(Fig. 37); S7 with rectangular lateral lobes, large basal teeth 
and posterior projections (Fig. 45).— Labrum , mandible, 
scape, tarsi, tibiae and distal ends of femora orange-brown, 
fore and mid tibiae with darker areas medially; flagellum 
dark brown dorsally; F2-11 orange-brown ventrally. Tl-5 
with narrow silver bands stained feruginous across anterior 
margin.— Clypeus with dense, fine punctures except near 
ventral rim. Scutum with dull sheen, reticulate with close, 
small punctures.— Face with dense, pale orange, plumose 
hair; gena with very dense, plumose, white hair. Scutum

margin of hind tibia with open fringe of long, white hair. 
Female (AM K.344659).— Head width 4.20 mm, body 
length 12.0 mm. Relative dimensions: HW 50, HL 37, UID

13, OOD 4, IAD 8, ASD 3, AOD 8, ML 19, BMW 8, MSL 
1.0, SL 15, SW 3, FL c. 30.— Eyes hairy; face slightly 
broader than long, inner orbits gently convergent ventrally; 
length malar space c. O.lx basal mandibular width; clypeus 
shallowly convex, slightly flattened sagittally; gena 0.55x 
as wide as eye viewed laterally; flagellum short, middle 
flagellomeres approximately as wide as long; inner hind tibial 
spur with c. 11 strong teeth; tarsal claws simple; pygidial 
plate entire, flat.— Labrum , mandible, tarsi (except mid 
basitarsus), hind tibia, distal ends of femora orange-brown; 
remainder of legs dark brown. Tl-4 with narrow silver 
bands, weakly ferruginous across anterior margin.— Clypeus 
reticulate except along ventral margin, densely punctate. 
Scutal sculpture as for male.— Face with long, plumose hair, 
white in lower paraocular areas, becoming orange-brown 
tipped with dark brown near ocelli, dense in paraocular areas 
and on frons, open on clypeus and supraclypeal area; gena 
with close, plumose white hair. Scutum with close, plumose, 
dark-tipped pale orange hair; hind tibial scopa orange-brown 
laterally, darker medially; prepygidial fimbria dark brown. 
Etymology. The specific name, used as a noun in apposition, 
is from the Latin for white cheeks.
