Species-taxon concept and variation
The taxon concept of the species B. genalis here agrees with the long-standing interpretation (Williams 2022a) that it is separate from the taxon concepts of other species in the subgenus Alpigenobombus , based on: (1) our PTP analysis supports independent species-level coalescents in the COI gene ( Fig. 12 View Fig ); corroborated by (2) diagnostic morphological character states (see the keys).
The PTP and morphological results ( Fig. 12 View Fig , keys) support the interpretation that B. genalis and B. breviceps are separate species. The available COI-barcode-like sequences may all be low-divergence neonumts ( Fig. 11 View Fig ).
No substantial colour-pattern variation is known for B. genalis (Figs 74‒75). Bombus genalis , with its black with orange-legged colour pattern, appears to mimic the common B. (Pyrobombus) flavescens Smith, 1852 , and B. (Melanobombus) eximius Smith, 1852 ( Williams 2007: fig. 5a).
Type material
Bombus genalis Friese, 1918: 84 View in CoL . Syntypes: ♀♀ (queen and worker) Sikkim, India ( ZMHB). Examined .
Morphological diagnosis
Female
Wings pale yellow with the veins light orange (unique within the subgenus Alpigenobombus ), hair short, oculo-malar area shorter than broad, clypeus in its central area shining with only a few small and large widely-spaced punctures (cf. B. breviceps ); mid and hind tibiae exoskeleton and hair bright orange, hair of the thoracic dorsum and T1 black.
Male
Wings pale yellow with the veins light orange (unique within the subgenus Alpigenobombus ), hair short, oculo-malar area shorter than broad; genitalia ( Fig. 113 View Figs 106–115 ) with the gonostylus nearly equally short on both its outer side and its inner side but with the distal lobe projecting inwards as a long broadly triangular acutely pointed process, triangular in section (cf. B. breviceps , B. grahami ); mid and hind tibiae exoskeleton and hair bright orange, the hair of the scutellum and T1 predominantly black.

Global distribution
Himalaya and borders of southern Hengduan: India (Sikkim, Arunachal Pradesh), China (Xizang, Yunnan), Myanmar: IAR, IOZ, NCBS, NHMUK, PW, ZMHB.
This is an uncommon species and few individuals have been recorded. This species is recorded at elevations of 1561‒1852 m in the Himalaya in the middle forest zone ( Streinzer et al. 2019).
Behaviour
Male eye very slightly enlarged relative to female eye, male mate-searching behaviour unknown.
