Description.

Male holotype (Fig. 24A, C, E, G, I ). Total length 4.33; carapace 2.18 long, 1.64 wide, opisthosoma 2.04 long, 1.36 wide. Eye sizes and interdistances: AME 0.07, ALE 0.10, PME 0.08, PLE 0.09, AME-AME 0.07, AME-ALE 0.02, PME-PME 0.08, PME-PLE 0.06, AME-PME 0.10, ALE-PLE 0.04. Anterior eye row recurved, posterior eye row straight. Chelicerae with four promarginal and four retromarginal teeth. Legs with long brown hair. Leg measurements: I 5.84 (1.66, 2.09, 1.22, 0.87), II 4.62 (1.34, 1.63, 0.93, 0.72), III 3.87 (1.11, 1.21, 0.93, 0.62), IV 6.47 (1.71, 2.22, 1.69, 0.85). Opisthosoma oval, venter brown with setae, dorsal scutum almost 1/3 the length of the opisthosoma. Spinnerets yellow brown.

Palp (Figs 21A-C , 22A, B ). Femur almost 5 × longer than patella, curved, tip with spines. Tibia almost 0.7 of patella length. Retrolateral tibial apophysis (RTA) almost 1.5 × wider than long, tip with kind of hood (H). Cymbium almost 1.5 × longer than wide, with retro-proximal cymbial outgrowing. Subtegulum (ST) large, almost 0.5 length of the cymbial length (prolateral view). Tegulum small. Tegular apophysis (TA) with wide base, ~ 2/3 of its length, tip claw-like. Conductor (C) absent. Embolus (E) complex, almost triangle shaped, as wide as bulb. Embolus proper (EP) straight, directed anteriorly, with large retrolateral lamina with six spine-like apophyses: one anterior (EA2), one dorsal (EA1), two retrolateral (EA3, 4) and two posteriors (EA5, 6).

Female paratype (IZCAS-Ar44488) (Fig. 24B, D, F, H, J ). Total length 4.07; carapace 1.68 long, 1.28 wide, opisthosoma 2.48 long, 1.53 wide. Eye sizes and interdistances: AME 0.13, ALE 0.12, PME 0.12, PLE 0.11, AME-AME 0.02, AME-ALE 0.01, PME-PME 0.04, PME-PLE 0.02, AME-PME 0.06, ALE-PLE 0.02. Anterior eye row almost straight, posterior eye row recurved. Chelicerae with four promarginal and two retromarginal teeth. Leg measurements: I 4.27 (1.24, 1.54, 0.83, 0.66), II 3.55 (1.08, 1.21, 0.70, 0.56), III 3.32 (1.00, 1.21, 0.70, 0.56), IV 4.68 (1.23, 1.58, 1.21, 0.66). Opisthosoma oval, without dorsal scutum, venter yellow-brown with long brown setae. Spinnerets pale yellow.

Epigyne (Fig. 23A, B ). Epigynal plate 1.5 × longer than wide, with short scape (SC) located anteriorly. Copulatory openings (CO) located anteriorly, slit-like, slightly arched, each 0.5 of plate width. Copulatory duct (CD) wide, laminar (0.5 of plate width), with anterior incision (CDi). Spermathecae (S) small, subglobular, slightly wider than long, separated by ~ 1/5 of their width, located posteriorly. Fertilization ducts directed at 2 o’clock position from spermathecae.

Distribution.

Known only from the type locality.

Etymology.

The species is named after Lu Junyi, one of the 108 outlaws in the classical Chinese novel 'Outlaws of the Marsh’; noun in apposition.
