Descriptions of two new species of the genus Agathis Latreille (Hymenoptera,Braconidae, Agathidinae) from Spain,with a record of mating by one species on flowers

Two new species of the genus Agathis Latreille, A. icarus sp. n. and A. nixoni sp. n., are described from southern Spain. Both species were observed feeding on the nectar of Anacyclus clavatus (Desf.) Pers.. (Asteraceae). A. nixoni was also observed mating on flowers. Mating by parasitoids at feeding sites is discussed.

The Old World genera of braconine wasps (Hymenoptera: Braconidae)

An illustrated key is provided to the Old World genera of Braconinae. In addition, notes are provided on each genus and on a number of characters employed in the key. One new tribe and five new genera based on two existing and three new species are described. The new taxa are as follows: Angustibracon gen. nov. from India (type-species: Bracon leptogaster Cameron, 1899), Bathyaulacini tribus nov. (type-genus: Bathyaulax Szépligeti, 1906), Cassidibracon gen. nov. from West Africa (type-species: Cassidibracon castus sp. nov.), Serraulax gen. nov. from the Afrotropical Region (type-species: Iphiaulax lukombensis Cameron, 1912), Virgulibracon gen. nov. from Australia (type-species: Virgulibracon vulsus sp. nov.) and Vomeribracon gen. nov. from New Guinea (type-species: Vomeribracon amplipenniger sp. nov.). The Pseudodicrogeniini Achterberg, 1976 is synonymized with the Euurobraconini Ashmead, 1900. Ten new generic synonymies are reported: Atanycolimorpha Viereck, 1913 (= Cyanopterus Haliday, 1835), Caenoprymnus Cameron, 1909 (= Soter Saussure, (1890) 1892), Coelodontus Roman, 1912 (= Trigastrotheca Cameron, 1906), Cynodobracon Cameron, 1912 (= Nedinoschiza Cameron, 1911), Iphioilta Ramakrishna Ayyar, 1928 (= Chaoilta Cameron, 1899), Kenema van Achterberg, 1983 (= Trigastrotheca Cameron, 1906), Odontopygia Enderlein, (1918) 1920 (= Trigastrotheca Cameron, 1906), Paraspinaria Cameron, 1905 (= Mesobracon Szépligeti, 1902), Pseudoglyptomorpha Tobias, 1957 (= Pseudovipio Szépligeti, 1896) and Glyptomorpha (Remorpha) Shestakov, 1932 (Pseudovipio Szépligeti, 1896).     

Insects associated with galls of a new species of Eurytomidae (Hymenoptera: Chalcidoidea) on Ephedra nebrodensis in Spain

Galls found on Ephedra nebrodensis in Spain are formed by a species of Eurytoma (Hymenoptera, Chalcidoidea, Eurytomidae) which is described as new. Four other species of Chalcidoidea (two described as new) and one species of Braconidae are parasitoids or inquilines of the eurytomid. An account is given of the biology of the community of insects associated with the gall.     

Cladistics and tribal classification of the Agathidinae (Hymenoptera: Braconidae)

Five tribes of the braconid subfamily Agathidinae are recognized, viz. Agathidini (Blanchard), Cremnoptini (new tribe), Disophrini (new tribe), Earinini (new tribe), and Microdini (Ashmead). Phylogenetic relationships of the tribes are proposed and the phylogenetic placement of the Agathidinae within the Braconidae is discussed. Keys to, and diagnoses of, the tribes are presented.     

Revision of the Palaearctic species of the genus Clinocentrus (Hymenoptera,Braconidae)

Revision of the Palaearctic species of the genus Clinocentrus Haliday is given. The composition and geographic distribution of the genus Clinocentrus and the probable generic position of fossil species described by Brues (1933) as Clinocentrus are discussed. The systematic position of this genus in Exothecinae is also discussed and arguments presented to support the differentiation of exothecines and rogadines. Nine species of Clinocentrus are figured and re-described. Three new species and two new subspecies are figured and described: C. kalmyk from Kalmykia, C. kozlovi from Mongolia, C. rhysipoloides from Primorsk Territory of Russia, C. umbratilis ssp. disruptus from Taiwan and C. vestigator ssp. orientalis from Primorsk Territory of Russia. C. stigmaticus Marshall, 1897 and C. jaroshevskyi Telenga, 1941 are synonymized with C. vestigator (Haliday, 1836); C. tarsalis Ashmead, 1894—with C. exsertor (Nees, 1812) and C. gracilipes (Thomson, 1891)—with C. cunctator (Haliday, 1836), Lectotypes of Exothecus analis Wesmael, 1838 and C. antefurcalis Granger, 1949 are designated. The new combination is given: Rhysipolis antefurcalis (Granger). A key to 12 Palaearctic species of Clinocentrus is given.

A new species of the enigmatic Australian endemic family Trachypetidae (Hymenoptera: Ichneumonoidea): Cercobarcon lasallei sp.n.

ABSTRACT

The Trachypetidae is a newly recognised family of Ichneumonoidea endemic to Australia and one of the most distinctive wasp groups on the continent based on their large body size and superficial resemblance to some ichneumonids and aculeate wasps. The family is united in the presence of a unique sensory or glandular structure at the base of the mandibles. It is known from three genera: Cercobarcon Tobias, 1979, Megalohelcon Turner, 1918 (= Rhamphobarcon Tobias, 1979) and Trachypetus Guérin de Méneville, 1830, totalling eight described species. Trachypetines are rarely encountered, with very few specimens having been collected or recognised in collections since the group was revised in 1993. Here we report on a newly discovered species from Cape York Peninsula, Queensland, the first to be recognised in more than 25 years, and take much pleasure in naming it after Dr John La Salle, in celebration of his career.http://www.zoobank.org/urn:lsid:zoobank.org:pub:3F0147A8-F628-4869-B7FD-2E1560145734     

Cocoon silk chemistry of non-cyclostome Braconidae,with remarks on phylogenetic relationships within the Microgastrinae (Hymenoptera: Braconidae)

Bulk amino acid composition was determined for cocoon silks for 54 species of non-cyclostome braconid wasps collectively representing 14 subfamilies. Little intraspecific variation was encountered either between conspecific individuals of differing origin or between physically different silk layers within a single cocoon. Variation within subfamilies was small except in the Microgastrinae. Most taxa, excluding most microgastrines, had silk of a fairly typical fibroin type with high relative abundances of alanine, serine or glycine (of which either alanine or serine was the most abundant) and usually with moderately low molar concentrations of presumed acidic residues (aspartate/asparagine (As(x)) and glutamate/glutamine (Gl(x))) which ranged from approximately 2% up to nearly 30% (in Helconinae and Blacinae). In the Microgastrinae, members of the genus Microplitis (four species) were similar to the other non-cyclostome subfamilies in having 14.3–26.1 molar % As(x), but the other 10 microgastrine genera investigated produced silks with As(x) the most abundant detected residue comprising 32.4–50.5 molar % while glycine represented less than 10% of residues, indicating an α-helical silk. These data are discussed in the light of some recent independent phylogenetic studies on the Microgastrinae that also suggest a basal position for Microplitis within the subfamily, despite its apparently highly specialized biology.
