Pardosa tesquorumoides Song & Yu, 1990: 79, figs 10–13 (♂); Yin et al. 1997: 209, figs 98a–e (♂); Song et al. 1999: 334, figs 199B, J (♂); Song et al. 2001: 256, figs 159A–D (♂); Hu 2001: 204, figs 104. 1–4 (♂).
Type material. Holotype ♂ and allotype ♀ from CHINA, Qinghai: Menyuan. Originally placed in Bethune Medical University, now in Jinlin University, not examined. Paratype ♀ from CHINA, Sichuan: Batang, in IZAS, not examined.
Material examined. CHINA: Sichuan: Kangding County, Mt. Zheduo Shan (30°24'N 101°41'E), 4200 m, 20 Aug. 1983 (IZAS), 13 2♀; Hongyuan County (32°42'N 102°29'E), 3000 m, 17 June 1985 (IZAS), 23 2♀.
Remark. Types were not available to us but drawings of this species (references above) are adequate and well illustrate the species-specific characters in the copulatory organs.
Diagnosis. Males can be distinguished from other members of the group by the configuration of the large tegular apophysis (Figs 83, 93) and the distinct, protruding, hooked terminal apophysis (Figs 85, 90). Females can be easily recognized by the amphoral shape of the epigynal septum (Figs 21, 88), which does not fill out the epigynal cavities in the anterior half (cf. P. zyuzini sp. nov.) and the somewhat protruding condition of the anterior part of the septal stem.
Description. Male (from Sichuan, Hongyuan County). Total length 4.9. Carapace 2.65 long, 1.90 wide.
Prosoma. Carapace (Fig. 5) dusky brown with yellowish brown median band in thoracic part and yellow brown lateral, unbroken bands. Thoracic part with recumbent black hairs, in bands also with whitish hairs. Clypeus dusky yellowish. Chelicerae dusky yellowish with greyish streaks; hairs dark; retromargin with 2 teeth (in one male one chelicera with 2 the other with 3 teeth). Sternum yellowish grey with numerous light hairs and a few dark, erect ones.
Eyes. Width of row I 40 (slightly procurved when seen from in front), row II 61, row III 80, row II–III 59. Diameter of AME 9, ALE 8, PME 23, PLE 18. Distance between AMEs 6, between AME and ALE 2.
Opisthosoma. Dorsum (Fig. 5) greyish, with dark-bordered greyish-brown lanceolate stripe. Longitudinal greyish-yellow band encompassing lanceolate stripe, posteriorly formed by pairs of greyish yellow spots or, when confluent, bars. Each spot laterad dark greyish and with a stout, erect black hair in the middle. Dorsum with black hairs and, in lighter parts, with recumbent light hairs. Venter light greyish brown with recumbent light hairs.
Legs (Table 1). Yellowish brown. Fe dorsally more or less sooty with longitudinal yellowish markings. Leg I without deviant pilosity. TiI with 2 retrolateral spines.
Palp (Figs 83–87, 90–93). Pt 0.50, Ti 0.45, Cy 1.05. Fe and Ti sooty brown with longitudinal dusky yellowish streaks, Pt dorsally dusky yellowish, Cy in basal part sooty brown, in distal part brown. All segments with dark hairs. Tegular apophysis stout, long and evenly curved (Figs 83, 93). Terminal part with hooked terminal apophysis (Figs 85–87, 90–92). Conductor as in Figs 90–91. Basal paleal process small, triangle-shaped (Figs 85, 90–91). Embolus laminar, grooved along its length, ventral edge turned forwards except distally, tip truncated with shallow concavity (Figs 85–86, 90, 92).
Female (from Sichuan, Kangding County). Total length 5.4. Carapace 2.70 long, 2.05 wide.
Prosoma and opisthosoma (Fig. 6). Coloration lighter and pattern more contrasting than in the male. Carapace with bright yellow median band and yellow unbroken lateral bands. Clypeus yellow. Chelicerae yellow with slightly darker veins; retromargin with 2 teeth. Abdomen patterned as in the male, lanceolate stripe, median band (incl. spots) and venter yellowish.
Eyes. Width of row I 41 (slightly procurved when seen from in front), row II 56, row III 74, row II–III 56. Diameter of AME 9, ALE 8, PME 21, PLE 17. Distance between AMEs 6, between AME and ALE 2.
Legs (Table 1). Pt–Ta light brownish with very faint traces of annulation. Fe yellowish brown with dark blotches dorsally and very faint greyish tinge laterally and ventrally.
Epigyne (Figs 21, 27, 88–89). Septum elongated, amphoral-shaped, narrow in anterior half, abruptly widened in posterior half. Edges of lateral elevations marked. Spermathecae ovoid (Fig. 89).
Size variation. Carapace length: males 2.45–2.65 (n=3), females 2.55–2.85 (n=4).
Habitat. Not known.
Distribution (Fig. 116). According to Song et al. (1999, 2001), P. tesquorumoides should occur in Mongolia and China (Inner Mongolia, Beijing, Xinjiang, Qinghai, Tibet, Sichuan). However, this species seems to be confined to high altitudes, so records from Xinjiang and Beijing are questionable and need confirmation. Records of this species from Xinjiang may refer to P. z y u z i n i sp. nov. Records from Inner Mongolia (Song et al. 1999) and from Mongolia (Song & Yu 1990) probably refer to a misinterpretation of Schenkel's illustration (1963, fig. 208b), which in fact shows an epigyne of P. z y u z i n i sp. nov.
