sp. nov.

Barsine tongi Huang & Volynkin   , sp. nov.

( Figs 13–16 View FIGURES 11–20 , 27, 28 View FIGURES 25–28 , 36 View FIGURES 33–38 )

Type material. Holotype: male, 10. IV. 2019, parking lot of the main peak of Mt. Jianfengling , 108°52′34.2″E, 18°42′34.9″N, 954m, Hainan Province, P.R. China, leg. Jun-bo Tong (Coll. SCAU) GoogleMaps   . Paratypes: 2 males, 2 females, same data as holotype (Coll. SCAU) GoogleMaps   ; 1 male, 4. IX. 2016, mountain resort in Mt. Jianfengling , Hainan Province, P.R. China, leg. Min Wang & Zhen-fu Huang (Coll. SCAU)   .

Diagnosis. Adults of B. tongi   sp. nov. are very similar externally to those of B. bigamica   , and can only be distinguished from the latter by the examination of genitalia. The male genitalia capsule of B. tongi   is similar to that of B. bigamica   , but can be distinguished by the longer and more robust basal saccular process and more robust medial costal process (whereas in B. bigamica   the basal saccular process is shorter and narrower and the medial costal process is narrower basally). The aedeagus vesica structure of B. tongi   sp. nov. differs from that of B. bigamica   by the 2 nd medial diverticulum directed laterally and covered with more robust cornuti and an additional granulation area (in B. bigamica   the 2 nd medial diverticulum is directed distally and covered with less robust cornuti and bears no granulation area); 3 rd medial diverticulum being more robust thoroughly with its basal section covered with larger cornuti, and the medial cornuti band extending from the base of vesica to the tip of the 2 nd medial diverticulum, U-shaped and the opening of it orients laterally (in B. bigamica   the medial cornuti band extends from the tip of the 2 nd medial diverticulum to the top of the base of the 3 rd medial diverticulum, V-shaped, and the opening of it orients distally). The female genitalia of B. tongi   sp. nov. differ conspicuously from those of B. bigamica   by their much larger corpus bursae, broader sclerotized area of the posterior section of corpus bursae, and larger signum bursae.

Distribution. Currently only known from Mt. Jianfengling, Hainan Province, South China.

Etymology. The species is named after Mr. Jun-bo Tong (SCAU, China) who collected most part of the type series.
