Material examined.

Holotype ♀, China, Jiangxi Prov., Ji’an City, Jinggangshan County Level City , Ciping Town , Dajing Village , Dajing Forest Farm , 26°34'12"N, 114°7'19.2"E, 956 m, 27 Aug. 2015, Zhi-wu Chen et al. leg.

Etymology.

The name refers to its similarity to D. strophadatus (Zhu & Wang, 1991).

Diagnosis.

The female of this species is similar to that of D. strophadatus in having the labium-like atrium, the long horn-shaped epigynal teeth and the waved copulatory ducts, but differs by the epigynal teeth separated by 1/2 their length (vs. 1/4 in D. strophadatus ) and the copulatory ducts from sub-anterior part of vulvae extending to median part forming a C-shaped turn (vs. from anterior part of vulvae extending to median part forming a S-shaped turn in D. strophadatus ) (Fig. 5C, D ).

Description.

Habitus as in Fig. 5A, B . Total length 8.4. Carapace 3.74 long, 2.64 wide. Eye sizes and interdistances: AME 0.08; ALE 0.21; PME 0.14; PLE 0.19; AME-AME 0.06; AME-ALE 0.08; PME-PME 0.14; ALE-ALE 0.40; PME-PLE 0.13; PLE-PLE 0.59; ALE-PLE 0.13; AME-PME 0.15; AME-PLE 0.29. MOA: 0.41 long; 0.24 anterior width, 0.30 posterior width. Chelicerae with a large basial tubercle, three promarginal teeth (median largest) and two retromarginal teeth (proximal larger). Leg measurements: I 10.16 (2.72, 1.36, 2.2, 2.75, 1.13); II 8.59 (2.26, 1.05, 1.5, 2.45, 1.33); III 8.18 (2.31, 1, 1.81, 1.89, 1.17); IV 9.32 (2.5, 1.05, 2.28, 2.14, 1.35). Abdomen 4.48 long, 2.08 wide.

Coloration. Carapace yellow-brown, posteriorly with dark, narrow, radial stripes. Chelicerae dark yellow-brown. Endites, labium, and sternum dark yellow-brown. Legs yellow-brown. Abdomen brown, dorsally with six pale chevron stripes on the sub-medial part.

Epigyne (Fig. 5C, D ). Atrium, labium-like, arising from posterior. Epigynal teeth long, horn-like, located at anteromedian of epigynum. Copulatory openings located at sub-posterior part of the atrium, covered by a transverse plate. Copulatory ducts S-shaped, extending from sub-posterior to antero-lateral part of vulva, then back, connecting with anterolateral part of spermathecae. Spermathecae ampullate, separated by less than their lengths. Fertilization duct short, located posteriorly on spermathecae, curved posteriorly.

Male. Unknown.

Comments.

Unfortunately, only one specimen of Draconarius substrophadatus sp. nov. was found, as well as of D. strophadatus . They share the similar characters of long epigynal teeth, the labium-like atrium located posteriorly, and the waved copulatory ducts, and the new species is tentatively placed in the genus Draconarius . Hopefully, finding the males of these two species in the future will reveal their generic placement.

Distribution.

Known only from the type locality in Jiangxi Province, China (Fig. 8 ).
