| Summary: | Savignia zero (Eskov, 1988) (Fig. 9–20) Savignia zero Eskov, 1988: 34, figs 83–85 (D 3). HOLOTYPE: Russia: Magadan: middle Chelomdzha river (left tributary of Taui river), 13, vi.–viii. 1987 (N.E. Dokutchaev; not examined, due to the distinctive male carapace). Examined material. Russia: Magadan: Ola river mouth, 83 14 Ƥ, 18.ix. 1990 (Y.M. Marusik, SMF 39671). Khabarovsk province: environment of Bychikha village, Bolshekhektsyrski reserve, “Klyuch Sosnenskiy” kordon, circa 430 m, tall grass and carex along creek valley formed by boulders [48 º 14 ' 33 ''N, 134 º 47 '00''E], 73 13 Ƥ, 14.ix. 2005 (Y.M. Marusik, IBPN); environment of Khabarovsk, environment of Bychikha village, Bolshekhektsyrski reserve, secondary forest with birch and other trees, leaf litter and carex [48 º 17 ' 30 ''N, 134 º 49 ' 42 ''E], 13 1 Ƥ, 11.ix. 2005 (Y.M. Marusik, IBPN). Examined comparative material: S. birostra: USA: Alaska: Kodjak island, Dog Salmon river [57 ° 11 ' 49 ''N, 154 °02'08''W], 53 5 Ƥ (NMBE 6744). S. saitoi: Russia: Sakhalin: Sakhalin island, southeast port, Mereya river circa 3 km from mouth, [46 ° 38 ' 46.4 ''N, 142 ° 54 ' 16.1 ''E], 4 Ƥ, 28.vii. 2001 (Y.M. Marusik. IBPN). Sakhalin: Kunashir island, Otrandnoye, 13, 19.ix. 1987 (A.M. Basarukin, ZMMU). Six examined paratype females (Russia: Amur: Khingan state reserve, gramineous meadow, 2 Ƥ, 01.viii. 1983 (Y.M. Marusik, IBPN). Sakhalin: Kunashir island, Otrandnoye, 4 Ƥ, 19.ix. 1987, (A.M. Basarukin, ZMMU)) that were mentioned in Eskov (1988) are not conspecific with topotype females from Sakhalin and their belonging is unclear. Diagnosis. Males are best distinguished from other Savignia species by its arch-like PME-lobe and the frontally protruding AME-lobe, which both are covered with stout hairs frontally (Eskov 1988: fig. 83). Male cephalic lobes of all Savignia species are species specific (e.g. see figures in Eskov 1988). The embolic division and especially the margin of the transparent outgrowth is species specific but difficult to differentiate without comparative ... |
