Type material.
Holotype ♂ (TRU - JS 0730), China: • Hainan Province, Baoting Li and Miao Autonomous County, Maogan Township, 124 road (18°39.32'N, 109°32.45'E, ca 530 m), 4. VIII. 2023, C. Wang et al. leg. Paratypes • 1 ♂ (TRU - JS 0731), same data as for holotype; • 2 ♀ (TRU - JS 0823, 0824), same locality as for holotype, 4. IX. 2024, C. Wang and S. K. Li leg.
Etymology.
The specific name refers to the short name of type locality (Hainan Province); noun in apposition.
Diagnosis.
Dendroicius qiong sp. nov. resembles D. hotaruae in having similar habitus and copulatory organs, especially the presence of a pair of white lateral setal stripes across the whole surface of carapace, but can be easily distinguished by the absence of latero-terminal tibial apophysis and mesal branch of dorsal tibial apophysis (Fig. 3 C) vs present (Lin and Li 2020: fig. 3 C) and by the distance between copulatory openings (CO), which is ~ 3 / 4 of epigynal width, and the C-shaped copulatory ducts (CD) (Fig. 4 A – C) vs distance between copulatory openings ~ 1 / 3 of epigynal width, and nearly S-shaped copulatory ducts (Lin and Li 2020: fig. 4 A, B).
Description.
Male (Figs 3, 4 D, E, G, H). Total length 2.91. Carapace 1.40 long, 0.89 wide. Abdomen 1.53 long, 0.80 wide. Eye sizes and interdistances: AME 0.28, ALE 0.14, PLE 0.13, AERW 0.80, PERW 0.84, EFL 0.47. Legs: I 2.19 (0.68, 0.45, 0.53, 0.33, 0.20), II 1.74 (0.53, 0.33, 0.38, 0.30, 0.20), III 1.63 (0.55, 0.25, 0.30, 0.33, 0.20), IV 2.19 (0.70, 0.33, 0.53, 0.40, 0.23). Carapace almost rectangular, yellow-brown except eye field dark, covered with dense dark setae; fovea indistinct. Chelicerae red-brown, with two promarginal teeth and one retromarginal tooth. Legs pale except femora dark brown, with two pairs of spines on tibiae and metatarsi I. Dorsum of abdomen grey, with six longitudinal, dark green and green-brown stripes extending across complete surface; venter pale.
Palp (Fig. 3 A – C): femur length / width ratio ca 2.0; patella almost as long as wide in retrolateral view; tibia almost as long as patella in retrolateral view; retrolateral tibial apophysis (RTA) lamellar, with dorsal spinous denticle (DD); dorsal tibial apophysis (DTA) wider than long, with several anteromarginal denticles; cymbium ~ 1.8 × longer than wide, with almost horizontal tip and flat baso-retrolateral process (CP); tegulum elongate-oval, swollen at posterior half, with irregular anterior lobe (TL) and small disto-retrolateral bump (TB); embolus (E) strongly sclerotized, tapered, almost as long as anterior tegular lobe, slightly curved medially and pointed apically.
Female (Fig. 4 A – C, F). Total length 2.66. Carapace 1.12 long, 0.77 wide. Abdomen 1.64 long, 0.80 wide. Eye sizes and interdistances: AME 0.26, ALE 0.13, PLE 0.12, AERW 0.70, PERW 0.74, EFL 0.49. Legs: I 1.49 (0.48, 0.28, 0.30, 0.25, 0.18), II 1.31 (0.40, 0.28, 0.25, 0.20, 0.18), III 1.41 (0.45, 0.20, 0.30, 0.28, 0.18), IV 1.99 (0.63, 0.30, 0.48, 0.35, 0.23). Habitus (Fig. 4 F) similar to that of male except paler and with pair of longitudinal, white setal stripes laterally on carapace.
Epigyne (Fig. 4 A – C) wider than long, with posterior concave> 3 × wider than long; atrium (At) oval, paired, with anterior arc-shaped ridges (AR); copulatory openings (CO) almost round, laterally opened, separated from each other ~ 3 / 4 epigynal width; copulatory ducts (CD) curved into C-shape, and with small terminal accessory glands (AG); spermathecae (S) elongated.
Distribution.
Known only from the type locality in Hainan, China (Fig. 47).
