Two new species of Oobius Trjapitzin (Hymenoptera, Encyrtidae) egg parasitoids of Agrilus spp. (Coleoptera, Buprestidae) from the USA, including a key and taxonomic notes on other congeneric Nearctic taxa.

ABSTRACT: Oobius Trjapitzin (Hymenoptera, Encyrtidae) species are egg parasitoids that are important for the biological control of some Buprestidae and Cerambycidae (Coleoptera). Two species, Oobiusagrili Zhang & Huang and Oobiuslongoi (Siscaro), were introduced into North America for classical biocontrol and have successfully established. Two new native North American species that parasitize eggs of Agrilus spp. (Buprestidae) are described and illustrated from the USA: Oobiusminusculus Triapitsyn & Petrice, sp. n. (Michigan), an egg parasitoid of both Agrilussubcinctus Gory on ash (Fraxinus spp.) and Agrilusegenus Gory on black locust (Robiniapseudoacacia L.) trees, and Oobiuswhiteorum Triapitsyn, sp. n. (Pennsylvania), an egg parasitoid of Agrilusanxius Gory on European white birch (Betulapendula Roth). A taxonomic key and notes on the Nearctic native and introduced Oobius species are also included.

Project description:The Agrilus occipitalis species-group is redefined and diagnosed. Two species from this group, Agrilus auriventris Saunders, 1873 and Agrilus occipitalis (Eschscholtz, 1822), are known as the serious pests of cultivated Citrus trees. Overall twenty-three taxa are included in the Agrilus occipitalis species-group. A complete list of references, type material, species examined and distribution is given for each taxon. The host plants, adult occurrence and altitude range is cited for most taxa. Habitus of all taxa and aedeagi of available males are pictured. Images of primary type specimens are provided. A character state matrix table for diagnostic characters is given for all taxa to facilitate their determination. The following new taxonomic and nomenclatural acts are proposed. New species:eight new species are described: Agrilus mucidus sp. n., Agrilus nebulosus sp. n., Agrilus picturatus sp. n., Agrilus pluvius sp. n., Agrilus pseudoambiguus sp. n., Agrilus tesselatus sp. n., Agrilus trepanatus sp. n. and Agrilus umrongso sp. n. Proposed synonyms: eight synonyms are proposed: celebicola Obenberger, 1924, syn. n. (synonym of occipitalis Eschscholtz, 1822); connexus Kerremans, 1900, syn. n. (synonym of occipitalis Eschscholtz, 1822); cupricauda Saunders, 1867 syn. n. (synonym of occipitalis Eschscholtz, 1822); evinadus Gory & Laporte, 1839, syn. n. (synonym of occipitalis Eschscholtz, 1822); nirius Obenberger, 1924 syn. reconfirmed (synonym of occipitalis Eschscholtz, 1822); oblatus Kerremans, 1900, syn. n. (synonym of occipitalis Eschscholtz, 1822); samoensis Blair, 1928, syn. n. (synonym of auriventris Saunders, 1873); tebinganus Obenberger, 1924, syn. n. (synonym of occipitalis Eschscholtz, 1822). New lectotype designations: six lectotypes are designated: Agrilus celebicola Obenberger, 1924; Agrilus cupricauda Saunders, 1867; Agrilus korenskyi Obenberger, 1923; Agrilus kurandae Obenberger, 1923; Agrilus nirius Obenberger, 1924; Agrilus nitidus Kerremans, 1898.

