Naamlijst van de Nederlandse bronswespen (Hymenoptera: Chalcidoidea)

Checklist of the chalcid wasps of the Netherlands (Hymenoptera: Chalcidoidea) A first list of Dutch Chalcidoidea was published by Snellen van Vollenhoven in Herklots (Snellen van Vollenhoven, 1858). This list contained 24 species of chalcids, partly synonyms of each other. In a new list (Snellen van Vollenhoven 1873), he mentioned 85 species. Since Vollenhoven’s time about 250 names have been added by several authors in shorter communications. Not all the old names can be verified, many of the specimens are lost either by mold or voracious insects. In the list here presented the names of lost specimens are omitted (table 4) except when it concerns newly described species, or when additional remarks give a high probability of correct identification. These are marked with a question mark, as are literature records for which material had not yet been seen, but is present elsewhere. In this list we record 1085 species of Chalcidoidea, 620 of which are recorded for the first time for the Netherlands (marked with an *). For the new species information on a maximum of three localities are given for future reference. In these records the Dutch collectors and provinces are abbreviated (see table 2 and 3, respectively). Species which are introduced by man into the Netherlands and are only able to survive in the human environment are marked with a +. The diversity of chalcid wasps is shown in the colour plates. Remarks on individual species: Aphelinus longicornis (synonym of A. annulipes): Ferrière (1962, 1965) calls the type locality of Mesidia longicornis Eccle and Ecle. This should be Ede (Gelderland). Aprostocetus diversus: Usually, the hosts of this variable species are Rhabdopohaga species on Salix. Mr. Alders (Arnhem) reared a series of females from Pontania galls, collected near Best (nb). Aprostocetus rhacius: According to Graham (1987) this species was reared from galls of Dasineura trifolii (F. Löw). Mr. Vlug reared a series of this species from flowergalls in a Galium species (presumably Geocrypta galii (Loew)). Aprostocetus tanaceticola: In 1987 Graham described females only. I found an apparently overlooked male originating from the series out of which the paratypes were chosen. The labels say: ‘Wessem, 10.viii.1971, H.J. Vlug, Plat. 46”, ‘/gall Rhopal., tanaceticola, coll. 22.vii.1971” In his key to Aprostocetus males (Graham 1987: 188-210) A. tanaceticola runs to couplet 39 where it stands between A. salictorum Graham and A. cecidomyiarum (Bouché): The antennal scape is 2.9 times longer than broad, the ventral plaque has 0.4 length of scape, the length of pedicellus plus flagellum is 1.9 times breadth of mesonotum. In this specimen the mesosoma is only 1.1 times longer than broad. The mid and hind tibiae are yellow, very slightly darkened in the middle. Aprostocetus zosimus: Mr. W. Nijveldt reared this species from Mayetiola holci on Holcus lanatus. Perilampus batavus (synonym of P. tristis): Overlooked by Noyes (2002) is Smits van Burgst (1918), where the species is described for the first time. Later he did it again (Smits van Burgst 1919a).
