LEPIDOPTERA

Boloria banghaasi Seitz, [1909]
Boloria banghaasi Seitz, [1909]

• TYPE LOCALITY. «Kentei» [Kentei Mts., ?Mongolia].

• RANGE. From the Altais to the coasts of the Sea of Okhotsk, E Yakutia, Kamchatka, Amur region and Sakhalin. The northern and eastern range limits require refinement.

• DISTRIBUTION AND VARIATION. Most of the distribution area is inhabited by the nominotypical subspecies. From the Magadan Region and Chukotka, the ssp. infans Churkin, 2000 has recently been described.

• TAXONOMIC NOTES. The status ofB. banghaasi remains unclear, as it might turn out to only represent a subspecies of B. aquilonaris (Stichel, 1908). The little-known taxon neopales (Nakahara, 1926) (= sachalmensis (Matsumura, 1925), nom. praeoccup.), described from Sakhalin, can prove to belong to this species (Warren, 1944). Populations from the Altais have just been described as the ssp. roddi Kosterin, 2000.

• HABITATS AND BIOLOGY. Swampy meadows and slopes, high bogs up to 2.500 m a. s.l. Flight period: July to August.

• SIMILAR SPECIES. Boloria alaskensis: HW with a distinct prominence with a top at vein M3. B. altaica: larger; black marking on UPS more delicate. B. frigidalis: black marking on UPS more delicate; ground colour of UNH dark, brick-red or brownish hue; UPS often with greyish dust. B. aquilonaris: on costal side, second black spot of postdiscal row of UPH (between veins M^ and M^) not larger than first and third ones.
