A new genus of Encyrtidae (Hymenoptera: Chalcidoidea) from India

A new genus, probably related to Anagyrus, is erected for a new species parasitic on mealy-bugs, the male and female of which are described.     

Attraction of Encyrtid wasps (Hymenoptera,Chalcidoidea: Encyrtidae) to a peach orchard agrocenosis in the Republic of Moldova

A total of 26 species from 19 genera of Encyrtidae were recorded in peach orchards in the environs of Chisinau, Moldova. The species affecting the numbers of such peach pests as the Oriental fruit moth Grapholita molesta Busck, the peach twig borer Anarsia lineatella Z., the San Jose scale Diaspidiotus perniciosus Comst., and the gooseberry scale Eulecanium coryli L., are listed. The encyrtid parasites of the potential peach pests in Moldova, and also the hyperparasites and parasites of beneficial predatory insects, are considered. Proteincarbohydrate mixture (PCM) and methyl salicylate (MeSA) were most effective for attraction of encyrtid wasps in April and the first half of May, providing 7.0- and 3.2-fold increase in the parasite numbers as compared with the control. In the second decade of May and in June, the increase was 3.6 times on PCM, 1.8 times on MeSA, and 2.6 times on nectariferous plants. From the end of June the efficiency of PCM and MeSA only slightly exceeded the control level while nectariferous plants were most effective, yielding a more than twofold increase in the numbers of encyrtids.     

A new species of the chalcid-wasp genus Ericydnus walker (Hymenoptera, Chalcidoidea, Encyrtidae) from West Siberia

A new species, Ericydnus novosibiricus sp. n., is described. The main characters differentiating the new species from the similar E. longicornis Dalman are as follows: female??fore wing noticeably shortened, with almost normally developed veins and rounded apex, marginal vein longer than postmarginal vein, 6th flagellar segment slightly longer than wide, club truncate; male??fore wing noticeably shortened, with almost normally developed veins and pointed apex, flagellar segments subsequently becoming wider toward antennal apex.     

A review of encyrtid wasps of the genus <Emphasis Type="Italic">Anicetus</Emphasis> Howard, 1896 (Hymenoptera,Chalcidoidea, Encyrtidae) of the new world,Hawaiian Islands,and Australia with description of new species from Mexico

The review contains a characteristic (with diagnosis) of the genus Anicetus Howard, 1896, a key to the females of the 12 species known from the New World, the Hawaiian Islands, and Australia, and a synopsis of the species with data on their distribution, hosts, biology, ecesis, and use in biological control of injurious coccids. Two new species are described from Mexico: Anicetus myartsevae sp. n. and A. villarreali sp. n. Anicetus carolinensis J. Meyer, 2001 from the USA is excluded from the genus and transferred to Homosemion Annecke, 1967. A new combination is established: Anicetus argentinus (Fidalgo, 1979), comb. n. from Paraceraptrocerus Girault, 1920, which is a synonym of Anicetus. The paper is based on the author’s work in the insect depositories of the USA (Washington, San Francisco, and Riverside), Mexico (Ciudad Victoria), and Russia (St. Petersburg). Anicetus myartsevae sp. n. is compared with the Mexican A. primus (Howard, 1898), from which it differs in the antennal scape half as long dorsally as at base (as long as that in A. primus), the legs more or less extensively dark (mainly yellow in A. primus), and the face with a dark transverse stripe (without stripe in A. primus). Anicetus villarrieli sp. n. is a short-winged species.

Five new species and one subspecies with one or without any transverse hyaline bands on the forewings are described from Israel.     

