Cirrospilus Westwood, 1832 comparative info return to: prev
Face with transverse groove at mid-height (can be difficult to discern). Vertex
usually not distinctly arched above upper eye margin (exceptions include C. coachellae
Gates). 2 funicular segments, 3 claval segments. Notauli complete and straight or
weakly curved, reaching scutellar margin or ending in axillae very near
scutellar margin; sidelobes with narrow scapular flange reaching or nearly reaching
scutellar margin; half or less of dorsal surface of axillae anteriad of scutellar margin;
scutellum flat, with parallel submedian grooves that may be difficult to discern. Postmarginal
vein equal to or shorter than stigmal vein length; stigma round,
with uncus about its own length from stigmal apex; forewing usually without fuscate
markings (many exceptions). Compare with: Aulogymnus, Diaulinopsis,
1a: Cirrospilus vittatus Walker color variants (dark markings
represent dark or metallic green color)
2a: Cirrospilus vittatus forewing
Biology: Primary or
secondary parasitoids leaf-miners, leaf-rollers, and gall-makers.
Comments: Very large
Aulogymnus: Uncus separated by more than its
own length from stigmal apex (typically much more), or rarely absent (check both wings,
because the character may vary in an individual or series). Stigma distinctly elongate.
Scutellar grooves, when distinguishable, very close together. Flagellum often with 3 or
more funicular segments. Body generally arched and stout (flattened in most Cirrospilus).
Some species are problematic because of a general similarity to Aulogymnus and a
medium-length stigma, and it is not clear at this time where these species should be
placed without host information.
Diaulinopsis: Postmarginal vein 2x stigmal
vein length or more. Males with greatly expanded scape. Color of dorsum uniform metallic
or dark except near wing base, while Cirrospilus are usually extensively yellow.
Zagrammosoma: Notauli incomplete or ending
in anterior half of axillae, the dorsal surface of which are advanced almost entirely
anteriad of scutellar margin. The notauli are very short and curve sharply towards the
axilla, where in Cirrospilus they are nearly straight, ending in the scutellar
margin or nearly so. Also, the scapular flange of each mesoscutal sidelobe in Cirrospilus
extends as a narrow projection to the scutellar border or near it, while in Zagrammosoma
the scapular flange is a very tiny extension ending near the axillar apex. Vertex
always extending high above upper eye margin (occurs in a few Cirrospilus as
well). Forewing always with fuscate markings.
Diglyphus: Notauli incomplete or ending in
anterior half of axillae, color usually almost entirely metallic or dark.
