Análise faunística das subfamílias de Ichneumonidae (Hymenoptera: Ichneumonoidae) em uma área de floresta na Amazônia Brasileira e considerações sobre alguns gêneros [PDF]

open access: yes, 2019
Ichneumonidae is one of the largest families of Hymenoptera, with an estimated 60,000 described species, of which 17,000 occur in the Neotropical Region. Despite their high diversity, studies of the group are scarce in the Amazon region.

Local species richness of parasitoid wasps (Ichneumonidae: Pimplinae) in Ugandan tropical forest [PDF]

open access: yes
It has been suggested that the highly species-rich Ichneumonidae family of parasitoid wasps has an anomalous latitudinal diversity gradient, peaking in species richness outside the tropics.

Ecology and biogeography of island parasitoid faunas

open access: yes, 2010
Islands constitute natural laboratories for the study of evolutionary and ecological processes due to their discrete and isolated nature. Island biotas tend to be species–poor and disharmonic compared to the mainland; typically, interspecific ...
