Etymology. The specific name is a combination of the Latin “ furcae- ” (fork) and “- oideo ” (seem), referring to the bottom of the palpal bulb being fork-shaped and similar to S. furcatus ; adjective.

Diagnosis. The new species resembles S. hortonensis ( Kanesharatnam & Benjamin, 2020, figs 1A–G, 2A–E, 3A–E) in having slender and weak embolus, strong retrolateral tibial apophysis, and obvious intermediate tibial apophysis ( Kanesharatnam & Benjamin 2020, figs 1D–G, 2A–C), but can be distinguished by: (1) the presence of terminal apophysis, the bulb with two proximal lobes, and the tibia with four apophyses ( Figs 1–3 View FIGURES 1–3 , 11–12 View FIGURES 11–14 ), while the terminal apophysis is absent, the bulb has one proximal lobe, and the tibia has two apophyses in S. hortonensis ( Kanesharatnam & Benjamin 2020, figs 1D–G, 2A–C); (2) the embolus slender in ventral view ( Figs 2 View FIGURES 1–3 , 11 View FIGURES 11–14 ), while the embolus is broad at the spiral base in S. hortonensis ( Kanesharatnam & Benjamin 2020, figs 1D–E, 2B); (3) the copulatory openings located on the posterior margin of epigynum in ventral view ( Figs 4–5 View FIGURES 4–10 , 13 View FIGURES 11–14 ), while the copulatory openings are located on the median area of epigynum in S. hortonensis ( Kanesharatnam & Benjamin 2020, figs 2D, 3D); (4) the copulatory ducts long and narrow with thin wall ( Figs 6 View FIGURES 4–10 , 14 View FIGURES 11–14 ), while the copulatory ducts are short and stout with thick wall in S. hortonensis ( Kanesharatnam & Benjamin 2020, figs 2E, 3E).

Spinnerets yellow.

Palp ( Figs 1–3 View FIGURES 1–3 , 11–12 View FIGURES 11–14 ). Crack of palpal bulb extending to lateral edge; distal lobe strong, with a bifurcate tip; bulb with two proximal lobes and the lower one longer; length of retrolateral tibial apophysis 1.5 times as its width; intermediate tibial apophysis wide and short, approximately trapezoidal, with blunt end; ventral tibial apophysis strong, and slightly longer than intermediate tibial apophysis; distal tibial apophysis three times longer than wide; postero-retrolateral cymbial apophysis short, subequal to 1/5 of the length of cymbium; embolus slender, accompanied by membrane; terminal apophysis wide and centrally concaved.

Female ( paratype, HUN-CGY24). Total length 4.42. Carapace 1.72 long, 1.21 wide. Abdomen 2.48 long, 1.59 wide. Clypeus height 0.08. Eye diameters and interdistances: AME 0.39, ALE 0.21, PLE 0.20, AER 0.99, PER 1.06, EFL 0.94. Leg measurements: I 3.19 (1.06, 1.46, 0.38, 0.29), II 2.37 (0.78, 0.87, 0.41, 0.31), III 2.54 (0.71, 0.84, 0.68, 0.31), IV 3.72 (0.99, 1.48, 0.91, 0.34). Leg formula: IV–I–III–II. All of the body, markings, and other morphological features same as in male.

Epigynum ( Figs 4–6 View FIGURES 4–10 , 13–14 View FIGURES 11–14 ). The length of the epigynum about 3/4 of its width; the epigynal hoods located central-posteriorly; two fossae small, occupying 1/13 of the epigynal plate, with distinctly arcuated rims; copulatory openings located posteriorly; the width of the median septum about 1/5 of the epigynal width; copulatory ducts long and hook-shaped, ascending obliquely and then extending transverse, near terminally with short bar-shaped gland ducts; spermathecae with two chambers, anterior chamber of spermathecae pear-shaped, posterior chamber of spermathecae kidney-shaped; junction duct of spermathecae long and narrow.
