B.
himalayanus male mate-searching.
|
Mendacibombus
ecology
and behaviour
HABITAT:
High alpine grassland and mountain meadows.
FOOD-PLANTS: Medium
tongue-length bumblebees visiting medium-depth
flowers.
NESTING
BEHAVIOUR:
Nests underground. Larvae are reared in separate
cells throughout their development, non-pocket
makers. Food reserves are held in hexagonal wax
cells outside the brood-nest envelope (Haas, 1976).
MATE-SEARCHING
BEHAVIOUR:
Males have enlarged compound eyes relative to
the females. Six species studied perch (e.g. photo
left), race after potential mates, and may be
truly territorial (Williams, 1991
[pdf]).

Skorikov, 1914a:125,
type-species Bombus mendax Gerstaecker by subsequent
designation of Sandhouse, 1943:572
Bombus (Mendacibombus) Krüger, 1917:62
Part
of the bumblebee phylogenetic tree including available
Mendacibombus species from an analysis of DNA
sequence data for five genes (Cameron
et al. 2007
[pdf]).
Values above branches are Bayesian posterior probabilities,
values below branches are parsimony bootstrap values.
Williams et al. (2016)
revised all of the species with a complete tree based
on four genes.

STATUS: Although ostensibly described from Mongolia
(probably a mislabelling), this species is endemic to
a few of the higher parts of the Tibetan plateau.

TAXONOMIC
STATUS: Skorikov's (1910a)
descriptions of varieties of B. mendax are all
of females. Many of these nominal taxa have subsequently
been treated as separate species (e.g. Skorikov, 1931;
Rasmont, 1988).
The
females of the white-banded taxon altaicus and
the yellow-banded taxon margreiteri differ from
one another in colour, and the males have closely similar
genitalia.
Evidence from comparisons of DNA sequences is consistent
with the two taxa being conspecific (Williams et al.,
2016).
DISTRIBUTION:
Palaearctic, Oriental Regions.

examined
3 names
TAXONOMIC
STATUS: The white-banded taxon handlirschianus
and the yellow-banded taxon shaposhnikovi differ
principally in female colour pattern. Some males associated
with the two taxa were believed to differ in morphology
(Skorikov, 1931; Williams,
1991 [pdf])
and consequently the taxa had been treated as separate
species. More recently mixed colonies have been found
(De Meulemeester et al., 2010).
Furthermore, evidence from comparisons of DNA sequences
is consistent with the two taxa being conspecific (Williams
et al., 2016).
