Chaetotaxy of legs 1-3 usually as follows: upper subcoxae - 1, 3, 3; lower subcoxae - 0, 3, 3; coxae - 3, 8, 8; trochanters - 6, 6, 6; femora - 13, 12, 11; tibiotarsi - 19, 19, 18 setae, respectively. Tibiotarsal setae A1 and A7 on all legs as long as 1.5-1.7 inner edge of unguis, clearly clavate. Unguis with a pair of lateral teeth and usually with a small tooth in upper third of inner edge. Anal spines short, usually curved and set on tiny cuticular papillae.

sp. nov. are 22.2-29.1% (mean 24.9%), which can be considered as an additional argument in favour of its specific status. Nevertheless, such a scant amount of primary data does not allow for any serious statements to be made, but a trend to the absence of parallelisms in molecular and morphological evolution can be traced quite clearly.

sp. nov. was collected in two neighbouring sites located on the northern shore of the Sea of Okhotsk, in the vicinity of Magadan. In this region, it was mainly found in various herbaceous meadows at some distance off the coastal line, where its abundance may be very high. Its occurrence in all other types of coastal plat associations in the study area was rather sporadic.
