Type material.
Holotype ♀ (TRU - JS 0765), China: • Yunnan Province, Dehong Dai Autonomous Prefecture, Yingjiang County, Tongbiguan Township, Banggetong (24°35.96'N, 97°38.48'E, elevation undetailed) 3. V. 2024, H. Qiu leg. Paratypes • 3 ♂ (TRU - JS 0766–0768), same data as for holotype.
Etymology.
The species name comes from the type locality, Yingjiang County; noun in apposition.
Diagnosis.
Pancorius yingjiang sp. nov. resembles that of P. manipuriensis (Biswas & Biswas, 2004) in having a similar male palp and a small, anteriorly located epigynal hood (H), but can be easily distinguished by the following: 1) copulatory openings (CO) opened anteriorly (Fig. 22 A, B) vs opened opposite (Caleb 2023: figs 21, 22); 2) epigynal hoods (H) posterior to copulatory openings (CO) (Fig. 22 A, B) vs lateral to copulatory openings (Caleb 2023: figs 21, 22); 3) retrolateral tibial apophysis (RTA) directed towards ca 12 o’clock position in ventral view (Fig. 21 B) vs ca 2 o’clock position (Caleb 2023: fig. 15).
Description.
Female (Figs 21 E – H, 22). Total length 6.40. Carapace 3.03 long, 2.40 wide. Abdomen 3.23 long, 2.43 wide. Eye sizes and interdistances: AME 0.72, ALE 0.43, PLE 0.38, AERW 2.30, PERW 2.20, EFL 1.40. Legs: I 6.16 (1.88, 1.18, 1.50, 1.00, 0.60), II 5.56 (1.63, 1.10, 1.25, 0.95, 0.63), III 6.61 (2.13, 1.00, 1.45, 1.35, 0.68), IV 6.97 (2.13, 0.98, 1.55, 1.63, 0.68). Carapace yellow-brown, covered with dark golden and pale setae, with irregular yellow area anteriorly on thoracic part. Chelicerae brawny, with two promarginal teeth and one retromarginal tooth. Legs pale, mingled with red-brown, spiny. Dorsum of abdomen dark and spotted laterally, with central, longitudinal, pale stripe and two pairs of median muscle depressions; venter dark centrally, with pair of dotted lines.
Epigyne (Fig. 22 A – D) with pair of anterior, small hoods (H) below copulatory openings (CO); copulatory openings slit-shaped, opened anteriorly, and apart from each other <1 / 2 their width; copulatory ducts (CD) broad, with small, mediolateral accessory glands (AG); spermathecae (S) almost round, touching each other.
Male (Fig. 21 A – D). Total length 5.23. Carapace 2.66 long, 2.14 wide. Abdomen 2.63 long, 1.60 wide. Eye sizes and interdistances: AME 0.66, ALE 0.40, PLE 0.37, AERW 2.06, PERW 1.97, EFL 1.26. Legs: I 6.84 (2.00, 1.08, 1.78, 1.25, 0.73), II 5.64 (1.75, 0.90, 1.33, 1.03, 0.63), III 6.54 (2.08, 0.90, 1.38, 1.45, 0.73), IV 6.82 (2.03, 0.85, 1.43, 1.58, 0.93). Habitus (Fig. 21 D) similar to that of female except carapace darker, and without central, longitudinal, pale stripe on dorsum of abdomen.
Palp (Fig. 21 A – C): femur length / width ratio ca 3.34; patella ~ 1 / 2 femoral length; tibia slightly longer than wide, with strongly sclerotized, tapered retrolateral apophysis (RTA) curved distally and with pointed tip; cymbium ~ 1.5 × longer than wide; tegulum slightly swollen posteriorly, with well-developed posterior lobe (PL) with blunt end; embolus (E) arising from anteroprolateral portion of tegulum, with median sub-triangular extension and pointed end.
Distribution.
Known only from the type locality in Yunnan, China (Fig. 48).
Comments.
As the female can be more easily distinguished from other congeners than the male, it is proposed as the holotype.
