Etymology. The specific epithet is derived from the Latin noun “puteus ” meaning “pit” and referring to cephalic region with lateral pits behind the posterior eye in male.

Diagnosis. Sinogone puteus sp. n. resembles S. caesum in having the similar morphology of male palp ( Figs 226A–D View FIGURE 226 ; Irfan et al. 2023, figs 21A–D), and can be differentiated by the anterior radical process somewhat rectangular in S. puteus sp. n. ( Fig. 226A View FIGURE 226 ; vs. comma-shaped).

Description. Male (holotype, Figs 227A–C View FIGURE 227 ): Total length: 2.44. Carapace 1.19 long, 0.99 wide, cephalic region strongly elevated with pits present behind the PLEs, yellow, fovea, cervical and radial grooves distinct. Clypeus 0.35 high. Chelicerae with three promarginal and four retromarginal teeth. Sternum shield-like, yellow with microsetae. Eyes: AER recurved, PER straight, slightly wider than AER. Eye sizes and interdistances: AME 0.06, ALE 0.07, PME 0.04, PLE 0.06, AME–AME 0.02, PME– PME 0.07, AME–ALE, 0.06, PME–PLE 0.09, AME– PME 0.07, ALE–ALE 0.35, PLE–PLE 0.38, ALE–PLE 0.01. Length of legs: I 4.41 (1.27, 1.57, 1.11, 0.46), II 4.19 (1.24, 1.46, 1.05, 0.44), III 3.31 (1.01, 1.04, 0.86, 0.40), IV 4.16 (1.21, 1.36, 1.15, 0.44). Tibial spine formula: 2- 2-1-1. TmI 0.36 and TmIV present. Opisthosoma 1.46 long, 1.03 wide, oval, brown, mid dorsally with two pairs sigillae, ventral side brown.

Palp ( Figs 226A–D View FIGURE 226 ): Femur unmodified, almost longer than patella and tibia. Patella three times longer than basal part of tibia. Tibia two and half times the length of cymbium, with one reterolateral and one dorsal trichobothria, dorsal tibial apophysis (DTA) distal end bifurcated tip; cymbium elongate, unmodified; paracymbium (PC) sclerotized, U-shaped, distal arm long, slightly overlapping the cymbium; tegulum (T) with small transparent protegulum (PT). Radix (R) robust, sclerotized give rise to long curved embolus; radix wider than long; median membrane (MM) with broad frayed end; anterior radical apophysis (ARP) almost rectangular in prolateral view; embolus (E) long, sclerotized, arc-shaped, overlapping the apex of cymbium.

Female. Unknown.

Distribution. Known only from the type locality (Hubei Province, Fig. 314 View FIGURE314 ).
