description
Our PTP analysis (Fig. 10) of coalescents in the COI gene within the keriensis - complex supports six species including B. incertoides, corroborated by differences in morphology. These species are also supported by the absence of a positive divergence-with-distance relationship among them (Fig. 20) (see Divergence and geographical distance, page 12). From morphology, B. incertoides has enlarged male eyes and has a bright white banding pattern in the hair with (most strongly for the keriensis - complex) the thoracic dorsum with the posterior white band particularly narrowed by black hair anteriorly on the scutellum. Bombus incertoides can co-occur locally with the closely similar (but locally yellow-banded) B. separandus, at least in the Altai mountains of Mongolia.
description
Queens medium-sized body length 18 – 21 mm, workers 10 – 12 mm. Can be distinguished within Mongolia by the hair of the face black, the pale hair anteriorly on the thoracic dorsum pure white, the hair on the side of the thorax in its lower half black, the anterior half of the scutellum black, and by the hair of T 4 – 5 red (cf. B. sichelii, B. separandus). Males Body length 12 – 15 mm. Can be distinguished within Mongolia by the hair of the face black. Genitalia (Fig. 201) heavily sclerotised and dark, with the gonostylus longer than broad, its inner basal projection reduced to a stub (cf. rufipes- group, festivus- group, rufofasciatus - group); volsella with the inner distal corner broadly produced but without a narrow hook (cf. rufipes- group, festivus- group, rufofasciatus - group); antenna short and eye slightly enlarged relative to female eye.
