Distribution
This subspecies inhabits the Arabian Peninsula (
Oman
,
UAE
) and is distinguished mainly by red terga (
Figs 13–14
). Also conspicuous are the zones of snow white, felted, adpressed pubescence on the face, particularly on frontal area and pronotum, and white, felted, upstanding hairs on the mesopleura, particularly the front as well as the posterior propodeal surface and the lateral fields above. This pubescence marks the subspecies as a desert form (
Ebmer 2008: 560
;
Dathe 2009: 385
). Specimens from
Oman
and
UAE
have red terga, whereas those from
Yemen
, identified as
L. villosulum
by Ebmer (D. Notton, unpublished new record), have dark black terga. Maybe there is more taxonomic complexity here, but it is outside the scope of the current project to further examine this. It may correlate with topography and climate since
Oman
and
UAE
are generally lower altitude (hotter) and
Yemen
is generally higher altitude (cooler).
