1. Arctogeophilus glacialis (Attems, 1909)

Geophilus (Arctogeophilus) glacialis Attems 1909: 23.

Arctogeophilus glacialis - Attems 1929: 297; Chamberlin 1946: 182.

Cryophilus alaskanus Chamberlin 1919: 18 (synonymy by Chamberlin 1946: 182).

Type localities.

Russia: Chukotka autonomous okrug: “Nunamo” ( Attems 1909; see Remarks), "Konyam Bay im Senjavin Sund" ( Attems 1909) = Penkigney Bay, ca 64°49'N, 172°53'W; USA: Alaska: "Port Clarence" ( Attems 1909), ca 65°15'N, 166°51'W.

Type series.

Syntypes: 7 specimens, including 3 males and 4 females. Deposited in NHMW ( Ilie et al. 2009).

Diagnosis.

A species of Arctogeophilus with first maxillary lappets relatively short; denticles on all forcipular articles; denticles on the forcipular intermediate articles only slightly shorter than those on trochanteroprefemur and tarsungulum; 39 leg-bearing segments, possibly invariably; ventral pore-fields absent; pretarsus of ultimate legs absent.

Distribution.

Far East: Chukotka autonomous okrug ( Attems 1909). Outside Asian Russia: Alaska and Canada (e.g., Attems 1909; Chamberlin 1946; Langor and Langor 2022).

Remarks.

The position of the locality “Nunamo” (indicated by Attems 1909) is uncertain: the original material was collected during the Vega expedition, and Nordenskiöld (1882: 565, 567) mentioned a tent-village “Nunamo” located in Chukotka, but he did not indicate the precise position of this place. Instead, Nordenskiöld (1882: 565) provided coordinates for "Konyam Bay" = Penkigney Bay.
