Etymology.

The specific name is after the type locality, Hainan; noun in apposition.

Diagnosis.

Simaetha hainan sp. nov. resembles that of S. cheni Wang & Li, 2021 , in having the blade-shaped retrolateral tibial apophysis ( RTA), the presence of antero-marginal protuberances on anterior surface of chelicerae, but differs in: 1) embolus (E) straight (Fig. 27 A View Figure 27 ) vs curved prolaterally at distal portion ( Wang and Li 2021: fig. 18 B); 2) tibia slightly longer than wide in retrolateral view (Fig. 27 B View Figure 27 ) vs wider than long ( Wang and Li 2021: fig. 18 C); 3) epigynal hood (H) posteriorly located, and approximately half the length of anterior chamber of spermatheca (Fig. 28 A View Figure 28 ) vs anteriorly located and <1 / 4 length of anterior chamber of spermatheca ( Wang and Li 2021: fig. 19 A, B).

Description.

Male (Figs 27 View Figure 27 , 28 C, D, F, G View Figure 28 ). Total length 2.74. Carapace 1.32 long, 1.08 wide. Abdomen 1.50 long, 1.06 wide. Eye sizes and interdistances: AME 0.32, ALE 0.16, PLE 0.16, AERW 0.90, PERW 1.04, EFL 0.64. Legs: I 2.41 (0.78, 0.50, 050, 0.33, 0.30), II 1.76 (0.53, 0.30, 0.38, 0.30, 0.25), III 1.63 (0.50, 0.25, 0.33, 0.30, 0.25), IV 2.06 (0.73, 0.30, 0.45, 0.33, 0.25). Carapace red-brown, covered with pale and golden scales, with central dark patch on cephalon. Chelicerae red-yellow, with base-lateral protuberances on anterior surface, two promarginal teeth and one retromarginal fissidentate tooth with two cusps. Leg I robust, with enlarged femora, and three and two pairs of ventral spines on tibiae and metatarsi, respectively. Dorsum of abdomen red-brown, covered completely by large scutum; venter brown, with two pairs of dotted lines medially.

Palp (Fig. 27 A – C View Figure 27 ): femur length / width ratio ca 3.2; patella ~ 1.5 × longer than wide in retrolateral view; tibia slightly longer than wide, with lamellar retrolateral apophysis ( RTA) acutely narrowed at distal portion and blunt apically in dorsal view; cymbium ~ 1.8 × longer than wide, with baso-retrolateral process (CP); tegulum oval; embolus (E) originating at ca 10: 30 o’clock position, straight, tapered to rather blunt tip.

Female (Fig. 28 A, B, E View Figure 28 ). Total length 3.16. Carapace 1.34 long, 1.07 wide. Abdomen 1.95 long, 1.08 wide. Eye sizes and interdistances: AME 0.32, ALE 0.17, PLE 0.17, AERW 0.97, PERW 1.08, EFL 0.74. Legs: I 2.11 (0.75, 0.45, 0.38, 0.28, 0.25), II 1.89 (0.58, 0.35, 0.38, 0.33, 0.25), III 1.68 (0.50, 0.25, 0.35, 0.33, 0.25), IV 2.24 (0.83, 0.28, 0.50, 0.38, 0.25). Habitus (Fig. 28 E View Figure 28 ) similar to that of male except without base-lateral protuberances on anterior surface of chelicerae.

Epigyne (Fig. 28 A, B View Figure 28 ) ~ 1.7 × wider than long, with posterior, sub-triangular hood (H) ~ 1 / 2 length of anterior chamber of spermatheca ( AS); copulatory openings (CO) lateral to hood; copulatory ducts ( CD) slightly curved medially, connected to antero-inner portions of anterior chamber of spermatheca, with small terminal accessory glands ( AG); spermathecae (S) divided into oval anterior chamber extended posteriorly and spherical posterior chamber ( PS); fertilization ducts ( FD) arising from antero-inner portions of posterior chamber of spermatheca.

Distribution.

Known only from the type locality in Hainan, China (Fig. 48 View Figure 48 ).
