Head (Figs. 1 – 2). Symmetrical and elongate; dorsal surface moderately shiny and sparsely punctated; interocular width equals 5.3 transverse eye diameters; median side depression. Clypeus with anterior margin deeply depressed at middle, with sparser punctures evenly distributed; apex slightly reflexed dorsally. Frons laterally with punctures coarser and slightly denser than those on clypeus, medially with sparser punctures but similar in size to those on clypeus. Eyes large, laterally protruding, partially covered by an elongate eye-canthus extending laterad. Antennal club approximately as long as the footstalk. Pronotum (Fig. 1). Trapezoidal, approximately as long as wide, moderately convex dorsally, with gently curved lateral margins with posterior margin weakly and roundly emarginate at middle; surface entirely glabrous. Punctation composed of a mixture of coarse and fine punctures, becoming sparser and finer on posteromedial area. A distinct longitudinal white macula is present along each lateral declivity, with an additional pair of small inner white spots medially. Scutellum (Fig. 1). Triangular with length 1.2 times as long as width, elongate, nearly flat; surface moderately shiny, smooth, without punctures, entirely glabrous. Elytra (Fig. 1). Somewhat elongate, with a broad base, largely glabrous but distally with some short setae on declivity. Two distinct costae on each elytron extending from middle to the distal declivity, meeting each other at distal end. Punctures on outer areas large and moderately dense, occasionally contiguous and forming C- or Ushaped impressions; punctures on inner areas somewhat large and sparser, notably sparse around scutellum. Pygidium (Fig. 4). Broad, pentagonal; surface flat, coarsely and densely, rugose in part. Venter (Figs. 2 – 3). Prosternum broad, densely rugose. Mesosternum broad densely with punctures sometimes contiguous and forming wavy or C-shaped impressions; mesosternal process developed and broadly rounded. Abdomen with 2 – 3 transverse rows of C-shaped punctures on each ventrite; ventrite 6 noticeably short and compressed, protruded ventrally. Legs (Figs. 1 – 2, 7). Femora densely covered with long setae. Protibiae apically with two distinct outer teeth, with one rudimentary outer tooth at middle; posterior surface with three longitudinal grooves, apically with one well-developed spur. Meso- and metatibiae each equipped with two well-developed apical spurs. Length ratios of tarsomeres I – V approximately 1.0: 1.7: 1.6: 1.6: 2.0; tarsomere I short, tarsomeres II – V elongate; claws slender and simple. Aedeagus (Figs. 5 – 6). Parameres elongate and symmetrical; sub-apices without any distinct swelling; apices curved outward. Each paramere with outer margins shallowly depressed at just after middle. Sexual dimorphism (Figs. 8 – 11). Females differ from males as follows: third outer tooth of protibia well-developed; abdominal ventrite 6 not protruded ventrally. Variability (Figs. 1 – 11). Body length measured from anterior margin of clypeus to elytral apex 11.96 – 15.53 mm, maximum width measured around humeri 6.07 – 8.10 mm (n = 20, including both sexes). The body color ranges from green to deep green, pale reddish green and shiny. Maculae ranges from white to light yellowish brown, occasionally with a small macula on scutellum; One or two small maculae sometimes present at base of elytron, sometimes absent in some individuals; one or two pairs of maculae sometimes occurring on abdominal ventrites 1 to 5, but sometimes absent in some specimens. Dorsal surface of elytra either glabrous or bears sparse setae in some individuals.	en	Seshima, Yûhi, Yoshida, Takahiro (2025): Taxonomic study of the flower chafer genus Gametis Burmeister, 1842 (Coleoptera: Scarabaeidae: Cetoniinae) in Japan, with a description of a new species from Tarama-jima Island and Minna-jima Island, the Miyako Islands, southwestern Japan.

The three subspecies were described on the same paper by Nomura (1959). Among them, G. f. ishigakiana is the most widely distributed and common. Following recommendation 24 A of the International Code of Zoological Nomenclature (ICZN 1999), G. f. ishigakiana is selected here as the nominotypical subspecies under the First Reviser Rule.	en	Seshima, Yûhi, Yoshida, Takahiro (2025): Taxonomic study of the flower chafer genus Gametis Burmeister, 1842 (Coleoptera: Scarabaeidae: Cetoniinae) in Japan, with a description of a new species from Tarama-jima Island and Minna-jima Island, the Miyako Islands, southwestern Japan.
