Type locality.

Russia: Republic of Tatarstan: Chistopolsky District: "Bliz s. Zmievo" ( Folkmanová and Dobroruka 1960) = near Zmievo village, ca 55°23'N, 50°43'E.

Type series.

Syntypes: 20 specimens. Depository unknown.

Diagnosis.

A species of Arctogeophilus with first maxillary lappets relatively long; denticles on all forcipular articles, those on intermediate articles smaller than those on trochanteroprefemur and tarsungulum; 35-43 leg-bearing segments; ventral pore-fields on some anterior segments; pretarsus of ultimate legs absent.

Distribution.

Western Siberia: Sverdlovsk, Chelyabinsk, Tomsk, and Kemerovo oblasts, Altai krai, republics of Altai and Khakassia ( Byzova and Chadaeva 1965; Zalesskaja et al. 1982; Farzalieva 2008; Nefediev et al. 2017a, 2017c, 2018, 2021; Nefediev 2019). Eastern Siberia: Republic of Tuva and Krasnoyarsk krai ( Zalesskaja et al. 1982; Vorobiova 1999; Rybalov 2002; Vorobiova et al. 2002). Far East: Jewish autonomous oblast, Amur oblast, Khabarovsk and Maritime krais, Chukotka autonomous okrug, and Sakhalin oblast (Sakhalin and Kunashir islands) ( Zalesskaja et al. 1982; Ganin 1997). Outside Asian Russia: westwards to Transcarpathia ( Zalesskaja et al. 1982; Volkova 2016) and Eastern Kazakhstan ( Dyachkov and Tuf 2019).

Remarks.

Zalesskaja et al. (1982: 189) suggested this species can be a junior synonym of A. glacialis (Attems, 1909), and this is still in doubt ( Nefediev et al. 2017a). Because of this uncertainty, the actual taxonomic status of the populations of Arctogeophilus from the Far East remains to clarify.

The type locality for A. macrocephalus has been sometimes reported erroneously in previous publications (e.g., Bonato and Minelli 2014).
