Type material

Holotype: male, CHINA: Nan-Shan-Kou , Tjan-Shan , 10 June 1877, M.G. Potanin leg. ( ZIP 164 ).

Additional material examined

CHINA: Xinjiang Uyghur: 1 ♀, Kashi (Kashgar), 5 July 1975 ( IOZB) ; 1 ♀, Kashi (Kashgar), 15 July 1996. ( IOZB 107 ) ; 1 ♂, 1 ♀ and 2 juveniles, Jarkend, 1909, G. Raquelle leg. ( NRM) ; 1 ♀, Turpan, Jh. Basfus leg. ( ZMB) ; 2♀♀, (Label: Turkestan): Kashgar. ( SMF 6085 About SMF ) ; 1 ♂, 1 immature ♀, Kashgar, E. Turkestan D. Lamsdell leg. ( NHM 1889.4.25.2-3) .

Diagnosis

Males of E. potanini are characterized by a combination of characters including beaklike dRTA, a deep retro-lateral incision at proximal part of cymbium ( Figure 17C View Figure 17 ) and a broad retrolatero-distad embolus tip ( Figure 17E View Figure 17 ); in female epigyne, EFB present but distinctly separated from AMLL, approximately as long as MS length ( Figure 17F View Figure 17 ).

Redescription

Male (n = 4) [Holotype first]. Males medium-sized. Total length: 14.2–17.3, prosoma length 7.4–7.8, prosoma width 6.2–6.6, anterior width of prosoma 3.1–3.3, opisthosoma length 6.8–9.5, opisthosoma width 4.4–5.1. Eyes of holotype: AME 0.47, ALE 0.44, PME 0.36, PLE 0.45; eye interdistances: AME–AME 0.22, AME–ALE 0.10, PME–PME 0.42, PME–PLE 0.46, AME–PME 0.31, ALE–PLE 0.21, clypeus height at AME 0.37, clypeus height at ALE 0.42.

Chelicerae with two anterior and four or five posterior teeth. Cheliceral furrow without denticles ( Figure 17B View Figure 17 ). Leg formula: 2 4 1 3. Measurements of palp and legs: Palp 10.3 [3.2, 1.5, 1.7, 3.9], I 35.6 [10.0, 3.4, 9.5, 9.3, 2.4], II 38.9 [10.6, 4.1, 10.7, 10.8, 2.7], III 31.6 [9.6, 3.4, 8.8, 8.5, 2.3], IV 36.6 [10.5, 3.4, 10.0, 10.3, 2.4].

Spination. Palp 131, 001, 1111; Legs: Femur I–III 323, IV 322 / 321; Patella I–IV 101; Tibia I–IV 2024; Metatarsus I–III 2024, IV 3034.

Palp. As in diagnosis with dRTA proximally wide and pointed distally, vRTA is triangular in ventral view ( Figure 17C View Figure 17 ).

Female (n = 6). Total length: 15.7–19.6, prosoma length 7.3–8.1, prosoma width 6.0–7.0, anterior width of prosoma 3.5–4.0, opisthosoma length 8.4–11.5, opisthosoma width 6.0–8.1. Eyes: AME 0.48, ALE 0.40, PME 0.38, PLE 0.43; eye interdistances: AME–AME 0.28, AME–ALE 0.13, PME–PME 0.47, PME–PLE 0.50, AME–PME 0.36, ALE–PLE 0.23, clypeus height at AME 0.38, clypeus height at ALE 0.43.

Chelicerae as in males. Cheliceral furrow without denticles. Leg formula: 2 4 1 3. Measurements of palp and legs: Palp 9.4 [2.8, 1.3, 1.7, 3.6], I 31.6[9.0, 3.8, 8.4, 8.3, 2.1], II 33.7 [9.8, 3.8, 9.2, 8.5, 2.4], III 28.4 [8.6, 3.4, 7.5, 6.7, 2.2], IV 32.2 [9.7, 3.2, 8.6, 8.3, 2.3].

Spination. Palp 131, 001, 1111, 1013; Legs: Femur I–III 323, IV 322; Patella I–IV 000; Tibia I–IV 2024; Metatarsus I–III 2024, IV 3034.

Epigyne / vulva. As in diagnosis with EF longer than wide, AMLL well developed anteriorly but not encircling MS entirely, EFB distinctly separated from AMLL ( Figure 17F View Figure 17 ); glandular pores located on a globular process of vulva ( Figure 17G View Figure 17 ).

Colouration [in ethanol]. Cream to dark yellow, ventral opisthosoma pale.

Remarks

The description and illustration of E. nanjiangensis (sub Heteropoda nanjiangensis ) by Hu and Fu (1985) as well as examination of the type series match fully with holotype male of E. potanini . Further females (along with sympatric males) examined from around the type locality, revealed conspecifity of them with the holotype female of E. nanjiangensis . Therefore, this species is proposed as a junior synonym of E. potanini .

Known geographical distribution

Autonomous region in Xinjiang Uyghur, China, the most northeastern distribution range of Eusparassus species.
