ETYMOLOGY. — The species is named in honor of James E. Heath for his 80th birthday, mentor and friend who started me on the cicada journey so many years ago and to whom I will always be grateful.
MEASUREMENTS (MM). — N = 3 ♂ or 6 ♀, mean (range). Length of body: ♂ 34.3 (32.2-36.7), ♀ 30.91 (29.2-32.6); length of fore wing: ♂ 47.57 (43.8-50.2), ♀ 45.23 (43.1-46.8); width of fore wing: ♂ 13.97 (12.9-14.7), ♀ 13.38 (12.8-13.7); length of head: ♂ 6.68 (4.55-4.8), ♀ 4.63 (4.4-4.8); width of head including eyes: ♂ 13.7 (13.2-14.3), ♀ 13.6 (13.3-14.3); width of pronotum including suprahumeral plates: ♂ 13.42 (13.0-13.7), ♀ 13.4 (12.8- 14.1); width of mesonotum: ♂ 11.87 (11.6-12.0), ♀ 11.6 (11.1-12.1).
DIAGNOSIS. — The new species has a body length (32-37 mm) greater than G. bicolor (Olivier, 1790) n. comb., G. bleuzeni Boulard & Martinelli, 2011, G. cuta (Walker, 1850), G. densusa Boulard & Martinelli, 2011, G. jauffreti Boulard & Martinelli, 2011, G. maxineae n. sp., G. nadae Gogala, Šporar, Sanborn & Maccagnan, 2015, G. nigra Boulard, 1999, G. parvula (Jacobi, 1904) n. comb., G. platyrhina Sanborn & Heath, 2014 and G. sublaqueata (Uhler, 1903) n. comb. all of which have body lengths less than 25 mm. The smaller body size (26 mm), the infuscated basal area of the fore wing and hind wing and the circular light area of the ventral abdomen promptly distinguish G. rufapicalis Boulard, 1998. The new species can be distinguished simply from G. atalapae Boulard & Martinelli, 2011 by the orange basal area and smoky distal edge of the fore wing of G. atalapae. The closest in body size to G. jamesi n. sp. are G. bonaerensis (Berg, 1879) and G. chlorogena (Walker, 1850). The yellow and green body markings promptly distinguish G. bonaerensis from the almost monochromatic new species. Finally, G. jamesi n. sp. can be distinguished promptly from G. chlorogena by the lack of green in the basal membranes of the wings, the infuscation of the basal area of the wings and the black in the basal cell of the fore wing of the new species.
DISTRIBUTION. — The species is known only from the type series collected in French Guiana.
