"This paperback revision will be especially helpful to specialists working among the forest of ill-defined and undescribed Ichneumonidae (the most speciose insect family). Luhman adopts a particularly modern presentation: a model for future ichneumonid revisions with good discussions of character analysis and phylogeny supporting his detailed diagnoses and thorough morphological descriptions." (Foster Purrington, Department of Entomology, Ohio State University, From Annuals of the Entomological Society of America, Vol. 84, no. 5).
