striate .—Face with small area of dense, white pubescence 
in paraocular area to just above antennal sockets; vertex and 
frons with close, stiff, pale orange setae; clypeus with close, 
fine simple hair; scutum and scutellum closely covered 
with short, densely-branched, cream hair, becoming dense 
around margins; metanotum with slightly longer hair near 
tubercle; hind tibial scopa white; hind basitarsus with open 
fringe of long white plumose hair on posterior margin; 
metasomal T1 with dense white hair apicolaterally, T2-4 
with close white hair bands basally and broad, dense white 
hair bands apically, interrupted medially on T2; prepygidial 
fimbria white; S5 with dense, white apical fringe. 
Remarks. The sexes were associated by the protruding 
vertex and coincident collection. 
Etymology. The specific name is a Latin noun in apposition 
meaning hump, referring to the vertex of the female. 
Leioproctus (Protomorpha) gurneyi Batley n.sp.

straight spurs.
