Batley & Popic: five new Leioproctus (Protomorpha) bees 
45 
laterally densely punctate; metasomal terga polished and 
densely punctate except on posterior margins; sterna with 
punctures sparse basally becoming dense apically, pygidial 
plate striate .—Face with dense, adpressed, white pubescence 
covering a triangular part of paraocular area from bottom of 
eye to level of mid frons; vertex and upper frons laterally with 
stiff orange setae (Figs. 8,9); clypeus and frons medially with 
close, fine simple hair; scutum covered with short, densely- 
branched, erect, white hair, open anteriorly, close medially, 
dense around margins; scutellum with similar, pale brown 
hair; hind tibial scopa white, plumose; hind basitarsus with 
open fringe of long white plumose hair on posterior margin; 
metasomal Tl,2 with dense white hair apicolaterally, T3,4 
with broad, dense white apical hair bands, T2-4 basally with 
close white hair bands; prepygidial fimbria white; S5 with 
dense, white apical fringe. 
Remarks. The sexes were associated on the basis of the 
biggibous vertex. A male and female were collected within 
days from the same plant species in neighbouring locations. 
Etymology. The specific name is a Latin noun in apposition 
meaning broad brow.

Diagnosis 
Female with hair on clypeus and frons simple, pygidial plate 
striolate, fovea ca as wide as base of scape, but obscured by 
pubescence. Male hind femur with broad ventral projection 
of anterior face, inner hind tibial spur flattened and strongly 
recurved, outer spur short, 0.3 x as long as inner (Fig. 3), 
lower gena concave. 
Descriptions 
Male —Head width 2 mm, body length 6.9 mm. Relative 
measurements: HW 50, HL 48, UID 33, UFW 33, LID 24, 
HVO 4, WOC 19, OOD 8, IAD 8, AOD 7, SL 15, SW 4, 
FL 41 .—Inner orbits convergent ventrally; clypeus trans¬ 
versely convex; interantennal area raised; labrum strongly 
carinate, basal part convex with medial depression, apical 
part concave; lower gena concave; flagellum 0.8x times 
as long as head width; metanotum with distinct tubercle; 
propodeal triangle subhorizontal basally, vertical apically 
with a sharp change of slope but no carina. Hind femur 
swollen ventrally on anterior face (Fig. 17); hind tibia 
moderately broadened, maximum width 0.27x length, 
with 8 stiff, curved setae and two spurs, inner flattened and 
strongly recurved, outer only 0.3x as long as inner; hind 
basitarsus shallowly concave with short apical extension of 
anterior margin (Fig. 16), width 0.43x length. Metasomal 
T2,3 with postgradular area depressed; S6 with strong 
medial ridge; S7,8 and genitalia as in Figs. 33-35.— 
Integument black except flagellum mostly orange-brown, 
labrum and mandibles orange-brown, metasomal terga with 
posterior margins translucent brown, sterna dark brown, 
tarsi dull orange-brown .—Clypeus densely punctate; 
supraclypeal area polished and impunctate on upper half; 
frons densely punctate, fovea obscured by pubescence; 
scutum and scutellum polished, closely punctate; 
metanotum with fine contiguous punctures; propodeal 
triangle coarsely rugose basally, propodeum laterally with 
contiguous punctures; metasomal terga closely punctate 
except for wide impunctate apical margins .—Face below 
mid frons densely covered with adpressed, silver-white 
pubescence; vertex with open, long, erect, plumose, white 
hair; gena with open, white, plumose hair; scutum and 
scutellum openly covered with long, white, finely plumose 
hair; metasomal T1 with open, long, white hair on basal 
half, T2-6 basally with broad bands close white hair; S3,4 
with long, even fringes; S6 with relatively weak apical tuft. 
Female —Head width 2.4 mm, body length 7.3 mm. Relative 
measurements: HW 50, HL 47, UID 33, UFW 34, LID 27, 
HVO 3, WOC 18, OOD 8, IAD 8, AOD 9, SL 16, SW 3, 
FL 27 .—Inner orbits convergent ventrally; clypeus weakly 
convex; labrum strongly carinate, basally convex with oval 
medial depression, apically concave; flagellum ca !4 as long 
as head width; mandible narrow, with rounded outer ridge 
and subapical tooth; propodeum as for male. Hind basitibial 
plate strongly carinate; inner hind tibial spur gently curved 
with 9 strong, well-spaced teeth; pygidial plate with irregular 
striae .—Integument black except flagellum dorsally dark 
brown with 4 apical flagellomeres orange-brown, ventrally 
orange-brown, labrum and mandibles orange-brown, 
metasomal T1,2 brown on apical half, all terga with posterior 
margins translucent brown .—Clypeus and frons densely 
punctate with polished interspaces; fovea impressed, about 
as wide as base of scape, upper end curving towards lateral 
ocellus; scutum and scutellum polished, closely punctate; 
metanotum with fine contiguous punctures; propodeal 
triangle rugose basally; propodeum laterally polished with 
close, even punctures; metasomal terga closely punctate 
except in apical marginal areas; sterna with punctures 
sparse basally becoming dense apically, pygidial plate

areas extending almost to top of eye and across lower % 
of frons (Fig. 10); frons and clypeus with open to sparse 
simple hair; scutum and scutellum closely covered with 
short, densely-branched, white hair becoming dense around 
margins; metasomal Tl^l with dense white apical hair bands, 
interrupted medially on Tl,2; T2,3 with close, white, basal 
hair bands; prepygidial fimbria pale brown. 
Remarks. The sexes were associated by the shape of the 
clypeus and coincident collection. 
Etymology. The specific name is a Latin noun in apposition 
meaning snow, referring to the colour of the facial hair of 
the female.