New species of chalcidoid wasps of the family Eurytomidae (Hymenoptera,Chalcidoidea) from arid Palaearctic regions

Five new species of chalcidoid wasps of the family Eurytomidae are described: four from Israel and one from Kazakhstan. Tetramesa pavliceki Zerova, sp. n. (cylindrica species group) is closely related to T. scheppugi Schlecht., but differs in the more elongate flagellar segments, longer genae, and smooth metasomal tergites. Eurytoma nevoi Zerova, sp. n. is similar to E. sabulosa Erd. and E. bicolorata Zer. (phragmiticola species group), differs from these species in the longer marginal vein, punctate propodeum, and longer flagellar segments. E. oreni Zerova, sp. n. belongs to the fumipennis species group. It is closely related to E. monticola Zer., but differs in the more convex scape, longer postmarginal vein, and yellow legs. E. simutniki Zerova, sp. n. belongs to the robusta species-group. It resembles E. heriadi Zer., but differs in the longer flagellar segments of the female and in the shorter postmarginal vein. Nikanoria mamayevi Zerova, sp. n. is similar to N. stigma Zer., but differs in the more elongate metasoma, longer flagellar segments of both sexes, and larger yellow spots on the pronotum.     

New data on the Pteromalid wasps (Hymenoptera,Chalcidoidea: Pteromalidae) of the Russian Far East

Fourteen genera (Ardilea Graham, Glyphognathus Graham, Rhicnocoelia Graham, Eulonchetron Graham, Habritys Thomson, Heteroprymna Graham, Janssoniella Kerrich, Lyubana Bou?ek, Muscidifurax Girault et Sanders, Nazgulia Hedqvist, Notoglyptus Masi, Oxysychus Delucchi, Platygerrhus Thomson, and Stenetra Masi) and 81 species are recorded for the first time for the fauna of Russia; in addition, 13 species are new to the fauna of the Russian Far East.     

A molecular phylogeny of the Chalcidoidea (Hymenoptera)

Chalcidoidea (Hymenoptera) are extremely diverse with more than 23,000 species described and over 500,000 species estimated to exist. This is the first comprehensive phylogenetic analysis of the superfamily based on a molecular analysis of 18S and 28S ribosomal gene regions for 19 families, 72 subfamilies, 343 genera and 649 species. The 56 outgroups are comprised of Ceraphronoidea and most proctotrupomorph families, including Mymarommatidae. Data alignment and the impact of ambiguous regions are explored using a secondary structure analysis and automated (MAFFT) alignments of the core and pairing regions and regions of ambiguous alignment. Both likelihood and parsimony approaches are used to analyze the data. Overall there is no impact of alignment method, and few but substantial differences between likelihood and parsimony approaches. Monophyly of Chalcidoidea and a sister group relationship between Mymaridae and the remaining Chalcidoidea is strongly supported in all analyses. Either Mymarommatoidea or Diaprioidea are the sister group of Chalcidoidea depending on the analysis. Likelihood analyses place Rotoitidae as the sister group of the remaining Chalcidoidea after Mymaridae, whereas parsimony nests them within Chalcidoidea. Some traditional family groups are supported as monophyletic (Agaonidae, Eucharitidae, Encyrtidae, Eulophidae, Leucospidae, Mymaridae, Ormyridae, Signiphoridae, Tanaostigmatidae and Trichogrammatidae). Several other families are paraphyletic (Perilampidae) or polyphyletic (Aphelinidae, Chalcididae, Eupelmidae, Eurytomidae, Pteromalidae, Tetracampidae and Torymidae). Evolutionary scenarios discussed for Chalcidoidea include the evolution of phytophagy, egg parasitism, sternorrhynchan parasitism, hypermetamorphic development and heteronomy.     

New species of parasitoid wasps of the family Eurytomidae (Hymenoptera, Chalcidoidea) from the United Arab Emirates

Two new species of the genus Eurytoma, Eu. emirata Zerova, sp. n. and Eu. cornutella Zerova, sp. n., and two new species of the genus Nikanoria, N. globosa Zerova, sp. n. and N. cuspidata Zerova, sp. n., are described from the United Arab Emirates. This is the first record of genera and species of Eurytomidae from the United Arab Emirates. Holotypes and paratypes of the new species are deposited in the collection of Institute of Zoology, the National Academy of Sciences of Ukraine (Kiev).     

