Dahira farintaenia ( Zhu & Wang, 1997) [KIJǙƑẶ]

Rhodosoma farintaenia Zhu & Wang, 1997 ; Fauna Sinica ( Insecta ) 11: 318; TL: “Ciping, Jiangxi ” [E. China].

Material examined. CHINA: 2♁♁, 1♀, Shaanxi, Hanzhong , Chenggu County, 1100m, 7.V.2021, Yu-Fei Li leg. ( JZHC, XZBC) ; 1♀, Chongqing, Simian Shan , 1100m, 25.IV.2019, Chao Zhang leg. ( XZBC) ; 1♀, Sichuan, Ya’an , Xingjing County, 1500 m, 10.V.2022, Local collector leg. ( JZHC) .

Description. Male ( Fig. 6A–B ): FWL: 28–30 mm. Upperside: head and thorax greenish; antennae filiform, brownish yellow, apically hooked. Labial palpus protruding, greyish brown. Abdomen terminating with a green tuft. FW elongate, with a falcate apex outer margin slightly excavated below apex but then convex to tornus; ground colour dark olive green, with narrow diffuse pale purple-grey band running from costa towards middle of outer margin; apex with pale yellow spot between veins Rs 2 and Rs 4. HW blackish brown, apical area pale grey. Underside: thorax and abdomen yellowish-white with white legs. FW brown with orange pattern and stripes, outer margin grey. HW light orange with brown stripe towards the middle area, outer margin grey.

Female ( Fig. 6C–D ): FWL: 32–33 mm. Similar to male, with broader wings and green colour on FW darker, purple-grey band much wider.

Male genitalia ( Fig. 7 ): Uncus and gnathos form a typical macroglossine “bird-beak” structure. Uncus thin and slightly curved, with tiny apical hook, sparsely hairy dorsally. Gnathos slightly thicker than uncus, apex blunt. Valva rounded, with basal part wider than terminal part, apex slightly blunt. Sacculus slightly constricted and slightly curved upward apically into harpe. Phallus long and straight, with transverse process distally; anterior lobe of process longer, ending into slender transverse hook with apical spinules on two sides.

Female genitalia ( Fig. 8 ): Anal papillae apophyses sharp. Lamella antevaginalis sclerotized and narrow; lamella postvaginalis blunt; ostial lobe elongate and narrowed. Antrum strongly sclerotized, tubular and curved slightly obliquely. Ductus bursae tubular and membranous, narrower than antrum. Corpus bursae round, signum a leaf-like ovoid sclerotized patch, with tiny spines on both sides.

Distribution. China (Shaanxi, Anhui, Hubei, Sichuan, Chongqing, Jiangxi, Hunan, Fujian, Guangdong, Guangxi).

Biological notes. In this study, this species was collected in evergreen broad-leaf forest in Shaanxi, Chongqing and Sichuan, resting on leaves ( Fig. 9 ) or attracted by lights at night.
