Key to puparia of tachinid parasitoids of Nearctic
Choristoneura
species
1. Posterior spiracular discs borne on a cylindrical projection that is about as long as wide (
Fig. 36
) ......................................................................................
Actia interrupta
– Posterior end of puparium without such a projection (
Figs. 22–35
) ............................ 2
2. Slits of posterior spiracular discs broadened considerably (
Fig. 35
)
......
Actia diffidens
– Slits narrow (
Figs. 22–34
) ............................................................................................ 3
3. Each posterior spiracular disc with three slits (
Figs. 27–34
) ....................................... 4
– Each posterior spiracular disc with four slits (
Figs. 22–26
) ....................................... 12
4. Prominent bulge present below posterior spiracular discs, much broader and higher than a single disc (
Figs. 31, 33
) .................................................................................... 5
– Bulge below posterior spiracular discs absent or small, not higher or broader than a single disc (
Figs. 28–30, 32
) ........................................................................................ 7
5. Posterior spiracular discs scarcely raised above surface of puparium, with shallow grooves between spiracular slits; bulge below spiracular discs rarely extended dorsally to region between discs (
Fig. 33
)
...................................................
Smidtia fumiferanae
– Posterior spiracular discs protruding above surface of puparium, with deep grooves between spiracular slits; bulge below spiracular discs varied along dorsal edge (
Figs. 28, 31
) ......................................................................................................................... 6