A revision of the dinocarsiine Encyrtidae with a study of the genus Pelmatencyrtus De Santis (Hymenoptera: Chalcidoidea)

This paper constitutes a revisionary treatment of the Encyrtid subtribe Dinocarsiina as defined by Kerrich (1967). The genera there listed are studied, together with Praleurocerus Agarwal and Aeptencyrtus De Santis, which are here included. Encyrtolophus De Santis is treated as a subgenus of Chrysoplatycerus Ashmead although it is very distinct from the type species of that genus. A new genus is proposed for Tropidophryne flandersi Compare. All specíes are redescribed with exception of two belonging to monotypic genera. Five species are described as new.

Entedoninae wasps (Hymenoptera, Chalcidoidea, Eulophidae) associated with ants (Hymenoptera, Formicidae) in tropical America, with new species and notes on their biology

Three new species of Eulophidae associated, or presumed to be associated with ants are described: two species of Horismenus Walker and one species of Microdonophagus Schauff. Information on the biology is also included. The two Horismenus species are from Chiapas, Mexico. Horismenus myrmecophagussp. n. is known only from females and is a gregarious endoparasitoid in larvae of the weaver ant Camponotus sp. ca. textor. The parasitoids pupate inside the host larva, and an average of 6.7 individuals develops per host. This is the second time a species of genus Horismenus is found parasitizing the brood of a formicine ant of genus Camponotus. Horismenus microdonophagussp. n. is described from both males and females, and is a gregarious endoparasitoid attacking the larvae of Microdon sp. (Diptera: Syrphidae), a predator on ant brood found in nests of Camponotus sp. ca. textor. The new species of Microdonophagus, Microdonophagus tertius, is from Costa Rica, and known only from the female. Nothing is known about its biology but since another species in same genus, Microdonophagus woodleyi Schauff, is associated with ants through its host, Microdon larva (with same biology as Horismenus microdonophagus), it is possible that also Microdonophagus tertius has this association. A new distributional record for Microdonophagus woodleyi is also reported, extending its distribution from Panama and Colombia to Brazil.

Propsyllaephagus Blanchard is synonymized with Psyllaephagus Ashmead (syn.n), Aratiscus laevigatus De Santis is transferred to Zeteticontus Silvestri (comb n.) and a key to the South American species of the genus is provided.     

Taxonomy of the genusTrichogramma (Hymenoptera,Chalcidoidea, Trichogrammatidae)

Résumé Dans le genreTrichogramma, il existe d'une part un certain nombre d'espèces et, d'autre part, beaucoup de formes biologiques caractérisées seulement par leur comportement. Les espèces bien distinctes par leur morphologie sont:T. evanescens Westwood,T. embryophagum (Hartig),T. semblidis (Aur.,T. minutum Riley,T. japonicum Ash. etT. retorridum (Gir.). La valeur d'une espèce deTrichogramma est établie par le mode de reproduction, la variation de la coloration, la durée du cycle évolutif et les différences des soies des antennes chez les males, et tout cela pour une température haute et constante (30°C). La connaissance des modifications physiologiques et des changements de coloration d'une espèce en fonction de l'habitat est importante pour les études taxonomiques qu'il faut exécuter avec un matériel vivant. La tache d'un taxonomiste deTrichogramma est biologiquement difficile, mais son importance pour l'agriculture est considérable.      

Review of the Late Eocene Encyrtidae (Hymenoptera,Chalcidoidea) with a description of the first fossil genus with filum spinosum

Glaesus gibsoni gen. et sp. nov. and Eocencnemus gedanicus sp. nov. are described from materials stored in the amber collection of the University of Gdańsk. Eocencyrtus zerovae Simutnik, 2001 is for the first time recorded in the Baltic amber. The encyrtids recorded in Eocene ambers are reviewed, and a key to the known genera is given. The fossil Encyrtidae cannot be placed with confidence in any of the established subfamilies. Their comparative morphology is analyzed. One of the diagnostic characters of the subfamily Encyrtinae, the presence of the filum spinosum, is recorded for the first time for fossil encyrtids (in G. gibsoni).
