Holotype 
2, 26 miles (41.6 km) SSE of Wiluna, Western 
Australia, 1 September 1971, T.F. Houston, on blue 
E remophila (WAM). 
Para types 
Australia: Western Australia: 32, same data as 
holotype (WAM, UQIC). 
Description 
Female 
Length about 6.0 mm; wing length about 4.0 
mm. Relative head measurements: width 7.5; 
length 9.5; clypeal length 2.4; lower interocular 
distance 4.5; upper interocular distance 5.2; 
clypeo-antennal distance 0.4; interantennal 
distance 1.5; antennocular distance 1.1; 
interocellar distance 1.9; ocellocular distance 1.4. 
Anterior margin of clypeus slightly indented, 
upper margin of clypeus concave; malar space 
very short; frons above antennae with close 
reticulation and sparse punctures; foveae of 
second tergum of gaster about 3/5 as wide as 
long; labial palp segments in increasing lengths 1 
= 2, 3, 4 with segments 1 and 2 dark brown, 
segment 3 and basal 2/3 of 4 ribbon-like and 
yellowish; clypeus shining; supraclypeal area 
shining, concave. Legs mostly dark brown with 
tarsi golden. 
Remarks 
This species is very similar to E. yellowdinensis 
except in size. Until males are discovered, their 
relationship remains uncertain. 
Etymology 
The specific name refers to the type locality.
