Trioceros harennae, also known commonly as the Harenna hornless chameleon, is a species of lizard in the family Chamaeleonidae. The species is endemic to Ethiopia.[2] There are two recognized subspecies.

Etymology

The specific name, harennae, refers to the Harenna escarpment in the Bale Mountains of Ethiopia. The subspecific name, fitchi, is in honor of Free Methodist minister Stephen Fitch who was one of the collectors of the holotype.[2][3]

Geographic range

T. harennae is native to the Bale Mountains in the regional state of Oromia in Ethiopia.[1][2]

Habitat

The preferred natural habitats of T. harennae are forest and shrubland (above treeline), at altitudes of 2,400–3,300 m (7,900–10,800 ft).[1]

Description

T. harennae may attain a total length (including tail) of 13.8 cm (5.4 in).[1]

Reproduction

The mode of reproduction of T. harennae has been described as viviparous[1] and as ovoviviparous.[2] Litter size is 8–12.[1]

Subspecies

Two subspecies are recognized as being valid, including the nominotypical subspecies.[2]

• Trioceros harenae harennae (Largen, 1995)
• Trioceros harennae fitchi (Nečas, 2004)

Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Trioceros.
