Annotated and illustrated world checklist of Microgastrinae parasitoid wasps (Hymenoptera, Braconidae

Abstract

• A checklist of world species of Microgastrinae parasitoid wasps (Hymenoptera: Braconidae) is provided. A total of 81 genera and 2,999 extant species are recognized as valid, including 36 nominal species that are currently considered as species inquirendae. Two genera are synonymized under Apanteles. Nine lectotypes are designated. A total of 318 new combinations, three new replacement names, three species name amendments, and seven species status revised are proposed. Additionally, three species names are treated as nomina dubia, and 52 species names are considered as unavailable names (including 14 as nomina nuda). A total of three extinct genera and 12 extinct species are also listed. Unlike in many previous treatments of the subfamily, tribal concepts are judged to be inadequate, so genera are listed alphabetically. Brief diagnoses of all Microgastrinae genera, as understood in this paper, are presented. Illustrations of all extant genera (at least one species per genus, usually more) are included to showcase morphological diversity. Primary types of Microgastrinae are deposited in 108 institutions worldwide, although 76% are concentrated in 17 collections. Localities of primary types, in 138 countries, are reported. Recorded species distributions are listed by biogeographical region and by country. Microgastrine wasps are recorded from all continents except Antarctica; specimens can be found in all major terrestrial ecosystems, from 82°N to 55°S, and from sea level up to at least 4,500 m a.s.l. The Oriental (46) and Neotropical (43) regions have the largest number of genera recorded, whereas the Palaearctic region (28) is the least diverse. Currently, the highest species richness is in the Palearctic region (827), due to more historical study there, followed by the Neotropical (768) and Oriental (752) regions, which are expected to be the most species rich. Based on ratios of Lepidoptera and Microgastrinae species from several areas, the actual world diversity of Microgastrinae is expected to be between 30,000–50,000 species; although these ratios were mostly based on data from temperate areas and thus must be treated with caution, the single tropical area included had a similar ratio to the temperate ones. Almost 45,000 specimens of Microgastrinae from 67 different genera (83% of microgastrine genera) have complete or partial DNA barcode sequences deposited in the Barcode of Life Data System; the DNA barcodes represent 3,545 putative species or Barcode Index Numbers (BINs), as estimated from the molecular data. Information on the number of sequences and BINs per genus are detailed in the checklist. Microgastrinae hosts are here considered to be restricted to Eulepidoptera, i.e., most of the Lepidoptera except for the four most basal superfamilies (Micropterigoidea, Eriocranioidea, Hepialoidea and Nepticuloidea), with all previous literature records of other insect orders and those primitive Lepidoptera lineages being considered incorrect. The following nomenclatural acts are proposed: 1) Two genera are synonymyzed under Apanteles: Cecidobracon Kieffer & Jörgensen, 1910, new synonym and Holcapanteles Cameron, 1905, new synonym; 2) Nine lectotype designations are made for Alphomelon disputabile (Ashmead, 1900), Alphomelon nigriceps (Ashmead, 1900), Cotesia salebrosa (Marshall, 1885), Diolcogaster xanthaspis (Ashmead, 1900), Dolichogenidea ononidis (Marshall, 1889), Glyptapanteles acraeae (Wilkinson, 1932), Glyptapanteles guyanensis (Cameron, 1911), Glyptapanteles militaris (Walsh, 1861), and Pseudapanteles annulicornis Ashmead, 1900; 3) Three new replacement names are a) Diolcogaster aurangabadensis Fernandez-Triana, replacing Diolcogaster indicus (Rao & Chalikwar, 1970) [nec Diolcogaster indicus (Wilkinson, 1927)], b) Dolichogenidea incystatae Fernandez-Triana, replacing Dolichogenidea lobesia Liu & Chen, 2019 [nec Dolichogenidea lobesia Fagan-Jeffries & Austin, 2019], and c) Microplitis vitobiasi Fernandez-Triana, replacing Microplitis variicolor Tobias, 1964 [nec Microplitis varicolor Viereck, 1917]; 4) Three names amended are Apanteles irenecarrilloae Fernandez-Triana, 2014, Cotesia ayerzai (Brèthes, 1920), and Cotesia riverai (Porter, 1916); 5) Seven species have their status revised: Cotesia arctica (Thomson, 1895), Cotesia okamotoi (Watanabe, 1921), Cotesia ukrainica (Tobias, 1986), Dolichogenidea appellator (Telenga, 1949), Dolichogenidea murinanae (Capek & Zwölfer, 1957), Hypomicrogaster acarnas Nixon, 1965, and Nyereria nigricoxis (Wilkinson, 1932); 6) New combinations are
