Type locality: UGANDA, Western Region, Kigezi sub-region, Kabale District, Bwindi Impenetrable National Park, near Ruhija village, 01°2′54.096′′S 29°46′36.624′′E, 2284 m elevation  
TypesHolotype: UTEP 21490 (field no. ELI 2755), adult female, 26 May 2014, collected at night from natural vegetation along a roadside near Institute for Tropical Forest Conservation (ITFC) by C. Kusamba, M.M. Aristote and W.M. Muninga (Fig. 8E).
Paratopotypes: Same collection details as holotype, two adult females, UTEP 21486 (field no. ELI 2754) and UTEP 21487 [field no. ELI 2788 (28 May 2014)], col- lected at night from forest edges c. 3 m above ground along a road to ITFC, and one adult male, UTEP 21488 (field no. ELI 2756), collected at night with aid of stick from c. 5 m above ground in sleeping perch of tree behind ITFC (main office) by D.F. Hughes, K.A. Tolley, S. Davies and A.A. Turner.
Paratype: One adult male, UTEP 21489 (field no. ELI 2827), UGANDA, Western Region, Rwenzururu sub-region, Kasese District, near Rwenzori Mountains National Park, Ruboni village, 00°20′58.992′′N 30°1′47.028′′E, 1655 m elevation, 31 May 2014, col- lected at dusk from c. 3 m above ground in sleep- ing perch of vegetation (secondary forest) in front of the Ruboni Community Hotel by D.F. Hughes, E. Greenbaum and M. Behangana. 
DiagnosisDiagnosis: Kinyongia tolleyae sp. nov. can be distinguished from all other Kinyongia species by the fol- lowing combination of traits: (1) lack of rostro-nasal ornamentation in both sexes; (2) moderate body size (mean SVL = 56.6 mm); (3) anterior dorsal keel with 5–10 conical tubercles; (4) casque slightly elevated above the nape; (5) two smooth, expanded areas pre- sent on the casque that appear bilobed when viewed from above; (6) absence of both a gular and ventral crest; (7) 13–17 upper and 14–16 lower labials; (8) tail length longer than SVL in both sexes; (9) parietal crest with several slightly raised tubercles that fork towards the snout; (10) background coloration of the body in adult females is generally light green to yellow-green; background coloration of the body in adult males is generally light brown with anteriorly positioned green patches and peach speckling near the head; (11) large dark brown patches with white centres are present on the lateral flanks of adult females and these lateral patches are typically oriented with a larger patch positioned anteriorly and sometimes a second smaller patch positioned posteriorly from mid-body; (12) areas of darker brown pigment cover the cloacal region and extend distally onto hidden parts of the hind limbs and tail in adult females; (13) interstitial skin between the tubercles on the body is generally white and sometimes green for both sexes; (14) a brown stripe passes through the middle of the eye and extends from the canthal ridge to the temporal crest, and the eye skin above and below the stripe is powder blue/teal, gradually dissipating dorsally and ventrally; (15) the top of the head is somewhat darker green than elsewhere; (16) gular region and ventral portions of the body are distinctly off-white.

Differential diagnosis: A medium-sized forest chameleon that is distinguished from most other conge- ners by the absence of a rostral process in both sexes (K. asheorum, K. boehmei, K. carpenteri, K. fischeri, K. magomberae, K. matschiei, K. msuyae, K. multitu- berculata, K. oxyrhina, K. tavetana, K. tenuis, K. uluguruensis, K. uthmoelleri, K. vanheygeni, K. vosseleri and K. xenorhina). The new species can be distinguished from K. adolfifriderici by its larger snout length and more upper (13–17 vs. 10–14) and lower (14–16 vs. 12–15) labials. The new species can be distinguished from K. rugegensis sp. nov. by the presence of two dis- tinctly expanded and smooth portions of the upper casque (bilobed appearance), slightly smaller head width, fewer upper labials (13–17 vs. 16–18), and smaller fleshy papillae medial to rotulae on hemipenis. The new species can be distinguished from K. itombwensis sp. nov. by its larger snout length, slightly larger forelimbs and casque–eye distance and generally more conical tubercles on the dorsal crest (5–10 vs. 6–7). The new species can be distinguished from K. mulyai and K. excubitor by the presence of a dorsal crest with 5–10 conical tubercles and marked mitochondrial sequence divergence. The new species can be distinguished from K. gyrolepis by a smaller mean body size (56.6 mm vs. 67.3 mm) and current distribution in moist Afromontane rainforest.

EtymologyThe specific epithet is named in honour of Krystal A. Tolley for her substantial contributions to chameleon biology, with the Latin suffix –ae to denote feminine genitive singular. To date, Krystal has participated in the description of 12 new chameleon species, published copious primary research articles on chameleons covering a remarkable breadth of subjects and coauthored (or edited) two important books on chameleons (Tolley & Burger, 2007; Tolley & Herrel, 2013).
