 Dear Taxacomers:
The following message was also posted to PARAHYM and I appologize
for the cross posting, but I am trying to reach curators of museums that
are not hymenopterists, aphid workers, etc.  Thanks. I appreciate your

I am looking for a loan of any specimens of the genus Asaphes Walker
(Hymenoptera: Chalcidoidea: Pteromalidae: Asaphinae) from North
America that you may have in your collections.  I and Veli Vikberg are
completing a revision of this genus from North America and we want to
make sure that we have all available host and distribution records. Based
on material from borrowed collections to date there are six species of
Asaphes in North America, of which two are new. As you may know,
species of Asaphes are generally considered to be hyperparasites of
aphids, but one of the new species has definitely been reared as a
parasite (hyperparasite?) of the spruce budworm and balsam fir sawfly.
Consequently, I am particularly interested in any anomalous host records.
Please contact me directly about any specimens you may have. Thanks.
