description: Barsine qinxiae S.-Y. Huang & Volynkin, sp. n.
(Figs 1–2, 17, 18)
Type material. Holotype (Figs 1, 17): male, 11.VII.2017, Yujikeng, Jingning She Autonomous County, Lishui City, Zhejiang Province, China, Jing-kun Zhang leg., by light trap, gen. prep. No.: LHSY013 (Coll. SCAU). Paratype: male, 15. VI.2021, Dayuse Village, Quzhou City, Zhejiang Province, China, Zhuo-yin Jiang leg., gen. prep. No.: LHSY175 (Coll. CHSY).
Diagnosis. Externally, B. qinxiae sp. n. is unique amongst the genus Barsine due to the bicolored forewing with a scarlet ground color and a large black central patch. Since the female of B. qinxiae sp. n. and the males of B. hoenei and B. jingkuni sp. n. are unknown, the copulatory organ of the new species is compared only to B. pardalis (Figs 9, 10, 19, 23, 24) and B. roseata (Figs 11–16, 20, 27), from which it is distinguished by the combination of the following characters. (1) The uncus is shorter. (2) The membranous lobe of the valva is similar to B. pardalis but shorter and narrower than in B. roseata. (3) The basal saccular process is thick and short while it is long and slender in B. roseata and B. pardalis. (4) The dorsal lobe of the distal saccular process is long and thumb-like while it is vestigial in B. roseata and short and dent-like in B. pardalis. (5) The phallus is much longer and slender than in the congeners. (6) The 1 st medial diverticulum of the vesica is markedly smaller, shorter and narrower. (7) The 2 nd medial diverticulum is conspicuously smaller, narrower and scattered with larger cornuti.
Description. Male (Figs 1–2). Forewing length 15.5–17.2 mm (n=2, 17. 2 mm in holotype). Antenna weakly ciliate. Head and thorax covered with scarlet hair-like scales. Abdomen covered with hair-like scales, black dorsally and scarlet ventrally. Forewing ground color scarlet with large black oval central patch. An additional black lengthwise stripe present at dorsum. Cilia scarlet. Hindwing ground color black. Cilia black above anal angle and reddish at anal angle.
Female unknown.
Genitalia. Male (Figs 17, 18). Uncus short and curved subapically. Tegumen triangular, relatively short and broad. Juxta broad, X-shaped. Saccus broad, U-shaped. Valva lobular. Costa heavily sclerotized, medial costal process broadly triangular. Membranous lobe of valva narrow and short. Sacculus heavily sclerotized, with thick and stout basal process. Distal lobe of distal saccular process long and narrow, distally somewhat tapered and apically rounded. Dorsal lobe of distal saccular process slightly shorter than distal one, gradually tapered distally and gently curved medially. Phallus slender, tubular and almost straight. Vesica broad with short basal diverticulum. 1 st medial diverticulum of vesica long and broad, with granulation field distally. 2 nd medial diverticulum short, covered with numerous cornuti of different sizes from base to subapical section. 3 rd medial diverticulum broad basally and abruptly narrowed towards distal end, covered with large cornuti basally and granulation field in the elongated part. 4 th medial diverticulum vestigial. 5 th medial diverticulum globular, covered with numerous cornuti of various sizes. Basal plate of vesica ejaculatorius long and broad, triangular.
Distribution. Currently only known from Zhejiang Province in Eastern China.
Etymology. The species is named after Ms. Qin-xi Xie, the beloved of the collector of the holotype, Mr. Jingkun Zhang.
