Figs 5–6

Differential diagnosis

Synagelides leigongensis sp. nov. can easily be distinguished from all other congeners by: 1) retrolateral tibial apophysis is bifurcated basally (not bifurcated, or bifurcated medially or apically in that of other congeners); 2) epigyne lacks median septum and has a large anterior arcuated rim covering almost half the epigynal length.

Etymology

The species name is derived from the type locality; adjective.

Description

Male (holotype)

Measurements. Total length 3.69. Carapace 1.70 long, 1.19 wide. Abdomen 2.03 long, 1.14 wide. Eye sizes and inter-distances: AME 0.37, ALE 0.19, PLE 0.18, AREW 1.19, PERW 1.22, EFL 0.95. Legs: I 4.76 (1.46, 2.39, 0.54, 0.37), II 3.05 (0.95, 1.10, 0.63, 0.37), III 3.20 (0.95, 1.05, 0.83, 0.37), IV 4.36 (1.22, 1.59, 1.07, 0.48). Carapace ( Fig. 6D ) stippled, yellow-brown, with a pair of irregular dark patches anteriorly. Fovea oval, hollowed. Chelicerae ( Fig. 6G ) yellow, with two promarginal teeth and one retromarginal tooth fissident. Endites, labium, and sternum ( Fig. 6E ) colored as chelicerae. Legs pale yellow to yellow except leg I interspersed with brown. Spination of leg I ( Fig. 6H ): femur v2-2-2; metatarsus v0-1-1. Abdomen ( Fig. 6 D–E) elongated; dorsum brown with lateral white patches anteromedially and two pairs of muscle depressions; venter grey-white, terminally brown, with brown dots. Palp ( Fig. 5 A–F): patella about 1.5 times longer than wide; retrolateral tibial apophysis bifurcated, the ventral ramus transparent and pointed apically, the dorsal ramus bent medially and blunt apically; cymbium with a discal dorsal apophysis; embolus flattened, strongly curved terminally and slightly pointed apically; median apophysis well-developed, sclerotized, terminally with little tubercles.

Female (allotype, TRU-Salticid-0014)

Total length 4.48. Carapace 1.59 long, 1.34 wide. Abdomen 2.41 long, 1.34 wide. Eye sizes and interdistances: AME 0.41, ALE 0.23, PLE 0.22, AREW 1.31, PERW 1.35, EFL 1.04. Legs: I 4.28 (1.30, 2.10, 0.51, 0.37), II 3.15 (0.98, 1.15, 0.63, 0.39), III 3.37 (0.98, 1.15, 0.83, 0.41), IV 4.57 (1.24, 1.73, 1.12, 0.48). Habitus ( Fig. 6F ) similar to that of male except paler. Epigyne ( Fig. 6 A–C) slightly longer than wide, with a large anterior arcuated rim; atrium large, almost occupying half the epigyne; copulatory openings located bilaterally; copulatory ducts short, terminally with short gland ducts; spermathecae inflated, boat-shaped; fertilization ducts extending transversely and slightly curved medially in dorsal view.

Distribution

China (Guizhou) ( Fig. 18 ).

Comments

The pairing of this species and the following ones are mainly based on the fact that both sexes were collected from the same sites and share similar markings. Moreover, the sexual dimorphism between the male and female of S. leigongensis sp. nov. is consistent with sexual dimorphism found in related species.
