Note.

In the entry for P. atrata , WSC (2023) refers to Schenkel’s (1951: 25 [♀]) record of P. lapponica (Thorell, 1872) from Banff National Park (Alberta, Canada) as belonging to P. atrata . Schenkel (1951) compared his specimens (females) with those from the eastern Alps (Tyrol). In fact, P. lapponica is absent in the Alps, but there exists the closely related species, P. cincta ( Kulczyński, 1887), which was earlier considered as a junior synonym of P. lapponica . On the other hand, P. lapponica in the Nearctic is restricted to the north (north of 58°N; Dondale and Redner 1986), and P. concinna (Thorell, 1877), the only similar species with an almost identical epigyne, is known in southern Canada and even reaches the highlands in New Mexico ( Dondale and Redner 1986). Therefore, Schenkel’s (1951) record of P. lapponica most likely refers to P. concinna and not to P. atrata , which is unknown from the Nearctic or the European Alps.

Diagnosis.

This species differs from other Pardosa atrata -group species in having the shortest tegular apophysis (cf. Fig. 3E-G ) and receptacles of intermediate length (Fig. 5A-I ). The epigyne of P. atrata differs from that of P. armeniaca sp. nov. in having the receptacles roundly bent (vs straight), and P. atrata can be distinguished from the Nearctic P. fuscula by the relatively shorter receptacles (cf. Fig. 5F and I ), as well as by the base of septum, which has well-developed, rounded margins (Bm) (vs stem gradually turns to the base).

Description.

See Holm (1947) and Almquist (2005).

Comments.

Two names Pardosa narymica and P. atrata are synonymised here based on the similarity of the epigynes. Pardosa narymica was described based on the holotype female and male paratype from East Kazakhstan Oblast. The types of this species were lost (destroyed) during shipment (Ovtsharenko pers. comm.). Judging from the original figures, the male was mismatched with the female; the male it has tegular apophysis like in P. lapponica (Thorell, 1872) and was an undescribed, related species occurring in the region (personal data). In addition, P. atrata is known in the adjacent Altai ( Azarkina and Trilikauskas 2013). On the other hand, P. camtschadalica synonymized by Kulczyński (1926) without comparison with P. atrata may be a valid species.

Type locality.

The types are from Sweden, Härjedalen Province (ca 62.26°N, 13.5°E, several syntypes) and one female is from Finnish Lapland (ca 68.448°N, 22.484°E) ( Thorell 1873).

Distribution.

Pardosa atrata has a trans-Palaearctic distribution and while restricted to the north in Europe, it occurs rather far south in Asia, reaching Inner Mongolia (Fig. 6 ). The southernmost localities in Europe lie at about 54°N (Fig. 6 ). The record from Moscow Oblast ( Sytshevskaja 1935) is doubtful and not confirmed by museum specimens or recent records (Mikhailov pers. comm.).
