The taxonomic placement of an enigmatic species of wasp known from two specimens in Late Cretaceous New Jersey amber is investigated through cladistic analyses of 90 morphological characters for 33 terminals ranging across non-Aculeata, non-Chrysidoidea, most subfamilies of Chrysidoidea and all genera of Plumariidae (the family to which the fossils were initially assigned), based on use of exem...

A review of the genera and species of Hymenoptera Parasitica and Chrysidoidea reported so far from Reunion Island is provided with host information. Data presented here is based on a review of the existing literature by the authors. The list includes: (1) 156 species of Ichneumonoidea belonging to 65 genera and 25 subfamilies (Braconidae: Agathidinae, Alysiinae, Aphidiinae, Braconinae, Charmont...

BACKGROUND The checklist of British and Irish aculeate Hymenoptera (Apoidea, Chrysidoidea and Vespoidea) is revised. Species distribution is summarised for all species at the level of country (England, Scotland, Wales, Ireland and Isle of Man). NEW INFORMATION The 601 native species represent an increase of 25 on the 1978 checklist, comprising mostly new discoveries. This increase is nearly b...

The mature larva of Ampulicomorpha schajovskoyi De Santis & Vidal Sarmiento, 1977, is described and figured for the first time. Larval characters of Dryinidae and Embolemidae are discussed in regard to possible synapomorphies of each family and of both families together (Dryinidae + Embolemidae) as monophyletic groups. Some larval characters are compared with the corresponding conditions in oth...

Some authors in the past based their conclusions about the limits of the metapostnotum of Chrysidoidea based on the position of the mesophragmo-metaphragmal muscle, rather than aspects of the skeleton and musculature associated with the metapectal-propodeal complex. The latter character system suggests another interpretation of the metapostnotum delimitation. Given this scenario, the main goal ...

This contribution presents the study of species-group of Plumarius Philippi 1873, as the result of a survey of the morphological variation in males. The group is characterized by the large ocelli and transverse head. It consists of the following three new species: P. culminatus Diez, Fidalgo & Roig-Alsina, sp. nov., P. ocellatus Diez, Fidalgo & Roig-Alsina, sp. nov., and P. stangei Diez, Fidalg...

An updated revision of Neotropical Dryinidae is presented. Seven subfamilies, 23 genera and 502 species are treated. Descriptions, geographic distribution, known hosts, natural enemies and type material of each species are presented, together with illustrations of the main morphological characters and keys to the subfamilies, genera and species. Complete lists of references concerning the Neotr...

Preliminary checklist of Bethylidae from France (Hymenoptera: Chrysidoidea). - A synonymic list French species is proposed based on a bibliographical synthesis, to which six new for the country are added by author, bringing number known 76. Within this list, genus Plastanoxus, deserving further investigation, Europe and possibly science. The conditions observing that specified comments made whe...
