( Figs 130, 131 )

Bombus patagiatus Nylander, 1848:234 .

Bombus ikonnikovi var. ganjsuensis Skorikov, 1913:172 .

Taxonomy. Revised by Williams et al. (2012a, b). The white-tailed colour pattern of this species ( patagiatus s. str.) has been confused with B. lantschouensis and B. minshanensis . The orange-tailed colour pattern of this species (ganjsuensis) has been confused with B. hypocrita Pérez.

Material examined. 23 queens, 1241 workers, 722 males (IAB).

Distribution in North China. Widely distributed within the zone between the Neimenggu plateau and the Qinghai-Tibetan plateau and the Qinling mountains, as well as the Great Khingan mountains. Abundant at low to medium elevations of the Yanshan mountains in northern Beijing and northern Hebei, at low to medium elevations of the Bashang plateau in north Hebei, at low to medium elevations of the Great Khingan mountains in northeastern Neimenggu, at medium elevations of the Liupanshan mountains in southern Ningxia, and at medium elevations of the west Qinling mountains and the loess plateau in eastern Gansu. Common at medium elevations of the Taihangshan mountains and the Lvliangshan mountains in Shanxi, at medium elevations of the loess plateau in western Shaanxi, and at low elevations of the Nenjiang river valley mountains in northeastern Neimenggu. Rare at low elevations of the Mianshan mountains in central Shanxi, at low elevations of the northern edge of the Guanzhong plain in central Shaanxi, and at medium elevations of the edge of the east Qinghai-Tibetan plateau in Gansu. 187 localities ( Fig. 130 ) between 215–2872 m (IAB).

Variation in North China. This species shows strong variation in the colour pattern of the hair within North China (see the key; Williams et al., 2012b).

Similar species in North China. This species can be very similar in its white-banded female colour pattern to B. minshanensis (see the key; Figs 129 , 131 ).

Distribution in China. Beijing, Hebei, Shanxi, Neimenggu, Liaoning, Jilin, Heilongjiang, Shaanxi, Gansu, Qinghai, Ningxia (IAB).
