ABSTRACT:
Evarca falcata (Clerk, 1757) has been shown to actually represent a complex of three sibling species, all described and illustrated upon samples covering the entire Holarctic.
E. falcata s.str. actually occurs throughout Europe, reaching northern Kazakhstan, Xinjiang, China as well as West and South Siberia up to Cisbaikalia in the east.
E. hoyi (Peckham & Peckham, 1883) is a "good" species, purely Nearctic in distribution; its lectotype is designated, and
Habrocestum latens Banks, 1892 considered as another of its subjective junior synonyms, for the first time.
E. proszynskii sp.n. is described from the Far East of Russia, though its actual distribution covers also much of Siberia and a part of East Kazakhstan as well as China, Korea, Japan and much of western North America. Hence the ranges of these three species are largely allopatric, although only male-containing samples in the relatively few and minor zones of contact or overlapping (Tuva, Siberia for
E. falcata and
E. proszynskii and the central regions of the Nearctic for
E. proszynskii and
E. hoyi) can be identified securely to species.

This 1997 paper by Marusik and Logunov is a revision of the
Evarcha falcata species group within the Palearctic and Nearctic regions.
E. proszynskii is described for the first time. Descriptions are also provided for
E. falcata and
E. hoyi, and ranges are provided for all three species.
