Relationships. This species belongs to the Imperialis species 
group of Trachysphyrus (Porter 1967: 275-6). It shows superficial 
affinity to T. escomeli (Brethes) and T. aglaus Porter. 
Trachysphyrus escomeli (Porter 1967: 319-20) is known only 
from Arequipa on the west Andean slopes of southern Peru and 
might be expected to overlap the range of T. agalma in similar 
habitats of adjacent north Chile. Females of the 2 species differ 
because T. agalma has the clypeus low in profile (moderately high 
and bluntly subpyramidal in T. escomeli ), the temple 0.7 as long as 
eye in dorsal view and sparsely punctate throughout (less than 0.5 as 
long as eye and becoming densely punctate above in T. escomeli ), 
the notauli impressed for about 0.3 the length of the mesoscutum 
(0.7-0. 8 the length of mesoscutum in T. escomeli ), the mesopleuron 
with some areas of coarse wrinkling (with moderately strong reticu- 
late wrinkling in T. escomeli ), the 2nd gastric tergite scarcely sha- 
greened (with fine micro-reticulation in T. escomeli ), and the dorsal 
ovipositor valve tapering directly from notch to apex (a little con- 
vexly tapered in T. escomeli). Brethes includes a male in his origi- 
nal diagnosis of T. escomeli (1919: 124), but that specimen now 
appears lost and the author’s account of it does not allow compari- 
son with males of related species. 
Trachysphyrus aglaus (Porter 1967: 285-86) was described from a 
single male taken in the west Andean region of central Peru. This 
species resembles T. agalma in its peculiarly shaped areolet and 
rather strong propodeal cristae, but differs by its shaggy temporal 
setae, long and overlapping 2nd gastric setae, and shorter temples. 
Field Notes. Specimens of T. agalma were obtained only by 
Malaise Trap, although much hand collecting was done at the type 
locality. The trap was set up across an irrigation ditch bordered by 
tall bunch grass, oregano fields, and Eucalyptus trees. 
Specific Name. From the Greek noun agalma , “glory, honor, 
delight.”
