REVISION OF THE GENUSEUDERUSOF AMERICA NORTH OF MEXICO (HYMENOPTERA: EULOPHIDAE)

Abstract

The genus Euderus Haliday in America north of Mexico consists of five subgenera, Secodelloidea Girault, Euderus Haliday, Euderoides n. subgen., Neoeuderus n. subgen., and Leipocrossus n. subgen. and 25 species; 13 species are described as new and are as follows: Euderus (Secodelloidea) canadensis, E. (Euderoides) purpureus, E. (Neoeuderus) viridilineatus, E. (Neoeuderus) magnificus, E. (Leipocrossus) californicus, E. (Euderus) solidaginis, E. (Euderus) vockerothi, E. (Euderus) chillcotti, E. (Euderus) masoni, E. (Euderus) fuscedinellae, E. (Euderus) pecki, E. (Euderus) glaucus, and E. (Euderus) alaskensis. Species groups of albitarsis and solidaginis form two natural groupings within the genus Euderus s. str. Keys to subgenera and species, distribution, and host records are included.

Description of a new species of Euderus Haliday from the southeastern United States (Hymenoptera, Chalcidoidea, Eulophidae): the crypt-keeper wasp

“…The genus Euderus Haliday, 1844 is a group of parasitic wasps in the family Eulophidae (Hymenoptera) with approximately 77 described species (Yoshimoto 1971, Noyes 2016). The genus has a cosmopolitan distribution, where it is found in North and South America, Europe, Asia, Australia, and many isolated island archipelagos, including the Hawaiian islands, Micronesia, the Canary Islands, and the Seychelles archipelago (Ahmad 1976, Askew et al 2001, Báez and Askew 1999, Gates et al 2002, Gibson et al 2006, Goolsby et al 2001, Gunasena and Harris 1998, Herting 1973, Thompson 1955, Yoshimoto 1971).…”

“…Yoshimoto (1971) produced the last revision of the genus Euderus for North America, north of Mexico. The revisions built off of Nearctic catalogues by Peck (1951, 1963) and Burks (1967), with new additions based on material deposited in the Canadian National Collection, material loaned from the Natural History Museum, London, Philadelphia Academy of Sciences, and the Museum of Comparative Zoology, Harvard University.…”

Based on this revision, there are 22 species reported from North America north of Mexico, with 12 residing in the coastal southeastern U.S. (Florida, Alabama, Mississippi, Louisiana, and Texas; Yoshimoto 1971, Noyes 2016). According to Yoshimoto (1971), the biological records of Euderus from the U.S. indicate that most species are host specific on pupae of leaf tying, leaf mining, twig and fruit boring Lepidoptera (Tortricidae or Gelechiidae) and stem boring and other herbivorous Coleoptera (Buprestidae, Cerambycidae, and Curculionidae).…”

Rarely, Euderus has been reported to attack gall-making Hymenoptera (Cynipidae) or exhibit hyperparasitism on other Hymenopteran parasitoids (Ichneumonidae).…”
