Chalcidoidea (Hymenoptera) are extremely diverse with more than 23,000 species described and over 500,000 species estimated to exist. This is the first comprehensive phylogenetic analysis of the superfamily based on a molecular analysis of 18S and 28S ribosomal gene regions for 19 families, 72 subfamilies, 343 genera and 649 species. The 56 outgroups are comprised of Ceraphronoidea and most pro...

Background A revised checklist of the British and Irish Chalcidoidea and Mymarommatoidea substantially updates the previous comprehensive checklist, dating from 1978. Country level data (i.e. occurrence in England, Scotland, Wales, Ireland and the Isle of Man) is reported where known. New information A total of 1754 British and Irish Chalcidoidea species represents a 22% increase on the number ...

The family Pteromalidae (Hymenoptera: Chalcidoidea) is reviewed with the goal of providing nomenclatural changes and morphological diagnoses in preparation for a new molecular phylogeny book on world fauna that will contain keys to identification. Most subfamilies some tribes are elevated level or transferred elsewhere superfamily. resulting classification compromise, aim preserving validity di...

The genus Zaommomentedon (Chalcidoidea: Eulophidae) is recorded for the first time from India. A new species Z. giraulti Jamali et Zeya, sp. n. described Andhra Pradesh,

Chalcidoidea (approximately 22,000 described species) is the most ecologically diverse superfamily of parasitic Hymenoptera and plays a major role in the biological control of insect pests. However, phylogenetic relationships both within and between chalcidoid families have been poorly understood, particularly for the large family Pteromalidae and relatives. Forty-two taxa, broadly representing...

Taxonomic study of Indian species the genus Entedon Dalman (Hymenoptera: Chalcidoidea: Eulophidae), with description two new

Dicopuslongipes (Subba Rao) (Hymenoptera: Chalcidoidea: Mymaridae) is recorded from India for the first time. New additional distribution records of Mymaridae from the southern Indian states of Tamil Nadu and Kerala are documented.

Four new brachypterous species of Encyrtidae (Hymenoptera: Chalcidoidea) are described. These are: Astymachus eximius Hayat, sp. nov., Ixodiphagus aethes Hayat, sp. nov., Monstranusia brachyptera Hayat, sp. nov., Ooencyrtus notialis Hayat, sp. nov.
