BOMBUS MONGOLENSIS WILLIAMS SP. NOV.

(FIGS 10, 29, 72, 73, 101, 102)

[ Bombus (Subterraneobombus) tschitscherini Radoszkowski [cited as Behr]; Williams et al., 2009: 139 male only, misidentification.]

Note ( mongolensis). The usual neo-latin adjective for inhabitants of Mongolia is mongolicus (M. Alonso- Zarazaga, pers. comm.). This name is preoccupied by the senior homonyms: Bombus hortorum var. mongolicus Friese, 1916: 110 (? = B. diversus Smith); Lapidariobombus alagesianus ssp. mongolicus Skorikov, 1931: 226 (= B. keriensis Morawitz); and Bombus magnus Rasse mongolicus Krüger, 1954: 276 [not infrasubspecific after Tkalců, 1974b: 31; = B. lucorum (Linnaeus) complex]. Therefore, the name mongolensis is proposed (following previous usage of the neologism, e.g. Halictus rubicundus var. mongolensis Blüthgen, 1936) to convey the current knowledge of this species as an endemic of Mongolia.
