Male 
Length about 6.0 mm; wing length about 4.5 mm. 
Relative head measurements (Figure 19): width 9.0; 
length 8.0; clypeal length 2.0; lower interocular 
distance 6.0; upper interocular distance 6.0; clypeo- 
antennal distance 0.2; interantennal distance 2.0; 
antennocular distance 1.4; interocellar distance 1.9; 
ocellocular distance 1.5. Anterior margin of clypeus 
gently convex; upper margin of clypeus not clear; 
facial foveae not evident; labial palps as in female; 
horizontal zone of propodeum longer than 
metanotum. Colour as in female, with labial palps 
with segment 1 dark brown, segment 2 brown, 
segments 3 and 4 yellowish. Terminalia as in 
Figures 30, 38 and 47. 
Remarks 
This is the only species in which the head of the 
female is not longer than wide. The head of the 
male is wider than long. The cup-like tip of the 
gonostylus of the genitalia (Figure 30) has not been 
seen elsewhere.
