Material examined.

1 ♂ 1 ♀ (TRU - JS 0770–0771), China: • Guangxi Zhuang Autonomous Region, Fangchenggang City, Shiwandashan National Nature Reserve, west border of Pinglong Station (21°50.73'N, 107°53.24'E, ca 430 m), 30. IV. 2024, A. L. He et al. leg .

Diagnosis.

Siler hanoicus resembles that of S. cupreus in the general shape of copulatory organs but differs in: 1) embolus (E) curved (Fig. 25 B) vs straight (Peng 2020: fig. 296 b); 2) retrolateral tibial apophysis (RTA) curved ventrally in retrolateral view (Fig. 25 C), vs anteriorly extending before curved ventrally (Peng 2020: fig. 296 b); 3) presence of a pair of atrial ridges (AR) (Fig. 25 D), vs absent (Peng 2020: fig. 296 f).

Eye sizes and interdistances: AME 0.41, ALE 0.21, PLE 0.19, AERW 1.16, PERW 1.37, EFL 0.94. Legs: I 4.16 (1.35, 0.70, 0.95, 0.73, 0.43), II 3.23 (1.00, 0.50, 0.75, 0.63, 0.35), III 4.07 (1.13, 0.48, 1.18, 0.85, 0.43), IV (1.50, missing, missing, missing, missing).

Dorsum of abdomen dark, mingled with green, with irregular anterior scutum ~ 1 / 3 abdominal length; venter colored as dorsum.

Palp (Fig. 25 A – C): femur length / width ratio ca 2.5; patella ~ 1.2 × longer than wide in retrolateral view; tibia ~ as long as wide in retrolateral view; retrolateral tibial apophysis (RTA) strongly sclerotized, curved ventrally to rather pointed tip in retrolateral view; cymbium pale yellow, ~ 1.6 × longer than wide; tegulum length / width ratio ca 1.53, with posteriorly extended posterior lobe (PL) with blunt end, and sub-spherical retrolateral tegular bump (TB); embolus (E) originating from most anterior portion of tegulum, slightly curved, and with blunt end.

Female (Figs 25 D, E, 26 C). Total length 5.14. Carapace 2.29 long, 1.67 wide. Abdomen 2.90 long, 1.81 wide. Eye sizes and interdistances: AME 0.43, ALE 0.26, PLE 0.26, AERW 1.48, PERW 1.60, EFL 1.05. Legs: I 4.61 (1.55, 0.68, 1.10, 0.83, 0.45), II 3.91 (1.25, 0.63, 0.88, 0.75, 0.40), III 4.64 (1.38, 0.63, 1.00, 1.13, 0.50), IV 6.18 (1.68, 0.80, 1.50, 1.70, 0.50). Carapace (Fig. 26 C) similar to that of male. Dorsum of abdomen (Fig. 26 C) with inconsecutive, anterior, orange, arc-shaped setal stripes followed by alternate pale and dark setal patches; venter dark.

Epigyne (Fig. 25 D, E) sub-triangular; atrium (At) anteriorly located, with arc-shaped lateral ridges (AR); copulatory openings (CO) small, partly visible; copulatory ducts (CD) thick, posteriorly extended; spermathecae (S) touching each other, spherical.
