Item The Cretaceous scelionid genus Proteroscelio Brues (Hymenoptera, Platygastroidea) ; American Museum novitates, no. 3603(New York, NY : American Museum of Natural History, 2008) Johnson, Norman F.; Musetti, Luciana.; Masner, Lubomir.The genus Proteroscelio Brues is redescribed and P. gravatus, n. sp., is described from Lebanese amber (Aptian age, 112-122 mya). The relationships between Proteroscelio and other scelionids is discussed. The described species of fossil platygastroids are tabulated. The taxa represented by the unavailable names "Eopteromalites fushunensis" Hong, "Leptogasterites brunneus" Hong, "L. furvus" Hong, and "Sinilongicapito guchengziensis" Hong, recently described from Fushun, Liaoning, China (50 mya), should all be classified as scelionids. The replacement name Sinoprotelenomus Zhang n. name is proposed for Protelenomus Zhang, 1989 (preoccupied by Protelenomus Kieffer, 1906).Item The genera of Diapriinae (Hymenoptera, Diapriidae) in the New World. Bulletin of the AMNH ; no. 268(New York, NY : American Museum of Natural History, 2002) Masner, Lubomir.; García R., José Luis.The subfamily Diapriinae (Diapriidae: Proctotrupoidea) in the New World is reviewed at the supra specific level. Three tribes and 52 genera are recognized. Sixteen new genera are proposed: Apopria (Diapriini), Avoca (Diapriini), Chilomicrus (Spilomicrini), Cruzium (Diapriini), Doddius (Spilomicrini), Eladio (Diapriini), Epomium (Spilomicrini), Ferrugenus (Spilomicrini), Hansona (Diapriini), Leucopria (Diapriini), Mimopriella (Diapriini), Omopria (Diapriini), Ortona (Psilini), Peckidium (incertae sedis) Psychopria (Diapriini), and Turripria (Diapriini). The following new species are described: Apopria coveri [female] (USA), Asolenopsia gibba [female] (Costa Rica), Avoca collaris [female] (USA), Chilomicrus pecki [male] (Chile), Cruzium amphorale [female] (Costa Rica), Eladio cruzi [female] (Costa Rica), Epomium cicatrix [female] (Chile), Ferrugenus chilensis [female] (Chile), Hansona pauli [female] (Costa Rica), Leucopria cylindricornis [female] (Ecuador, Costa Rica), Omopria brevipalpis [female] (Brazil), Ortona hansoni [female] (Costa Rica), Peckidium enigmaticum [female] (Antilles, Central and South America, West Africa, Philippines), Psychopria hoguei [male] (Costa Rica), Turripria woldai [female] (Panama). New generic synonymies are proposed: Acanthopria Ashmead (= Adelioneiva Fischer), Asolenopria Kieffer (= Euplacopria Ferrière), Bruchopria Kieffer (= Aulatopria Brèthes), Doliopria Kieffer (= Martinica Risbec), Megaplastopria Ashmead (= Xyalopria Kieffer), Notoxoides Ashmead (= Psilogasteroides Brèthes), Pentapria Kieffer (= Antipapria Fabritius, Bakeria Kieffer, Plutopria Kieffer, Spilomicrinus Ogloblin), Spilomicrus Westwood (= Hoplopria Ashmead, Linkiola Kieffer), Szelenyiopria Fabritius (= Gymnopria Loiácono). New combinations are proposed: Aulatopria tucumana Brèthes to Bruchopria, Bakeria rugosa Dodd to Doddius, Gymnopria lucens Loiácono to Szelenyiopria, Mimopria pentatoma Borgmeier and Mimopria splendens Borgmeier to Mimopriella, and Xanthopria nitida Brues to Acanthopria. The 52 genera are keyed (keys in both English and Spanish); for each genus the synonymies, diagnoses, descriptions, recognition and relationships, distribution, and biology are given. Twelve plates with 107 figures are included.Item The genus Thoron Haliday (Hymenoptera, Scelionidae), egg-parasitoids of waterscorpions (Hemiptera, Nepidae), with key to world species. American Museum novitates ; no. 3452(New York, NY : American Museum of Natural History, 2004) Johnson, Norman F.; Masner, Lubomir.The world fauna of the genus Thoron is revised. The genus is described and Neothoron Masner is treated as a junior synonym (new synonymy). Relationships with Elgonia Risbec and other Scelionidae are discussed and a key to world species is presented. Six new species are described: T. dayi, new species (Indonesia), T. dux, new species (Bolivia, Venezuela), T. garciai, new species (Venezuela, Bolivia), T. rex, new species (Bolivia), Thoron rivalis, new species (Brazil, Panama), and T. spinifer, new species (Ecuador). Thoron metallicus Haliday (Holarctic), T. longicornis Masner and Huggert (USA), and T. lautus (Masner), new combination (Ecuador, Bolivia) are redescribed; the female of T. lautus and the male of T. longicornis are described and keyed for the first time. Thoron gibbus Ruthe is treated as a junior synonym of T. metallicus (new synonymy). Species of Thoron are only known to parasitize the eggs of Nepidae (Hemiptera: Heteroptera) with rearings from Nepa Linnaeus and association with Curicta Stål; apparently the genus Ranatra Fabricius is not a host.Item Janzenella, an enigmatic new genus of scelionid wasp from Costa Rica (Hymenoptera, Platygastroidea, Scelionidae) ; American Museum novitates, no. 3574(New York, NY : American Museum of Natural History, 2007) Masner, Lubomir.; Johnson, Norman F.Janzenella, new genus, is described from the Neotropics (type species: J. innupta, new species). The position of the genus within the superfamily is unclear. Janzenella is characterized by