Lin, Yejie & Li, Shuqiang, 2022, Taxonomic notes on seven species of the family Hersiliidae (Arachnida: Araneae) from China and the Philippines, Zoological Systematics 47 (2), pp. 132-145 : 137-139

Hersilia long sp. nov. ( Figs 1E , 4 , 9 )

Type material. Holotype ♀ (IZCAS-Ar42717), China, Sichuan, Garzê Tibetan Autonomous Prefecture, Danba County, Waba Village , 30.9308°N, 101.7646°E, 30.VII.2004, Yi Ming leg.

Diagnosis. The female of the new species resembles those of H. caudata Audouin, 1826 by the narrowed copulatory openings, short copulatory ducts, and slender secondary spermathecae. However, this new species can be distinguished by the diamond-shaped median septum ( Fig. 4A ) (vs. rectangular in H. caudata ( Baehr & Baehr, 1993, fig. 15e)), posterior margin recurved ( Fig. 4B ) (vs. straight in H. caudata ( Baehr & Baehr, 1993, fig. 15f, e)), sickle-shaped fertilization ducts ( Fig. 4B ) (vs. wide, flag-shaped in H. caudata ( Baehr & Baehr, 1993, fig. 15f), and the length of primary spermathecae is the same as the length of the secondary spermathecae ( Fig. 4B ) (vs. primary spermathecae shorter than secondary spermathecae ( Baehr & Baehr, 1993, fig. 31f)).

Description. Female holotype ( Figs 1E , 4A–B ). Total length 7.60. Carapace 2.68 long, 2.74 wide, yellow-brown with brown pattern, margin brown. Clypeus height 0.72, brown anteriorly. Chelicerae brown, terminus dark brown, with 5 retromarginal denticles. Eye area dark brown around PME and PLE; eye sizes and interdistances: AME 0.20, ALE 0.11, PME 0.21, PLE 0.20, AME–AME 0.15, AME–ALE 0.11, PME–PME 0.13, PME–PLE 0.17, AME–PME 0.10, ALE–PLE 0.06. Legs yellow-brown, with black stripe. Leg measurements: leg I: 18.58 (5.19 + 5.96 + 3.99 +2.64 + 0.80), leg II: 18.18 (5.05 + 5.42 + 4.40 + 2.62 + 0.69), leg III: 6.91 (2.09 + 2.16 + 1.82 + 0.84), leg IV: 17.40 (4.67 + 5.23 + 4.17 + 2.46 + 0.87). Leg formula: 1243. Abdomen 4.69 long, 4.22 wide, yellow-brown with black pattern.

Epigyne ( Fig. 4 ) median septum with wrinkles anteriorly; copulatory openings at lateral margins of median septum. Copulatory ducts almost as long as spermathecae in each pair. Two pairs of spermathecae; primary spermathecae ovoid, secondary spermathecae kidney-shaped. Fertilization ducts sickle-shaped.

Etymology. The species is named after the Chinese pinyin long (dragon); noun.

Distribution. Known only from the type locality.
