Diagnosis

The species differs from congeners mainly by the configuration of the central edge of the gonopod telopodite apex, which is smooth (rarely) or with one to numerous small outgrowths (Figs 10B, 11B – several outgrowths) (vs without outgrowths in L. laqueatus, L. montanus, L. takakuwai), the gonopod telopodite with a low subapical not knee-shaped outgrowth (K1) (Fig. 10D) (vs without the outgrowth in other congeners excluding L. nakhodka sp. nov. and L. circularis; with K in L. nakhodka sp. nov.; not knee-shaped in L. circularis) and with a curved SL (Fig. 10B) positioned laterally (vs straight in other congeners excluding L. circularis; positioned mesad in L. circularis).

Remarks

Originally described from the environs of Vladivostok, Primorskiy krai, Russia (Attems, 1898), this species is common and abundant in the western and central parts of the Primorskiy krai (Mikhaljova 2017). The dorsum is often distinctively patterned (Fig. 12A–B). Its abundance ranges from 24 to 86.5 ind./m 2 in montane forests (the maximum abundance recorded is 172.5 ind./m 2), but this species is not numerous (4 ind./m 2) in floodplain forests (Mikhaljova 1988). Vulva as in Fig. 10E.
