Micaria yeniseica Marusik & Koponen, in Marusik et al. 2002: 345, figs 1-2 (♂).

Material.

11♀ 2♂ [Gor].

Description.

Female. Total length 3.15-3.75 mm, carapace 1.5-1.7 long, 1-1.1 wide, length/width ratio 1.5. Carapace dark brown with silver hairs. Legs dark brown. Leg lengths as in Table 1 View Table 1 . Abdomen silver black with two sublateral white spots at the top of abdomen, and whitish stripe in the middle of abdomen. Carapace/tibia I ratio 0.7, tibia I/metatarsus I ratio1.2. Epigyne as in Fig. 4A-D View Figure 4 .

Note.

The comparative figures of M. yeniseica and its sibling species M. silesiaca L. Koch, 1875 are provided here. The males of two species are easily distinguishable by the relative length of the tibia (longer in M. yeniseica ), the position of the tegular apophysis (antero-prolateral vs. central) and shape of the retrolateral part of the sperm duct (straight vs. rounded). No distinct differences have been found between the females of two species, in which the conformation of receptacles strongly varies.

This species is new to Kamchatka. Earlier, it was known from the type locality and only from the holotype male, from the middle reaches of Yenisei River ( Marusik et al. 2002; Mikhailov 2013). It seems that it has a disjunctive range as it is unknown between Yenisei and Kamchatka. This record extends the known range to about 70 º or 3800 km to the east and represents the easternmost limit of the species’ distribution.
