A single female of this species was taken at ^Yau, Bahr-Fjl-dhazal, in 1905. 
The original description is appended below : — 
“ Head, small, broader than the thorax. Face, reddish, covered with grey tomentum 
and with short, scanty white pubescence ; beard, white. Palpi, yellow, thickly covered with 
black hairs, long and narrow, only slightly broader at the base, ending in an obtuse point. 
-Viitenna?, bright red, the extreme apex black ; the first joint short, broad, with a few l)laek 
hairs ; the second small, cap-shaped, with black hairs on its upper angle ; the third, with 
an obtuse tooth. Forehead, about four times as long as it is broad and the same width 
throughout, reddish with some little grey tomentum ; the callus shining red-brown, convex, 
oval, Ijecoming narrower at its lower end, whence proceeds a narrow, short, raised line, 
which widens to a spindle-shaped callus; from the vertex a narrow black line proceeds in 
two branches surrounding this last. Eyes with no markings. Thorax, reddish-brown, 
with traces of grey tomentum and of three stripes, the sides reddish with grey 
tomentum. Al)domen, narrow, reddish-brown, with a greyish-white median stripe 
reaching the fifth segment, the apex black, the segmentations very narrowly white, 
the pubescence on dorsum mostly black; underside testaceous with a black apex, in 
the other female it is very largely black. Legs, reddish, the femora (especially the fore 
femora) blackish, the fore tibiiB blackest at their apex, and fore tarsi black. Wings 
hyaline, the stigma yellowish, the veins yellowish brown (in the other female the fore 
border has a very slight tinge of yellow); the first posterior cell not narrowed.” 
The type from which this species was described came from Pungwe Valley, 
S.B. .\friea, in 1896.
