DistributionN Honduras (Atlantic slopes of the Cordillera Nombre de Dios in the departments of Atlántida and Colón), elevation 0-980 m.

Type locality: Parque Nacional Pico Bonito, Estación Forestal CURLA, 15.70167°N, 86.84667°W, elev. 170 m asl, Departamento de Atlántida, Honduras  
TypesHolotype: SMF 78040, adult male; collected by Gunther Köhler on 23 July 1995; original field number GK-044.
Paratypes: All from Parque Nacional Pico Bonito, Estación Forestal CURLA, 15.70167°N, 86.84667°W, 120–160 m, Departamento Atlántida, Honduras: SMF 78039, 79057–58, collected by Gunther Köhler on 22 July 1995; SMF 78704–07, 81055, collected by Gunther Köhler on 23 March 1996; SMF 78708–09, collected by Gunther Köhler on 27 March 1996; SMF 79943–46, 79948–50, collected by James R. McCranie and Larry David Wilson on 8 June 1996. SMF 78039, 78705–06, 79943–44, 79949 are adult males, the remaining paratypes are adult females. SMF 79057 and 81055 are cleared and stained specimens. 
DiagnosisDiagnosis: A medium-sized (maximum SVL 59.0 mm in males, 53 mm in females) species (our Species C of the Norops tropidonotus complex) of the genus Norops (sensu Nicholson et al., 2012) that is most similar in ex- ternal morphology to N. tropidonotus, N. compressicauda, N. spilorhipis, N. mccraniei, and N. wampuensis. These five species and N. wilsoni are differentiated from all other anoles by a combination of the following characters: (1) distinctly enlarged and strongly keeled dorsal scale rows, (2) a tube-like axillary pocket, (3) scales anterior to ear opening keeled and much larger than small and granular scales posterior to ear opening, and (4) a lack of enlarged postcloacal scales in males. Norops wilsoni differs from the other five species in the Norops tropidonotus com- plex by mean genetic distances of 3.6–4.5%. Norops wilsoni can be distinguished from N. compressicauda by the presence of a large orange male dewlap with a dark central streak (vs. a pink male dewlap in N. compressicauda) and a brownish-red iris color (vs. blue in N. compressicauda). Norops wilsoni differs from N. tropidonotus by the presence of a large, bilobed hemipenis with a large asulcate processus (vs. hemipenis small, unilobate without an asulcate processus in N. tropidonotus). Norops wilsoni differs from N. wampuensis by the presence of a distinct dark streak present in the male dewlap and a slightly larger size reaching 59.0 mm in males, 53 mm in females (vs. distinct dark central streak absent in male dewlap and males and females reaching 51 mm SVL in N. wampuensis). Norops wilsoni differs from N. spilorhipis and from N. mccraniei in having a hemipenis with a single asulcate fin- ger-like processus at the base of the apex (vs. a single asulcate ridge-like processus on the distal part of the truncus in N. spilorhipis and two asulcate processi present, a finger-like one at the base of the apex and a conical one at the base of the truncus in N. mccraniei, respectively). Norops wilsoni differs further from N. mccraniei by its shorter tail (ratio tail length/SVL 1.62–1.78, mean 1.70 in males and 1.44–1.53, mean 1.48, in females of N. wilsoni vs. 1.71–1.85, mean, 1.78 in males and 1.60–1.72, mean, 1.66, in females of N. mccraniei) and fewer scales around midbody (62–78, mean 69.4 in N. wilsoni vs. 70–94, mean 76.9, in N. mccraniei), as well as in the mean values of several additional morphometric and scalation characters (see Table 2, Fig. 3). Also, Norops wilsoni differs further from N. mccraniei in male dewlap coloration (orange with a large diffuse dark central area in N. wilsoni vs. orange with a central dark streak in N. mccraniei). Norops wilsoni differs from the somewhat similar Central American spe- cies N. humilis, N. marsupialis, N. quaggulus, and N. uniformis by the presence of keeled scales anterior to the ear opening, much larger than small and granular scales posterior to ear opening, and a larger size, reaching 59.0 mm in males, 53 mm in females (vs. scales anterior and posterior to ear opening subequal, small, and granular, SVL of adults < 51 mm in N. humilis, < 49 mm in N. marsupialis, < 42 mm in N. quaggulus, and < 42 mm in N. uniformis, respectively).

Species group: Norops tropidonotus complex (with N. compressicauda, N. tropidonotus, N. wampuensis, N. mccraniei, N. wilsoni, N. spilorhipis) fide Köhler et al. 2016. 
Etymology“The specific name wilsoni honors our friend and colleague Larry David Wilson, who is one of the leading authorities of the Honduran herpetofauna. Since the 1960s, Larry has been working on the taxonomy, zoogeography, and conservation of the amphibians and reptiles of Honduras and has written numerous scientific articles and monographic treatments of its herpetofauna.” [KÖHLER et al. 2016].
