The following description relates to all Euhesma 
known to be associated with Eremophila. 
Description 
Medium sized (length 4-7 mm) Euhesma with 
head, thorax and propodeum black. Gaster in 
most dark brown with tergal margins 
transparent; head longer than wide and 
narrower than thorax; facial foveae wide, 
shallow, impressed (Figure 17), upper part 
broadened and often curved towards ocelli, 
reaching level of antennal sclerites; eyes 
converging below; antennae inserted below 
middle of face with pedicel as long as first two 
flagellar segments together, all flagellar 
segments except last wider than long (females), 
interantennal distance greater than 
antennocular distance; labial palps as long as or 
longer than maxillary palps; anterior margin of 
clypeus broadly truncate; face in profile nearly 
flat with genal areas anteriorly very narrow 
(Figure 8 ); fore tibia with conspicuous apical 
spine (Figure 9); female with inner hind tibial 
spur pectinate (Figure 10) and in spite of view 
shown in Figure 10 , outer hind tibial spur 
strongly curved and shorter, thicker and 
heavier than inner hind tibial spur; basitibial 
plate indicated by carina (1 or 2 ) and tubercles 
with last tubercle half way or less along hind 
tibia (Figure 11 ), both plate and tubercles much 
stronger in female; tarsal claws with inner tooth 
(female) (Figure 12), bifid (male); foveae of 
second gastral tergum large, about as wide as 
long, diffuse, often difficult to see on dark 
background; wings evenly and closely covered 
with macrotrichia; forewing of most with first 
recurrent vein distal to first transverse cubital; 
body minutely roughened with face above 
antennae (Figure 13) and dorsum of thorax 
H.M. Exley 
consequently dull in most; scattered long white 
hairs on clypeus, frons, vertex, posterior genae,
