Lee, Young June, 2016, Description of a new genus, Galgoria gen. nov. (Hemiptera: Cicadidae: Cicadinae: Leptopsaltriini: Leptopsaltriina), Zootaxa 4109 (4), pp. 496-500 : 497

Galgoria gen. nov.

Type species. Tanna herzbergi Schmidt, 1932 , monotypic.

Etymology. The generic name is a feminine noun borrowed from the Korean galgori, meaning “a hook” or “a hook-shaped thing” in reference to the hooked uncus in lateral view of the type species, which is quite different from that of Tanna .

Description. Body medium-sized (27–40 mm long in males). Head including compound eyes (holotype 8.9 mm wide) narrower than mesonotum (holotype 9.5 mm wide). Inner area of pronotum with black fasciae along paramedian and lateral fissures. Lateral pronotal collar not dentate. Wings hyaline, with marginal areas very narrow and with infuscated apical margins. Fore wing with very short apical cells, with ulnar cell 3 more than three times as long as apical cell 5, except for apical cell 1 which is very long and slender, longer than 7.5 times the width; ulnar cell 3 with very long basal side (contacting side with radial cell), longer than 1.5 times (usually longer than twice) as long as basal side of medial cell. Fore wing with infuscations on radial and radiomedial crossveins and on apical cell 1 but not on its hind margin. Male operculum small, semicircular, broader than long, not extending beyond posterior margin of abdominal sternite II. Male abdomen obconical, about as long as or slightly longer than head and thorax together. Male abdominal tergite 3 slightly wider than mesonotum. Timbal cover about as wide as long, mostly concealing timbal in dorsal view. Male abdominal sternites III and IV with tubercle-like projection on each lateral surface. Male pygofer oblong in ventral view. Uncus not bifurcate but incised medially at apex in ventral view; long and slender but widened apically in ventral and lateral views; curved inwardly in lateral view. Basal lobe of pygofer absent. Aedeagus thin apically, protruding out of cover-like process hidden under uncus. Ovipositor very long, protruding far beyond abdominal segment 9.

Remarks. This genus has a body shape and fore wing venation similar to those of Tanna with the following common characters: head including compound eyes narrower than mesonotum; fore wing with very short apical cells (except for apical cell 1 in the new genus), with ulnar cell 3 more than 2.40 times as long as apical cell 5. However, this genus is distinguished from Tanna by the following characters: inner area of pronotum nearly concolorous with pronotal collar [completely different-colored from pronotal collar in Tanna ] and with black fasciae along paramedian and lateral fissures [no such marks in Tanna ]; fore wing with infuscation on apical cell 1 [without infuscation on apical cell 1 in Tanna ] as well as on crossveins; fore wing apical cell 1 very long and slender, longer than 7.5 times the width [shorter than 7.0 times the width in Tanna ]; fore wing ulnar cell 3 with very long basal side, longer than 1.5 times as long as basal side of medial cell [about as long as basal side of medial cell in Tanna ]; fore wing without infuscations [with a series of roundish infuscations in Tanna ] along its hind margin; hind wing with infuscated apical margin [not so in Tanna ]; male abdomen obconical, about as long as or slightly longer than [distinctly longer than in Tanna ] head and thorax together; male abdominal tergite 3 slightly wider [much wider in Tanna ] than mesonotum; uncus very long and slender [short in Tanna ]; aedeagus thin apically [very thick and truncated apically in Tanna ]; and ovipositor very long, protruding far beyond abdominal segment 9 [very slightly protruding beyond abdominal segment 9 in Tanna ].
