Type material.

Holotype ♀ ( TRU - JS 0737 ), China: • Yunnan Province, Menghai County, Menghai Township, Manliang Village (21°56.36'N, 100°28.37'E, elevation undetailed), 18. III. 2024, Hang Qiu leg. GoogleMaps Paratype • 1 ♂ ( TRU - JS 0738 ), same data as for holotype GoogleMaps .

Etymology.

The specific name is a patronym in honor of the collector; noun (name) in the genitive case.

Diagnosis.

The female of Irura qiuhangi sp. nov. resembles that of I. uniprocessa Mi & Wang, 2016 in having a similar atrium (At) and transversely extended anterior chamber of spermatheca ( AS), but can be easily distinguished by the rounded posterior chamber of spermatheca ( PS) (Fig. 8 B View Figure 8 ) vs elongated ( Mi and Wang 2016: figs 1 G, 2 e). The male of I. qiuhangi sp. nov. resembles that of I. shendurney Asima, Caleb & Prasad, 2024 in the point of origin of the embolus (E) and the form of cymbial process (CP), but can be easily distinguished by the absence of tibial apophysis (Fig. 7 B, C View Figure 7 ) vs retrolateral apophysis present ( Asima et al. 2024: figs 41, 44).

Description.

Female (Fig. 8 A, B, D – G View Figure 8 ). Total length 2.65. Carapace 1.34 long, 1.44 wide. Abdomen 1.38 long, 1.53 wide. Eye sizes and interdistances: AME 0.30, ALE 0.17, PLE 0.16, AERW 1.11, PERW 1.34, EFL 0.49. Legs: I 3.63 (1.05, 0.75, 0.98, 0.50, 0.35), II (0.75, 0.45, 0.45, 0.40, missing), III 2.12 (0.65, 0.38, 0.43, 0.38, 0.28), IV (0.88, 0.43, 0.53, missing, missing). Carapace orange-brown, with pair of round dots behind PMEs, followed by oval, brown patch, covered with pale brown long setae and scales. Chelicerae red-brown, incised on base of anterior surface, with two promarginal teeth and one retromarginal fissidentate tooth with four cusps. Leg I robust, with two pairs of ventral spines on tibiae and metatarsi. Abdomen oval, dorsum pale yellow, with two pairs of large depressions; venter pale, with small pale brown dots medially.

Epigyne (Fig. 8 A, B View Figure 8 ) ~ 1.8 × wider than long; atrium (At) almost square, divided by narrow septum (Se); copulatory openings (CO) beneath lateral portions of atrium; copulatory ducts ( CD) weakly sclerotized, curved at base, and connected to distal ends of junction ducts of spermathecae ( JS); spermathecae (S) divided into transversely extending, kidney-shaped anterior chamber ( AS) and round posterior chamber ( PS); fertilization ducts ( FD) originating from antero-inner portions of posterior chamber of spermatheca.

Male (Figs 7 View Figure 7 , 8 C View Figure 8 ). Total length 2.62. Carapace 1.38 long, 1.58 wide. Abdomen 1.35 long, 1.68 wide. Eye sizes and interdistances: AME 0.31, ALE 0.18, PLE 0.17, AERW 1.19, PERW 1.50, EFL 0.61. Legs: I 4.75 (1.50, 1.15, 1.00, 0.65, 0.45), II 2.68 (0.90, 0.50, 0.50, 0.48, 0.30), III 2.19 (0.75, 0.38, 0.38, 0.40, 0.28), IV 2.70 (0.90, 0.50, 0.50, 0.50, 0.30). Carapace (Fig. 8 C View Figure 8 ) red-brown, with central irregular dark patch on cephalon, covered with dense thin setae and scales. Abdomen (Fig. 8 C View Figure 8 ) oval, dorsum with irregular brown patch, and without similar large shallow depressions as in female; venter brown.

Palp (Fig. 7 A – C View Figure 7 ): femur length / width ratio ca 2.8; patella ~ 1.4 × longer than wide; tibia slightly longer than wide, lacking apophyses; cymbium ~ 2 × longer than wide, with sizeable baso-retrolateral process (CP) curved medially and with pointed end; tegulum flat, almost round, with sperm duct (SD) extending along submargin; embolus (E) originating at ca 10 o’clock position, ~ 5 / 6 tegular length, flagelliform.

Distribution.

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

Comments.

As the female can be more easily distinguished from other congeners than the male, it was chosen as the holotype.
