Colpoclypeus Lucchese, 1941 comparative info return to: prev(cir 4) prev(eul 19) home
Clypeal margin sharply incised. Female with only 2 funicular segments, males with 3; flagellar segments unbranched in males. Notauli usually incomplete, but sometimes complete and ending in anterior half of axillae (seen in extralimital forms--Egyptian specimens), far anteriad of scutellar margin; scutellum without submedian grooves; metanotum large, strongly sculpted, dorsellum crenulate/multidentate. Propodeum with strong median carina and plicae. Compare with: Necremnus, Eulophus.

Biology: Parasitoids of leaf-mining Tortricids.

Comments: This genus is easily recognized by its sharply notched clypeal margin and the unique dorsellum. It may be closely related to Eulophus and Necremnus, but no definable apomorphy for such a grouping is known to me, other than reduction characters. It does not have the transverse facial groove of the Cirrospilini.

Comparative information: Colpoclypeus specimens are normally easily identified if the clypeal margin is visible. Beginners may have some difficulty determining what specimens are not Colpoclypeus when they are unable to see the clypeal margin of smaller Eulophines such as Diglyphus. No comparable genus has a similar dorsellum or propodeum, although certain Eulophines near Eulophus and Dicladocerus have a reticulate dorsellum. Colpoclypeus is also much stouter-bodied than most Cirrospilini, excluding some Diglyphus and Danuviella.
