TYPE MATERIAL. — Holotype. “ FRENCH GUIANA / STM Mont Saint Marcel de la / Haute-Camopi, 26-IX-2014, (inselberg), / N 2°23’03.00” O 53°00’37.00”, altitude / 635m, Commune de Camopi / Automatic Luminating trap / Soc. Ent. Antilles-Guyane leg.” ♂ (MNHN-EH-23001). Paratypes. Same data as holotype, 3♂ and 1♀ (coll. AFSC).
ETYMOLOGY. — The species is named in honor of Maxine S. Heath for her 80th birthday, mentor and friend who saw potential in me and started me on the cicada journey so many years ago and to whom I will always be grateful.
MEASUREMENTS (MM). — N = 4 ♂ or 1 ♀, mean (range). Length of body: ♂ 22.85 (22.2-23.5), ♀ 23.9; length of fore wing: ♂ 32.13 (31.6-32.9), ♀ 34.95; width of fore wing: ♂ 9.8 (9.3-10.1), ♀ 10.75; length of head: ♂ 3.9 (3.8-4.1), ♀ 4.3; width of head including eyes: ♂ 10.88 (10.6-11.2), ♀ 11.4; width of pronotum including suprahumeral plates: ♂ 10.49 (10.0-11.0), ♀ 11.3; width of mesonotum: ♂ 9.18 (8.9-9.55), ♀ 9.5.
DIAGNOSIS. — The new species has a body length (22-24 mm) less than G. bonaerensis (Berg, 1879), G. chlorogena (Walker, 1850), G. jamesi n. sp. and G. rufapicalis Boulard, 1998 all of which have body lengths greater than 25 mm. Although G. rufapicalis has a slightly larger body size (26 mm), the pronotum being the same color as the mesonotum and the circular light area of the ventral abdomen promptly distinguish it from the new species. The smaller body size (21 mm or less) of G. bicolor (Olivier, 1790) n. comb.; G. cuta (Walker, 1850); 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. distinguish them from the new species. 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 new species can be distinguished promptly from G. bleuzeni Boulard & Martinelli, 2011 which lacks the expanded infuscation at the base of the wings and whose mesothorax is marked only along the parasidal suture with black. The ochraceous ventral surfaces of G. densusa Boulard & Martinelli, 2011 and G. jauffreti Boulard & Martinelli, 1996 promptly distinguish them from the new species.
DISTRIBUTION. — The species is only known from the type series collected in French Guiana.
DESCRIPTION
General coloration
Ground color of head and abdomen black, thorax dark testaceous marked with black.
Head
Head wider than mesonotum, black except green anterior margin of vertex. Short golden pile dorsally at junction of frons and postclypeus, longer and more dense pile posterior to eye. Ocelli and eyes green. Ventral head black. Postclypeus centrally sulcate, black except green transverse ridges and medial transverse grooves 2-7 forming a pair of green spots on apex split by black central sulcus. Anteclypeus black. Long golden pile on lorum, gena, lateral postclypeus and anteclypeus. Mentum tawny, black distally, labium castaneous becoming black distally with black lateral surfaces. Rostrum reaching to posterior coxae. Antennal segments black.
Thorax
Dorsal thorax dark testaceous marked with black. Prothorax with transverse black marks posterior to head and within ambient fissure anterior to pronotal collar, transverse marks expanding across midline, anterior mark extending posteriorly into anterior end of paramedian fissure, anterior paramedian fissure marked in some paratypes. Pronotal collar lighter than disc with black mottling. Mesothorax dark testaceous with black lateral sigillae, submedian sigillae, wing grooves, scutal depressions, and elongate black mark with parallel sides that curve to a point anteriorly between submedian sigillae with a rounded posterior terminus between the anterior arms of cruciform elevation. Metanotum black. Variable amounts of short golden pile on dorsal thoracic segments. Long, dense golden pile on lateral and posterior mesonotum, in wing groove, on posterior metanotum, and between anterior arms of cruciform elevation. Ventral thoracic segments black except greenish lateral anepisternum 2 and lateral episternum 3. Ochraceous spot on anteromedial basisternum 3, extending to middle of posterior margin in one paratype and absent in another. Green variable in paratypes. Thoracic sternites covered with long golden pile.
Wings
Fore wings and hind wings hyaline, slight bronzing on apical cells of fore wing.Venation ochraceous at base becoming black distally, costal margin testaceous, black beyond node. Basal cell black with ochraceous spot at base, black reduced in some paratypes so basal cell almost completely ochraceous, pterostigma extending to about middle of apical cell 1, proximal half of clavus infuscated, basal membrane of fore wing grayish black. Hind wing infuscated proximally, venation black, proximally testaceous in some paratypes, except ochraceous proximal cubitus anterior, cubitus posterior and anal vein 1. Infuscation at base of all hind wing cells. Anal cell 3 and anal cell 2 along anal veins 2 and 3, anal cell 1 along anal vein 2, proximal three quarters of cubital cell 2 along cubitus posterior vein, and basal cubital, radial and medial cells grayish-black.
Legs
Legs castaneous with a black posterior stripe, black along medial coxa, anterior trochanter, tarsi and pretarsal claws. Lateral posterior coxae greenish. Fore femora with black distal annulus, proximal spine castaneous adpressed against femur, secondary spine at approximate right angle with broad base, black, and small black tertiary spine. Distal anterior femora and proximal tibiae ochraceous.Tibial spurs and tibial combs castaneous with black tips.
Operculum
Male operculum black with golden pile, slightly angled at lateral base to auditory capsule, rounded posterolateral margin, posterior margin straight to rounded medial margin, not covering tympanum reaching only about three quarters of the distance to sternite II. Medial margin extending to middle of hind coxa. Meracanthus pointed, black with ochraceous lateral margin. Female operculum similarly shaped and colored, reaching to middle of sternite II.
Abdomen
Abdomen tergites black covered with long golden pile, pile very long on posterolateral portions of tergites 7 and 8. Male sternites I, II, VII and VIII black, sternites III-VI translucent green with transversly elongated tawny spot on midline, dense, long golden pile on posterior margin of sternite II. Female sternites black with short golden pile. Timbal cover black, incomplete exposing timbal dorsally, anterior margin curled posteriorly, arching from dorsal base along timbal cavity to semicircular anterior apex, ventral margin slightly angled ventrally. Timbal white with dark brown markings visible through opening in timbal cover. Male sternites VII and VIII black, sternite VIII notched posteriorly. Female sternite VII with sinuate posterior margin and single medial notch. Female abdominal segment 9 black with large green dorsolateral mark, covered with long golden pile.
