane regions of Kenya and northern Tanzania. |
| Behavior | Diurnal and primarily terrestrial, though it occasionally climbs low shrubs; known to be quick‑moving when disturbed. |
| Reproduction | Oviparous; clutch size and incubation period have not been definitively documented for this species. |
