L’espèce se sépare facilement de Leucospis gigas Fabricius, 1793 dont la présence est peu probable en Belgique (Baur & Amiet, 2000 ; Boucek, 1959 et 1974 ; Schmid-Egger, 1995).

  • Ichneumon Sub-Families This Page Describes the Different Sub-Families of the Ichneumonidae
    Ichneumon Sub-families This page describes the different sub-families of the Ichneumonidae. Their ecology and life histories are summarised, with references to more detailed articles or books. Yorkshire species from each group can be found in the Yorkshire checklist. An asterix indicates that a foreign-language key has been translated into English. One method by which the caterpillars of moths and sawflies which are the hosts of these insects attempt to prevent parasitism is for them to hide under leaves during the day and emerge to feed at night. A number of ichneumonoids, spread through several subfamilies of both ichneumons and braconids, exploit this resource by hunting at night. Most ichneumonoids are blackish, which makes them less obvious to predators, but colour is not important in the dark and many of these nocturnal ones have lost the melanin that provides the dark colour, so they are pale orange. They have often developed the large-eyed, yellowish-orange appearance typical of these nocturnal hunters and individuals are often attracted to light. This key to British species is a draft: http://www.nhm.ac.uk/resources-rx/files/keys-for-nocturnal-workshop-reduced-109651.pdf Subfamily Pimplinae. The insects in this subfamily are all elongate and range from robust, heavily- sculptured ichneumons to slender, smooth-bodied ones. Many of them have the 'normal' parasitoid life-cycle (eggs laid in or on the host larvae, feeding on the hosts' fat bodies until they are full- grown and then killing and consuming the hosts) but there are also some variations within this subfamily.

  • Appendix S4. the Tentorium and Its External Landmarks in the Chalcididae
    Appendix S4 . The tentorium and its external landmarks in the Chalcididae This study is the first in the whole superfamily Chalcidoidea to investigate the tentorium as a phylogenetic character and to establish the connection between the inner skeleton of the cephalic capsule and its external landmarks on the back of the head. In this section, details are provided on the methodology used by GD to examine and code the different bridges. S4.1. Context Phylogenetic informativeness of the characters of the head capsule in Hymenoptera was recently highlighted (Vilhelmsen 2011; Burks & Heraty 2015; Zimmermann & Vilhelmsen 2016). However, interpretation is difficult and requires landmarks (Burks & Heraty, 2015). More precisely, the identity of the sclerotized structures between the occipital foramen and the oral fossa are still debated. Homology and nomenclature of these structures were established by Snodgrass (1928, 1942 and 1960) and reassessed by Vilhelmsen (1999) and Burks & Heraty (2015). These authors describe various types of ‘bridges’, such as postgenal, hypostomal and subforaminal bridges, according to the cephalic part – postgena or hypostoma – from which they putatively originate. In his phylogenetic analyses of the Chalcididae, Wijesekara (1997a & 1997b) used the back of the head – reduced to a single character – and distinguished an ‘hypostomal bridge’ and a ‘genal bridge’. The detailed examination of the back of the head in the Eurytomidae (Lotfalizadeh et al. 2007), probable sister group of the Chalcididae, provided useful characters for their phylogeny and prompted GD to also investigate these characters in the Chalcididae. Chalcididae exhibit variable and puzzling structures that may be phylogenetically informative but request a thorough identification of homologies among the subfamilies and more largely with other families of Chalcidoidea.

    Pacific Insects 13 (1) : 123-139 15 June 1971 SOME EPHIALTINAE, XORIDINAE AND BANCHINAE OF THE PHILIPPINES (Hymenoptera : Ichneumonidae)1 By Setsuya Momoi2 Abstract: Descriptions of 10 new taxa of Ichneumonidae of the subfamilies Ephial- tinae, Xoridinae and Banchinae, together with notes on some other ichneumonflies from the Philippines, are given. The present article treats material from the Philippines collected by members of the B. P. Bishop Museum and of the Noona Dan Expedition (Petersen, 1966). It includes descrip­ tions of some new taxa, viz., 1 species of Leptopimpla, 2 species of Itoplectis, 2 species of Coccygomimus, 2 species of Syzeuctus, and 2 species and one subspecies of Leptobatopsis, and notes on some other species. Most of the specimens treated in this paper, includ­ ing type specimens of the new species and subspecies described herein, are housed in the B. P. Bishop Museum (BISHOP) and the Zoological Museum of Copenhagen (COPEN­ HAGEN). Some duplicate specimens are retained in my collection at Kobe University. I am grateful to Dr J. L. Gressitt and Dr C.