Project description:The genus Scelio is a cosmopolitan and speciose group of solitary parasitoids of the eggs of short-horned grasshoppers (Orthoptera: Acrididae). A number of these hosts are important pests, including plague locusts of the genus Schistocerca. Species of Scelio are recognized as potentially important biological control agents, but this possibility has yet to be fully realized, in part because the species-level taxonomy is still incompletely developed. The species of the pulchripennis group have been recently revised. As a continuation of this effort, here we revise the Afrotropical species of Scelio, excluding the pulchripennis species group. Sixty two (62) species are treated, 48 of which are new. Species are classified into the following species groups: ernstii (12 species, 9 new), howardi (23 species, 19 new), ipomeae (6 species, 5 new), irwini (4 species, 3 new), simoni (3 new species) and walkeri (12 species, 9 new). Keys to species groups and to the species within each group are provided. New species described are: S. albatus Yoder, sp. n., S. aphares Yoder, sp. n., S. apospastos Yoder, sp. n., S. ardelio Yoder, sp. n., S. aurantium Yoder, sp. n., S. balo Valerio & Yoder, sp. n., S. bayanga Yoder, sp. n., S. bubulo Yoder, sp. n., S. cano Yoder, sp. n., S. clypeatus Yoder, sp. n., S. concavus Yoder, sp. n., S. copelandi Yoder, sp. n., S. crepo Yoder, sp. n., S. destico Yoder, sp. n., S. dupondi Yoder, sp. n., S. effervesco Yoder, sp. n., S. erugatus Yoder, sp. n., S. exophthalmus Yoder, sp. n., S. fremo Valerio & Yoder, sp. n., S. gemo Yoder, sp. n., S. grunnio Yoder, sp. n., S. harinhalai Yoder, sp. n., S. igland Yoder, sp. n., S. impostor Yoder, sp. n., S. irwini Yoder, sp. n., S. janseni Yoder, sp. n., S. latro Yoder, sp. n., S. memorabilis Yoder, sp. n., S. modulus Yoder, sp. n., S. mutio Yoder, sp. n., S. ntchisii Yoder, sp. n., S. parkeri Yoder, sp. n., S. phaeoprora Yoder, sp. n., S. pilosilatus Yoder, sp. n., S. pipilo Yoder, sp. n., S. quasiclypeatus Yoder, sp. n., S. retifrons Yoder, sp. n., S. ructo Yoder, sp. n., S. scomma Yoder, sp. n., S. simoni Yoder, sp. n., S. simonolus Yoder, sp. n., S. somaliensis Yoder, sp. n., S. susurro Yoder, sp. n., S. tono Yoder, sp. n., S. transtrum Yoder, sp. n., S. tritus Yoder, sp. n., S. ululo Yoder, sp. n., S. vannoorti Valerio & Yoder, sp. n. The following species are redescribed: S. afer Kieffer, S. chapmani Nixon, S. howardi Crawford, S. ipomeae Risbec, stat. n., S. mauritanicus Risbec, S. philippinensis Ashmead, S. remaudierei Ferrière, S. striatus Priesner,S. taylori Nixon, and S. zolotarevskyi Ferrière. The genus Lepidoscelio Kieffer is treated as a junior synonym of Scelio Latreille, syn. n.; its type species, Lepidoscelio fuscipennis Kieffer, 1905 is transferred to Scelio, renamed Scelio obscuripennis Johnson, nom. n. (preoccupied by Scelio fuscipennis Ashmead, 1887), and redescribed. The following additional species are transferred from Lepidoscelio to Scelio: S. cayennensis (Risbec), comb. n., S. insularis Ashmead, rev. comb., S. luteus (Cameron), comb. n., S. thoracicus Ashmead, rev. comb. Lectotypes are designated for S. africanus Risbec, S. ipomeae Risbec, S. mauritanicus Risbec, S. remaudierei Ferrière, S. sudanensis Ferrière, and S. zolotarevskyi Ferrière. Scelio gaudens Nixon is a junior synonym of Scelio striatus Priesner, syn. n.; Scelio africanus Risbec and Scelio clarus Fouts are both junior synonyms of Scelio afer Kieffer, syn. n.; Scelio sudanensis Ferrière and Scelio cheops Nixon are both junior synonyms of Scelio zolotarevskyi Ferrière, syn. n.; Scelio cahirensis Priesner is a junior synonym of Scelio mauritanicus Risbec, syn. n. The name Scelio chapmanni Nixon is an incorrect original spelling, requiring an emendation to S. chapmani.
