Common NamesE: Aberdare Mountains Dwarf Chameleon 
Trioceros kinangopensis — SPAWLS et al. 2018: 295 
DistributionKenya (Aberdare mountains), 3500–3600m elevation

Type locality: Kinangop Peak (3500m), Aberdare Mountains National Park, Kenya.  
Reproductionviviparous (phylogenetic imputation, fide Zimin et al. 2022) 
TypesHolotype: NMK 3071/12, adult male, collected by Jan Stipala and Joash Nyamache on 24th February 2007. Paratypes. 7 males and 5 females. NMK 3071/1, 3–5, 7, 11, males, NMK 3071/ 2, 6, 8–9, females, locality same as holotype; NMK 2536/1, male, NMK 2536/2, female, vicinity of Kinangop Peak. 
DiagnosisDiagnosis: A small, robust-bodied chameleon that differs from other members of the bitaeniatus group in having a combination of the following characters: tail shorter than SVL in both sexes; heterogeneous body scalation (fine body scales with small scattered tubercles and two lateral rows of enlarged tubercles on each flank); low straight casque; short gular crest (orange in males); scales on the temporal region moderately enlarged and graduating in size posteriorly to merge with the body scales; snout with sloping profile and smooth canthus rostrales [STIPALA et al. 2012]. 
CommentSimilar species: T. schubotzi but T. kinangopensis differs in the lack of sexual size dimorphism, smaller-sized females, smoother, less angular canthus rostrales, smaller scales on the temporal region and a bright orange gular crest in males.

Abundance: only known from its original description (Meiri et al. 2017). 
EtymologyT. kinangopensis sp. nov. is named after the collecting locality, Kinangop Peak at the southern end of the Aberdare Mountains, Kenya.
