Eyes setose. Occiput strongly concave, vertex carinate,
eye reaching posterior margin of head in dorsal half (all these characters as in Hoplocrepis).
Flagellar formula vaguely 1,3,3 or 1,4,2, described as 1,4,2 in males and 1,3,3 in females
(Schauff 2000); basal flagellomeres in males and females serrate to mildly
pedunculate. Pronotal collar relatively long and broader than anterior portion of
mesoscutum; notauli complete; mesoscutal midlobe with up to 3 pairs of
setae (taking care to include those near the notauli); sublateral scutellar
grooves present, concave laterally and converging
medially (this form not unique). Postmarginal vein subequal or slightly longer
than stigmal vein. Median carina of propodeum forked at nucha, forming
large areole enclosing nucha; plicae incomplete, projecting from anterior
corners of nuchal areole; carina present posterior to spiracle, patch
of setae usually present posterior to carina, usually separate from callar setae.
Petiole with dorsal and lateral flanges. Compare with: Elachertus,
1a-c: Deutereulophus mesosomatic dorsum (left), female antenna
(center), and male antenna (right)
2a-b: Deutereulophus propodeum, dorsal view (left), and lateral view
described species. Similar in many respects to some Elachertus, and may
eventually prove to be simply a distinctive species group of Elachertus, or, more
preferably, one of many genera retained after splitting Elachertus into
manageable monophyletic genera. I have seen several Nearctic, Oriental, and
Neotropical specimens that in one or more ways blur the distinction between these two
genera, especially in that they frequently have the group of setae posterior to the
propodeal spiracle joining the group on the propodeal callus, or lack these setae entirely
while possessing most other characters of Deutereulophus.
Elachertus: Mesoscutal midlobe with at least
the first two pairs near the center of the midlobe (all but one pair near the notauli and
scutellar border in Deutereulophus). Propodeum without special patch of setae
separate from callus setae. Some species of Elachertus have a similarly areolate
median propodeal carina and body form, but differ in the characters given here.
Hyssopus: Mesoscutal midlobe with 2 pairs of
setae, Median carina of propodeum not areolate. Propodeum without special patch of setae
separate from callus setae. Pronotum smoothly arched in profile, without differentiated
