The Cretaceous Scelionid Genus Proteroscelio Brues (Hymenoptera: Platygastroidea)

Abstract 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).

Review of Genera of the Tribe Sparasionini (Hymenoptera: Platygastroidea, Scelionidae), and Description of Two New Genera from the New World

Abstract 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 masculine noun. The authorship of the family-group name Sparasionini is credited to Dahlbom (1858).

A new fossil species of the Australian endemic genus Peradenia Naumann & Masner (Hymenoptera: Proctotrupoidea, Peradeniidae) from Baltic Amber

The family Peradeniidae (Hymenoptera: Proctotrupoidea) is represented by two rare extant species from southeastern Australia (Australian Capital Territory, Victoria, Tasmania). A new species, Peradenia galerita sp. n., is described from Eocene Baltic amber. The fossil species is very similar to the living Perndenia, but has the short metasomatic petiole typical of most Proctotrupoidea. The subfamily classification of Heloridae proposed by Rasnitsyn and the status of Peradeniidae are briefly reviewed. The subfamily Mesohelorinae Rasnitsyn, 1990 is a junior synonym of Protohelorinae Rasnitsyn, 1980 (syn. n.).

REDEFINITION OF THE GENUS PHANUROMYIA DODD (HYMENOPTERA: SCELIONIDAE)

Abstract The concept of the Australian genus Phanuromyia Dodd is expanded to include 9 species: P. bidentata n. sp., P. flavescens (Dodd) new combination, P. hysteropteri (Bin) new combination, P. necopinata Dodd, P. obscuripes (Pélov) new combination, P. oocida (Pélov) new combination, P. pulcherrima (Dodd) new combination, P. rufobasalis Dodd, and P. sacchii (Ogloblin) new combination. Representatives have been found worldwide, but the greatest diversity is in the Old World. The known hosts are eggs of Issidae and Fulgoridae (Hemiptera: Fulgoromorpha). The genus is contrasted with the crassiclava species group of Telenomus, another group also known to attack species of fulgoromorphs.

Redescription and revision of the Neotropical genus Pseudoheptascelio Szabó (Hymenoptera, Platygastridae, Scelioninae), parasitoids of eggs of short-horned grasshoppers (Orthoptera, Acrididae)

Abstract The genus Pseudoheptascelio Szabó is redescribed and its species revised. We recognize four species: Pseudoheptascelio muesebecki Szabó, Pseudoheptascelio cornopis Masner, Pseudoheptascelio tico sp. n. and Pseudoheptascelio rex sp. n. The genus is found from Guatemala south to the Brazilian state of Rio Grande do Sul. The species Pseudoheptascelio cornopis is recorded as a parasitoid of the eggs of Cornops aquaticum (Bruner) on water hyacinth, Eichhornia crassipes (Mart.) Solms.
