Vertex arched high above eye level. 2 funicular segments. Notauli sharply
curved, ending in anterior half of strongly advanced axillae;
mesoscutal sidelobes with tiny scapular flange that does not extend more than 1/4 the
axillar length, ending far from the scutellar margin. scutellum with parallel submedian
grooves. Forewing always with fuscate areas. Propdoeum without plicae, with remnants of a
simple median carina. Color at least partly yellow. Compare with: Cirrospilus.

Comments: This genus
is generally considered dubiously distinct from Cirrospilus. If notaular form is
any indication of phylogeny (which may or may not be the case), it may be more closely
related to Diglyphus. However, the recent discovery of Cirrospilus coachellae
Gates, which has a vaulted vertex like all Zagrammosoma, is the best evidence for
a clade of Cirrospilus and Zagrammosoma, but raises the possibility of a
paraphyletic Cirrospilus. At any rate, lumping of Zagrammosoma into Cirrospilus
would be highly premature before extensive analysis is conducted.
Cirrospilus: Notauli extending as nearly
straight lines to end at or near the scutellar margin; mesoscutal sidelobes with narrow
scapular flange extending to or near the scutellar margin. Vertex seldom protruding above
upper eye margin (exceptions include C. coachellae Gates).
