The relationships of the genusAustralomymar [Hymenoptera: Mymaridae]

The holotype female ofAustralomymar aurigerum Girault is redescribed and figured. Comparative data on the types of the five described species ofPolynemoidea Girault are given, and the affinities of both genera briefly discussed.

Species of the generaPromuscidea Girault andProspaltella Ashmead [Hymenoptera: Aphelinidae] from India

The systematic position of the genusPromuscidea Girault is discussed. Two species ofPromuscidea (P. unfaciativentris Girault andP. longiclavata sp. n.) and one species ofProspaltella Ashmead (P. terebrator sp. n.) from India are described in detail.     

The species of "Ichneumon" (Hymenoptera) described by Linnaeus

Ichneumonidae in the Linnaean and other collections have been critically assessed with regard to their status as type-specimens of species described by Linnaeus. The generic placements of the 56 nominal species of Ichneumonidae (54 originally in Ichneumon and two in Mutilla) described by Linnaeus are established after study of the extant type-material. Lectotypes are designated for eleven of the species and one new synonymy is established. Notes are given on the 33 species originally described by Linnaeus in Ichneumon but now placed in other families.

The species of Hymenoptera described by Linnaeus in the genera Sphex, Chrysis, Vespa, Apis and Mutilla

Data are presented on the type-material representing the species described by Linnaeus in his genera Sphex, Chrysis, Vespa, Apis and Mutilla , The names here considered total 158; six are currently applied in the Hymenoptera Parasitica. Of the balance of 147, three are emendations and five are unavailable homonyms or names proposed in the synonymy of other species. Fifteen Linnaean names are here placed as synonyms. One name is attributed to an author other than Linnaeus, and live names remain species incertae sedis. The remainder, 118, are applied as valid names in die Hymenoptera Aculeata. Holotype specimens in London, Uppsala or Stockholm represent 60 names; 55 names are based on lectotype specimens of which 49 are here designated, two by other authors. One name is represented by a neotype specimen in Lund, and one by a lectotype figure. One non-aculeate species is based on syntypes. Specimens appear to be lost with respect to 25 names; three specimens in Uppsala may be the holotypes of a further three species.
Eight new combinations are made, and twelve new synonyms established; three further new combinations and three further new synonymies are suggested. A systematically arranged summary of species treated and of nomenclatural changes made is given. Nomenclatural changes affecting non-Linnaean names are included where relevant; lectotypes are designated for two non-Linnaean species.     

Achrysocharoides Girault (Hymenoptera, Eulophidae) new to tropical America, with eight new species

The genus Achrysocharoides Girault is here reported for the first time from tropical America. Included are ten species, eight newly described: Achrysocharoides asperulus, Achrysocharoides callisetosus, Achrysocharoides cuspidatus, Achrysocharoides foveatus, Achrysocharoides infuscus, Achrysocharoides mediocarinatus, Achrysocharoides purpureus, Achrysocharoides sulcatus, and two already known: Achrysocharoides ecuadorensis (Hansson) and Achrysocharoides gliricidiae (Hansson & Cave). All species are included in an identification key, diagnosed, described and illustrated. Only one of the species, Achrysocharoides gliricidiae, has a host record, an endoparasitoid in a leafmining Gracillariidae (Lepidoptera) on Gliricidia sepium (Fabaceae), thus conforming to the biology of extralimital Achrysocharoides species. The genus Kratoysma Bouček is here established as a junior synonym of Achrysocharoides, and the following species previously in Kratoysma are here recombined to Achrysocharoides: Kratoysma citri Bouček, Kratoysma ecuadorensis Hansson, Kratoysma gliricidiae Hansson & Cave, Kratoysma longifacies Hansson, Kratoysma nepalensis Hansson, Derostenus usticrus Erdös.

Three new species ofTrichogramma [Hymenoptera: Trichogrammatidae] from India

Three new species ofTrichogramma occurring in India are described. Two of these were reared from eggs of the sugarcane stem-borerChilotraea infuscatellus, while the third was found attacking eggs ofAchaea janata, Tiracola plagiata andHeliothis armigera. The diagnostic value of the male genitalia in this genus is emphasized and a discussion is presented justifying the consideration of these as new species.

The male and female first instar larvae of Anaphes victus and A. listronoti (Hymenoptera, Mymaridae)

 Anaphes victus and A. listronoti are two closely related species, respectively solitary and gregarious parasitoids of eggs of the carrot weevil Listronotus oregonensis (Coleoptera, Curculionidae). Both species are sympatric, and the regulation of super- and multiparasitism that occurs regularly in this host is done by larval fights between the mymariform first instar larvae. The morphology of both male and female first instar larvae of A. victus and A. listronoti is described using scanning electron microscopy. Both species have first instar larvae of the mymariform type and present sexual dimorphism. The main difference between the two species is that larvae of A. victus are clearly segmented while larvae of A. listronoti show no visible segmentation. Male larvae of both species have two types of perioral hooks, longer and less dense dorsal setae than females and developed undertail spines. Female larvae of both species have short abdominal setae. These morphological differences are discussed in the context of intra- and interspecific larval competition. Accepted: 25 May 1997     

Laboratory rearing ofAnaphes sordidatus [Hym.: Mymaridae] on carrot weevil eggs [Col.: Curculionidae]

A technique for rearingAnaphes sordidatus (Girault) on eggs of laboratory-reared carrot weevil,Listronotus oregonensis (Le Conte), is described. Individual rearing was possible by using polyethylene embedding capsules that enabled easy manipulation of parasitized carrot weevil eggs for use in subsequent experimental procedures. The technique described resulted in 65% parasitization of carrot weevil eggs and 90 mn per day were sufficient to obtainca. 200 parasites daily.