the strongly depressed body, relatively dorsal position of the foramen magnum of the head, and the loosely articulated metasomatic segments with broad laterotergites and no laterosternites.Item Redescription of Archaeoscelio Brues and description of three new genera of Scelionidae (Hymenoptera) : a challenge to the definition of the family ; American Museum novitates, no. 3550(New York, NY : American Museum of Natural History, 2007) Masner, Lubomir.; Johnson, Norman F.; Polaszek, Andrew.Four genera--Archaeoscelio Brues; Cobaloscelio Johnson and Masner, new genus; Plaumannion Masner and Johnson, new genus; and Huddlestonium Polaszek and Johnson, new genus--lack laterotergites and laterosternites in the metasoma, one of the synapomorphies of the superfamily Platygastroidea. The Baltic amber species Archaeoscelio rugosus Brues and Archaeoscelio filicornis Brues are diagnosed and figured, and two species from Baltic amber are described in Cobaloscelio - C. cuspidatus Johnson and Masner, new species and C. speculifer Johnson and Masner, new species. Plaumannion fritzi Masner and Johnson, new species (Brazil) and Plaumannion yepezi Garciá, new species (Venezuela) are described. Huddlestonium exu Polaszek and Johnson, new species is described from São Tomé and the Ivory Coast. The wing venation of Scelionidae is reinterpreted, and the marginal vein of Scelionidae and Chalcidoidea is considered to be a convergent feature.Item Review of genera of the tribe Sparasionini (Hymenoptera, Platygastroidea, Scelionidae), and description of two new genera from the New World ; American Museum novitates, no. 3629(New York, NY : American Museum of Natural History, 2008) Johnson, Norman F.; Masner, Lubomir.; Musetti, Luciana.Five genera in the tribe Sparasionini are described and keyed. Electroteleia Brues (Baltic amber), Sceliomorpha Ashmead (Neotropics) and Sparasion Latreille (Nearctic, Palearctic, Oriental, and Afrotropical regions) are redescribed. Listron Musetti and Johnson, new genus is described from Chile with two species, L. politum Musetti and Johnson, new species (type species of the genus), and L. bilaminatum Masner, new species. Mexon Masner and Johnson, new genus, is described from Mexico, with two new species, M. adelphos Masner and Johnson, new species (type species of the genus), and M. consors Masner and Johnson, new species. The synonymy of Aliofreniger Szabó with Sceliomorpha and of Prosparasion Kieffer with Sparasion are confirmed. Transfer of the type species of Prosparasion, P. coeruleum Kieffer, 1913 into the genus Sparasion makes it a secondary junior homonym of Sparasion coeruleus Kieffer, 1905. The replacement name Sparasion lividus Johnson, Masner, and Musetti is proposed for the junior name to resolve this homonymy. The gender of the name Sparasion is discussed, and we propose that it should be treated as a masculinenoun. The authorship of the family-group name Sparasionini is credited to Dahlbom (1858).Item Revision of world species of the genus Nixonia Masner (Hymenoptera, Platygastroidea, Scelionidae) ; American Museum novitates, no. 3518(New York, NY : American Museum of Natural History, 2006) Johnson, Norman F.; Masner, Lubomir.The world fauna of the genus Nixonia is revised. The genus is described, its relationships with other scelionids are discussed, and a key to world species is presented. Nixonia pretiosa Masner (Namibia) and N. atra Masner (Angola, Democratic Republic of Congo, Kenya, Malawi, Rwanda, Zimbabwe) are redescribed, and 12 new species are described: N. bini, new species (Somalia), N. corrugata, new species (South Africa), N. elongata, new species (South Africa), N. flavocincta, new species (Namibia), N. gigas, new species (South Africa), N. krombeini, new species (India, Laos, Sri Lanka, Thailand, Vietnam), N. lamorali, new species (South Africa), N. pecki, new species (Botswana, South Africa, Zimbabwe), N. priesneri, new species (Egypt), N. sicaria, new species (Namibia), N. stygica, new species (South Africa), and N. watshami, new species (Botswana, Namibia, Zimbabwe). The only host record for the genus is for N. watshami, which been reared from the eggs of Acanthoplus discoidalis (Walker) (Orthoptera: Tettigoniidae, Hetrodinae) in Botswana and Namibia. The phylogenetic relationships among the species are discussed.Item Tyrannoscelio, a new genus of neotropical Scelionidae (Hymenoptera, Platygastroidea) with description of two new species ; American Museum novitates, no. 3551(New York, NY : American Museum of Natural History, 2007) Masner, Lubomir.; Johnson, Norman F.; Arias-Penna, Tania Milena.Tyrannoscelio, new genus is described from the Neotropics (type species: T. genieri, new species). The position of the genus within the Scelioninae is unclear, but the presence of a well-developed skaphion suggests a relationship with Psilanteridini, Thoronini, or Parascelionini. Tyrannoscelio is characterized by a strongly produced frontal ledge and enormously elongate mandibles. Two species are described in the genus: T. genieri, new species from Brazil (Espírito Santo), and T. crenatus, new species from Colombia (Caquetá).
