Types.

Holotype ♂ (ZMMU), Russia, Wrangel Isl., the upper reaches of Neizvestnaya River, 71°12.933'N, 179°19.353'W, 128 m, steppe-like mound #2, 06.VII-03.VIII.2006, leg. O.A. Khruleva. Paratypes: 1♂ (ZMMU), same locality, steppe-like, mound #3, 03.VII.-03.VIII.2006, leg. O.A. Khruleva; 2 ♂ (ZMMU, paratypes of D. hyperboreus ) Wrangel Isl., lower reaches of Gusinaya River, gravel hilltop, 2.VII. 1984, leg. O.A. Khruleva; 1♂, 1♀ (ZMMU), middle reaches of Mamontovaya River, 22.VII-5.VIII.2015, leg. O.A. Khruleva.

Note.

Since a single female of this species was used to obtain SEM photographs, its technical description was impossible to produce.

Diagnosis.

Dactylopisthoides wrangelianus is most similar to D. hyperboreus (see above for diagnostic characters). From D. transbaicalicus , it differs in having a wider and shorter dorsal tibial outgrowth (cf. Fig. 2B View Figure 2 and figs 40, 41, 43, 44 in Marusik et al. [2001]) and a well-developed radical tooth of the embolic division (cf. Fig. 3B, C View Figure 3 ).

Description.

See Marusik and Koponen (2009).

Distribution.

To date, this species is known from Wrangel Island only ( Khruleva et al. 2022). Yet, the records of D. hyperboreus from Chukotka Peninsula ( Marusik 1993) are likely to also refer to D. wrangelianus . There are also unpublished data (YM, personal data) about its occurrence in Chaun Bay in Chukotka. Unfortunately, the sample studied, represented by females, was lost.
