Coryptilus longicervix Kawano & Fusu PQ 2019

3.1 Coryptilus longicervix Kawano & Fusu, 2019 Fig. 7 Coryptilus longicervix Kawano & Fusu in Fusu et al., 2019: 323‒331, figs 32‒55. Material examined. CHINA: 1♀, Qingshuisuo, Fujian Tianbaoyan National Natural Reserve, Sanming City, Fujian Province, 1 September 2020, 700m, Malaise trap, DNA 918 (FAFU). Distribution. China (* Fujian, Taiwan), Japan, South Korea. Remarks. Females of this species can be distinguished by the following character states: 1) the fore wing is reduced, extending to about the middle of the gaster (Fig. 7A,B), and approximately 4.5 times as long as it is wide, whereas in the other two described species the fore wings are not reduced, or if they are, they are about 3 times as long as they are wide; 2) the basal cell of the fore wing is hyaline behind the apical half of the submarginal vein (Fig. 7L), whereas in the other two species the basal cell is hyaline only behind the apical one-quarter of the submarginal vein; and 3) the mesoscutum is dark brown or black with a metallic luster (Fig. 7G), whereas in the other two species the mesoscutum is usually orange to brown and lacks a metallic luster. This species has been found in southern Japan, South Korea, and Taiwan island. This is the first record from mainland China. The specimen from Fujian exhibits slight morphological differences from the specimens described and illustrated by Fusu et al. (2019), with most parts of the head being purple (Fig. 7C–E) rather than green or blue. DNA barcode. This is the first DNA barcode of this species and of the genus Coryptilus.
