Dolda juveler – 33 nya arter av svenska glanssteklar (Hymenoptera: Chalcidoidea)

Abstract

Based on material collected with sweep nets, malaise traps and through rearing, the knowledge of the Swedish Chalcidoidea fauna is enhanced by new data on taxa occurring here, including new information on the biology for some of the species. Taxa reported as new to Sweden include one family (Neodiparidae), one genus (Neodipara Erdös) and 33 species in six families: Encyrtidae: Homalotylus platynaspidis Hoffer; Eulophidae: Apotetrastichus sericothorax (Szelényi), Aprostocetus eupatorii Kurdjumov, A. grandii (Domenichini), A. longulus (Erdös), A. ptarmicae Graham, A. tiliaceae Graham, Astichus solutus Förster,
Chrysocharis clarkae Yoshimoto, Diglyphus albiscapus Erdös, Entedon mecini Askew, Entedonomphale bicolorata (Ishii), Minotetrastichus platanellus (Mercet), Necremnus flagellaris Askew, N. hippia (Walker), N. tutae Ribes & Bernardo, Neotrichoporoides gordensis Graham, Omphale breviventris Graham, O. dolichura Hansson & Shevtsova, Pediobius deplanatus
Boucek, P. tenuicornis Graham, Platyplectrus chlorocephalus (Nees); Eupelmidae: Eusandalum inerme (Ratzeburg); Neodiparidae: Neodipara masneri Boucek; Pteromalidae: Colotrechnus viridis (Masi), Mesopolobus lichtensteini (Mayr), Psilocera confusa Graham, P. grahami Özdikmen, Sphegigaster stepicola Boucek: Torymidae: Diomorus calcaratus (Nees), Torymus filipendulae Graham & Gijswijt, T. persicariae Mayr, T. stenus Graham. Males are reported for the first time for Aprostocetus tiliaceae, Pediobius tenuicornis and Mesopolobus lichtensteini. The Swedish records for Neotrichoporoides biogradensis Graham
and N. viridimaculatus (Fullaway) are based on misidentified specimens, and these species should therefore be excluded from the Swedish list of chalcids. Further, we also mention and illustrate seven additional Eulophidae species which were recently reported new to Sweden in a separate publication. New host records include Didymomyia tiliacea (Bremi) (Diptera: Cecidomyiidae) for Mesopolobus lichtensteini. The species Erdoesia tessellata Boucek is also mentioned here because it has not yet been included in the official Swedish list of chalcids, even though a Swedish record has been published.
