Description
Male
MEASUREMENTS. Body length
11 mm
(
Fig. 29
).
HEAD. Dark, slightly as wide as long. Clypeus flattened, densely punctate, punctures separated by 0.5 puncture diameters, underlying surface shiny, without microsculpture. Gena, face, vertex, and scape covered with long whitish hairs that equal or exceed scape in length. Antennae dark, A4–13 slightly lightened grey below, A3 1.15 times as long as A4 (
Fig. 31
).
MESOSOMA. Scutum shagreened and dull over majority of disc, becoming weaker centrally and posteriorly, here weakly shining, surface densely but shallowly punctured, punctures apically separated by 0.5 puncture diameters, centrally becoming sparser, here separated by 1–2 puncture diameters. Scutellum more uniformly shiny and densely punctate, punctures separated by 1 puncture diameter. Episternum and propodeum weakly reticulate, underlying surface weakly shining, propodeal triangle basally comparatively more strongly reticulate, this dispersing apically. All parts of mesosoma with long brownish (scutum and scutellum) to whitish (episternum and propodeum) hairs that exceed length of scape. Legs dark, apex of hind tibiae and entirety of hind basitarsi orange, pubescence whitish. Wings hyaline, venation orange, nervulus interstitial. METASOMA. Terga dark, apical margins impressed, strongly impressed on T3–5, covered in short, thick, and complete white hair bands (
Fig. 33
). Terga densely punctate, punctures separated by 0.5–1 puncture diameters, underlying surface shagreened and dull basally, becoming weaker apically, T4–5 weakly shining. S8 columnar, parallel sided, apically slightly notched. Genitalia simple, gonocoxa with internal margins diverging apically, laterally with weak shagreenation, apical corners rounded (
Fig. 35
). Penis valve relatively narrow, apically tapering, gonostyli with broad bases, apical blades clearly longer than wide.

Remarks
In his original description,
Benoist (1961)
drew a comparison between
A. beaumonti
stat. rev.
and
Andrena flavipes
Panzer, 1799
, presumably because of the dense hair bands that help characterise this species.
Warncke (1967)
noted that this association was clearly incorrect at a subgeneric level, associating the bee with members of the subgenus
Taeniandrena
instead. On the basis of its large and dense puncturing, its golden hairs flanking the pygidial plate, and the orange metatarsi of the second pair of legs,
Warncke (1967)
associated this taxon with
Andrena wilkella
, but as a subspecies because of the unbroken hair bands on T3+4. He then went on to report
A. wilkella beaumonti
from
Iberia
(
Warncke 1976
; see also
Ortiz-Sánchez 2011
,
2020
), giving it a distribution of
Morocco
,
Spain
, and
Portugal
(see also
Lhomme
et al
. 2020
). However, genetic barcoding shows that
A. beaumonti
is distinct, and Moroccan material is also morphologically different from Warncke’s concept of
A. wilkella beaumonti
in
Iberia
, most obviously by lacking a shiny spot on the scutum that is well differentiated from the surrounding shagreenation. It can also be separated by the finer hairs on the scutum, the generally paler pubescence, and by the thicker and more complete hair bands on terga 2–4 (
Figs 20–27
), meaning that
A. wilkella beaumonti
sensu Warncke
in
Iberia
is actually undescribed (see below). The previously undescribed male of
A. beaumonti
can also be distinguished using the same characters (colour of pubescence, nature of tergal hair bands) and also by the length of A4 which is 1.15 times as long as A3, whereas in
A. benoisti
Wood & Praz
sp. nov.
(see below) it is 1.3 times longer (
Figs 30–31
). There are also slight differences in the genitalia, with a comparatively narrower penis valve and more clearly separated gonocoxa (
Figs 34–35
) in
A. beaumonti
.
Distribution
Morocco
, from the High Atlas Mountains in the area south of Marrakesh. The village of Asni is found at a moderate elevation of
1200 m
. It is not clear exactly where Arroud is because of changes in spelling practices, but it probably refers to the village Aroumd some
25 km
SSE of Asni. Contemporary sampling locations of
A. beaumonti
stat. rev.
are relatively close to Asni itself. Tizi-n-Test is some
60 km
SW of Asni, and Oukaimeden is even closer, just
10 km
to the SE. The site of Oukaimeden is at a much higher elevation of
3200 m
, and the cluster of records in this region suggests that
A. beaumonti
is restricted to high-elevation sites flying in May and June.
