Type material. Pardosa paratesquorum: Lectotype ♂ without specified locality, in MNHN, examined and here designated (see Comments below).
Pardosa daqingshanica: Holotype from CHINA, Inner Mongolia, Daqing Shan Mts. Originally placed in Dept of Zoology, Inner Mongolia Normal University, Huhhot, China, now in IZAS, not examined. Paratypes 2♂ 1♀ from CHINA, Inner Mongolia, Mt. Daqing Shan (40°36'N 110°42'E), 25 May 1993 (G Tang), in IZAS, examined.
Other material examined. CHINA. Shanxi: Hongtong County, Mt. Huo Shan (36°24'N 111°48'E), 12 May 1988 (W. Huang, IZAS), 1♂ 2♀.
Comments. This species is excluded from the tesquorum group because of lacking a basally directed paleal process as well as by deviant conformation of embolus and conductor. It is redescribed here because of previous confusion.
As stated above, the female that was originally (Schenkel 1963), with some doubt, assigned to P paratesquorum in fact belongs to another species (here described as P. zyuzini sp. nov.). Yu et al. (1987) already described and illustrated the proper female of P. paratesquorum.
The type material of P. paratesquorum in MNHN consists of two glass vials, one with a male having the right palp detached and the left palp intact, as well as another with a female having the epigyne intact. The detached male palp has now been studied (Fig. 107) and found to be consistent with Schenkel’s (1963, fig. 208a) illustration of P. paratesquorum. The male is placed in a small glass vial with a label "35". This vial is kept in a larger glass vial with labels " Pardosa paratesquorum Schkl Type ", "Assongue du Chajaud" [sic, recte: "Chazaud"], "Potanin 35", and "Schenkel det 1946". The labels in the vial indicate two different places of origin, cf. Schenkel 1963, pointing at some confusion in the material: Assonge is likely to be situated at river Tuul in Mongolia, where one male and the single (non-conspecific) female were captured, while "Potanin 35" is likely to refer to a locality in Gansu, China (Schenkel 1963). It is probable that the label "Assongue du Chajaud" has been misplaced and should belong to the vial with the female specimen. The latter vial now only contains the label " Pardosa paratesquorum Schkl Type (♀)". The male we examined certainly belongs to the original material, and we designate it as the lectotype of P. paratesquorum Schenkel.
Diagnosis. Males are distinguished by the configuration of the bulbus, notably the complex shape of the apical part of the conductor (Fig. 109); females by the configuration of the epigyne (Fig. 111).
Description. Male (from Inner Mongolia). Total length 5.8. Carapace 3.05 long, 2.30 wide.
Prosoma. Carapace (Fig. 4) sooty brown with lighter median band and lateral bands broken into lighter patches. Thoracic part with recumbent dark pubescence (light hairs seem to have gone in the specimens at hand). Clypeus yellowish. Chelicerae brownish with sooty streaks, inner side lighter, retromargin with 3 teeth (in lectotype the inner and middle one nearly fused). Sternum brownish grey to blackish.
Eyes. Width of row I 50 (slightly procurved when seen from in front), row II 72, row III 94, row II-III 70. Diameter of AME 10, ALE 9, PME 25, PLE 22. Distance between AMEs 8, between AME and ALE 2.
Opisthosoma. Dorsum (Fig. 4) more or less sooty brown, with lighter brown lanceolate stripe followed by a series of transversally arranged light patches, posterior confluent to bars, each patch with a black dot. Venter light to greyish brown with light recumbent pubescence.
Legs (Table 1). Yellow with sooty pseudoannulation dorsally on all femora (Fe I with confluent sooty patch dorsally in proximal half). Hairiness in leg I similar to that of the other legs. Ti I retrolaterally with two spines or only one in proximal half.
Palp (Figs 107-109, 112-114). Pt 0.60, Ti 0.60, Cy 1.35. Femur and tibia mostly sooty with dark yellowish longitudinal streaks. Patella dorsally mostly yellowish. Cymbium dark brownish, distally lighter. Tibia with dense dark pubescence. Tegular apophysis stout, evenly and strongly bent backwards (Figs 108, 114). Terminal part with curved, strongly sclerotized ridge in the palea (Fig. 112, arrow), continuing into conductor. Latter with uniquely complex apical portion (Figs 109, 112-113). Embolus long and comparatively stout (Figs 112-113).
Female (from Shanxi). Total length 7.0. Carapace 3.80 long, 2.90 wide.
Prosoma and opisthosoma. Carapace brownish with lighter median band narrowing at thoracic/cephalic junction, then widening in postocular area. Light lateral bands broken into patches, posterior one longest. Opisthosoma dorsally dark greyish, lanceolate stripe brownish.
Eyes. Width of row I 59 (slightly procurved when seen from in front), row II 90, row III 120, row II-III 87. Diameter of AME 12, ALE 11, PME 36, PLE 30. Distance between AMEs 8, between AME and ALE 3.
Legs (Table 1). Yellowish-brown. Femora with darker pseudoannulation. Ti retrolaterally with one spine in proximal half.
Epigyne (Figs 110-111, 115). Cavity deep, divided by septum. Anterior part of septum wider than posterior. Receptacula unusually short. Spermathecae not reaching level of cavity.
Size variation. Carapace length: males 2.95-3.10 (n=3), females 3.40-3.80 (n=3).
Habitat. Not known.
Distribution (Fig. 116). China (Inner Mongolia, Beijing, Hebei, Shanxi, Gansu, Qinghai (Song et al. 2001)). Because of previous confusion with P zyuzini sp. nov. some records need to be verified.
