Longicoelotes karschi , new species Figures 310–322

Coelotes mollendorffi: Schenkel, 1963: 280 , fig. 158. – Chen and Zhang, 1991: 187, fig. 185 (misidentification).

Coelotes moellendorffi: Song et al., 1999: 376 , figs. 221E, 221F, 222M, 224A (misidentification).

TYPE: Male holotype from Zijin (Purple) Mt., 350–450 m, Nanjin, China (September 13, 1997; X. P. Wang), and female paratype from same locality (October 9, 1988; P. Beron), deposited in AMNH .

DIAGNOSIS: This species can be easily identified by the absence of epigynal teeth, the distinct shape of the epigynum, the short copulatory ducts, and the distinct spermathe­ cal stalks and bases of females (figs. 310, 311), and by the strongly elongated patellar apophysis, complex conductor, and the small median apophysis of males (figs. 312–314).

DESCRIPTION: Male (holotype): Total length 7.70. Eye sizes and interdistances: AME 0.15, ALE 0.18, PME 0.18, PLE 0.17, AME­AME 0.08, AME­ALE 0.03, ALE­ PLE 0.03, PME­PME 0.10, PME­PLE 0.12, AME­PME 0.15. Leg measurements: I, 13.5 (3.42, 4.46, 3.40, 2.18); II, 12.1 (3.20, 3.84, 3.10, 1.92); III, 11.3 (3.00, 3.40, 3.26, 1.62); IV, 15.6 (4.00, 4.80, 4.60, 2.20). Male palp with patellar apophysis strongly elongated; RTA long, with distal end slightly extended beyond tibia; lateral tibial apophysis situated relatively dorsally; cymbial furrow short; conductor short, broad, bifurcated, with dor­ sal one broad and ventral one slender; conductor lamella less developed; conductor dorsal apophysis broad; median apophysis small, not spoonlike; embolus basal in origin, moderately long, linear (figs. 312–314).

Female (paratype): Total length 7.80. Eye sizes and interdistances: AME 0.15, ALE 0.20, PME 0.19, PLE 0.19, AME­AME 0.10, AME­ ALE 0.04, ALE­PLE 0.05, PME­PME 0.11, PME­PLE 0.17, AME­PME 0.16. Leg measurements: I, 12.1 (3.24, 4.20, 2.86, 1.82); II, 10.8 (3.00, 3.60, 2.60, 1.58); III, 10.1 (2.80, 3.10, 2.72, 1.44); IV, 13.9 (3.60, 4.46, 4.00, 1.80). Clypeal height roughly twice AME diameter or slightly shorter; chilum divided, elongated (fig. 315). Chelicerae with three promarginal, two retromarginal teeth (fig. 316). Labium slightly wider than long. Length of fe­ male 1st leg patella + tibia longer than carapace length. Epigynum with epigynal teeth absent; middle part of epigynum relatively elevated with clear lateral edges; atrium reduced, not apparent; copulatory ducts short; sperma­ thecal heads pointed laterally; spermathecae with distinct stalks and bases; spermathecal stalks situated medially, close to each other; spermathecal bases large, widely separated (figs. 310, 311).

Tarsal organ situated close to distal end of tarsus, slightly anterior of most distal trichobothrium (figs. 317–319). Only female spinnerets examined: apex of ALS with 2 major ampullate gland spigots (MAP), about 25–31 piriform gland spigots; PMS with 1 or 2 minor ampullate gland spigots (mAP) and about 16–20 aciniform gland spigots, 2 cylindrical gland spigots (CY); PLE with about 22 aciniform gland spigots and 2 cylindrical gland spigots (figs. 320–322).

NOTES: Examination of the types of C. mollendorffi (3 female syntypes from Peking, China, in ZMB, examined) shows that C. mollendorffi is in fact a junior synonym of Paracoelotes spinivulvus (Simon, 1880) .

OTHER MATERIAL EXAMINED: CHINA: Zhejiang: West Tschenkiang , April 1872, 1 female (A. David, MNHN, B2011 bis) ; Hangtscheou , 1925, 3 females ( MNHN, B2011 bis) ; Lin­An, October 19, 1974, 3 males and 3 females (C. D. Zhu, NBUMS) .

DISTRIBUTION: China (Jiangsu, Zhejiang).
