Holotype 
2, 35 km E of Norseman, Western Australia, 
32°12'S 122°04'E, 30 October 1989, K.L. Walker on 
Eremophila (MV). 
Paratypes 
Australia: Western Australia: 1$, 3d same data 
as holotype (MV). 
Description 
Female 
Length about 5.0 mm; wing length about 4.0 
mm. Relative head measurements: width 6.3; 
length 7.1; clypeal length 1.9; lower interocular 
distance 3.7; upper interocular distance 4.3; 
interantennal distance 1.3; antennocular distance 
0.7; interocellar distance 1.5; ocellocular distance 
1.2. Clypeus with anterior margin indented 
medianly, upper margin slightly concave, 
dorsum shining with median longitudinal 
furrow; labial palps with segments in increasing 
lengths in the order 2, 1 = 3, 4. Labial palp 
segment one dark brown, others yellowish; legs 
dark brown with tibiae and tarsi mostly golden; 
dorsal surface of gaster golden brown with wide 
bands across segments 1-3 dark brown; venter 
light brown. 
Forewing with first recurrent vein distal to first 
transverse cubital. 
Male 
Length about 4.0 mm; wing length about 3.0 
mm. Relative head measurement: width 5.5; 
length 5.6; clypeal length 1.2; lower interocular 
distance 2.9; upper interocular distance 4.1; 
interantennal distance 0.9; antennocular distance 
0.7; interocellar distance 1.4; ocellocular distance 
1.1; ocelloccipital distance 0.1. Clypeus as in 2; 
labial palps with segments in increasing lengths in 
the order 2, 3, 1, 4. 
Labial palp segments 1, 2 dark brown, 3, 4 
yellowish; legs dark brown with fore tibiae and all 
tarsi light brown. 
Forewing with first recurrent vein interstitial 
with first cubital. Long white hairs on head, 
especially on clypeus. 
Remarks 
The males described are very much smaller than 
others in this group. They differ from the females 
in that colour is black predominantly and the first 
recurrent vein of the forewing is interstitial with 
the first cubital. 
Etymology 
The specific name refers to the golden brown 
colour on the gaster and legs of the female.
