Epigyne and spermathecae ( Figs 22–23 View Figs 16–23 ). The CD narrow, slightly widening anteriorly (handle-shaped), its middle part with a saddle-like concave. The EA heart-shaped. The S ovoid. The ID as robust sack-like structures, visibly bent laterally.
Remarks: The structure of male and female copulatory organs of P. lanchowensis is somewhat similar to those of P. histrio , P. ablegminus and P. xerophilus . The male is easily recognisable by the proboscis-shaped PTA (Fig. 13) and by the thicker and stronger RTA (Fig. 14). The female differs in having the heart-shaped EA, the well-marked epigynal sutures ( Fig. 22 View Figs 16–23 ) and the thick, S-shaped spermathecae and SO ( Fig. 23 View Figs 16–23 ).
Habitat: Tuva and Buryatia: shrubby steppe, birch-poplar and pine forests (present data), larch forest ( DANILOV, 1995: sub P. alascensis ). Elevations: 40–1600 m a.s.l.
Distribution: The Siberio-Far Eastern subboreal range; known from Tomsk Region in the west to Maritime Territory in the east (present data). For collecting localities see Map 7 View Maps 7–8 .
This species was hitherto reported from Buryatia under the name P. alascensis ( DANILOV 1995, 1999). It is very likely that the undetermined Philodromus species reported from Japan by YAGINUMA (1986: fig. 11) and CHIKUNI (1989: 136, fig. 12) is actually P. lanchowensis . As we have been unable to re-examine any comparative material from Japan, the matter needs further attention in the future.
