Masner, a new genus of Ceraphronidae (Hymenoptera, Ceraphronoidea) described using controlled vocabularies
By Miko I, Deans AR
ZooKeys 20:127-153, 2009
PDF available at ResearchGate

Although the genus described is not found in the Nearctic, the paper is interesting for a few reasons:
• the new genus has characteristics of both Megaspilidae and Ceraphronidae, challenging "previous definitions of the two extant ceraphronoid families"
• the definition and use of a controlled vocabulary to describe character states (a benefit of which would be to avoid every entomologist using their own favorite terms, among others)

Flowering Plant Hosts of Adult Hymenopteran Parasitoids of Central Illinois
By Tooker, J.F. and L.M. Hanks
Annals of the Entomological Society of America, 2000
A large comprehensive study involving 151 parasitoid species over several parasitoid families and records covering over 33 years of observation and over 15,000 insect visitors. Provides persuasive data that Apiaceae (the carrot family) is the plant family by far most widely used by parasitoid wasp adults for feeding.
