Gao, Qiang & Wang, Shuxia, 2018, Seven new species of the genus Circobotys Butler from China (Lepidoptera: Crambidae), with a checklist of the world, Zoological Systematics 43 (2), pp. 196-210 : 197-198

Genus Circobotys Butler, 1879

Circobotys Butler, 1879: 77 . Type species: Circobotys nycterina Butler, 1879 , by original designation.

Circobotis Mutuura, 1954: 14. (misspelling).

Generic characters. Frons slightly rounded and convex. Labial palpus porrect, exceeding frons by about 1.5 times as long as length of head, third segment slightly drooping. Maxillary palpus developed, slightly dilated with scales distally. Forewing with costal margin somewhat straight, apex sharp or obtuse, termen roundly oblique or straightly truncate, tornus obtuse; cell about half length of wing, R 1 from 4/5 of anterior margin, R 3 and R 4 stalked about 2/3 distance from upper corner to apex, M 1 from about middle, M 2 and M 3 from posterior angle, CuA 1 from before posterior angle, CuA 2 from 2/3 of posterior margin. Hindwing with cell about 1/3 length of wing; Sc+R 1 and Rs anastomosed for half-length of Rs; M 2, M 3 and CuA 1 from posterior angle, approximated at base; CuA 2 from 3/4 of posterior margin ( Fig. 1 ).

Male genitalia ( Fig. 2 ). Uncus mostly sub-triangular, setose, pointed apically. Transtilla short or elongate triangular; valva broad, or narrowly elongate; sella and editum present or absent; sacculus usually with a thumb-shaped or triangular dorsal process. Phallus cylindrical; cornutus present or absent, often spine-like if present.

Female genitalia ( Fig. 3 ). Papillae anales densely setose. Apophyses slender. Antrum short. Ductus bursae with long sclerite posteriorly. Corpus bursae oval, with appendix bursae; sigum mostly rhomboid.

Distribution. China (Anhui, Beijing, Chongqing, Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hebei, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Liaoning, Ningxia, Shaanxi, Shandong, Shanxi, Sichuan, Taiwan, Tianjin, Yunnan, Zhejiang) ( Fig. 4 ), Korea, Japan, Russia (Siberia and Far East), India, Burma, Malaysia and Australia.

Remarks. Circobotys is relatively rich in China. Of the 20 described species in the world, 11 species were recorded to occur in China. In this study, we identified eight known Chinese species on the examination of the available specimens in our collection. However, we are unable to get the specimens of C. arrogantalis ( Tams, 1927) , C. elongata Munroe & Mutuura, 1969 and C. plebeia Munroe & Mutuura, 1969 . The species lacking specimens for investigation or with untraceable types are distinguished based on the original descriptions when establishing new taxa.
