BACKGROUND: The checklist of British and Irish Ichneumonidae is revised, based in large part on the collections of the Natural History Museum, London and the National Museums of Scotland, Edinburgh. Distribution records are provided at the country level. NEW INFORMATION: Of the 2,447 species regarded as valid and certainly identified, 214 are here recorded for the first time from the British Isles. Neorhacodinae is considered to be a separate subfamily rather than a synonym of Tersilochinae...

The Australian insect fauna is among the least-well studied in the world, and conservative estimates state that 75% of the species still await description. In the more species-rich groups, this percentage might be even larger, which is certainly the case in parasitoid wasps which have received very little attention by taxonomists. The genus Pristomerus of the family Ichneumonidae is distributed worldwide, with most species found in the tropics. Its members attack concealed larvae of small Lepidoptera, and several species are used in biocontrol...

The taxonomic knowledge about Brazilian Ichneumonidae species is still incipient, especially for groups poorly represented in the Neotropics, like Ctenopelmatinae. The genus Lathrolestes Förster, 1869, mainly Holarctic, is here recorded for the first time to Brazil, with description of L. piranga Lima & Kumagai sp. n. and L. pitunauassu Lima & Kumagai sp. n. Additionally, a key to the Neotropical species is provided.

We describe three new species of parasitoid wasps of the genus Atractodes (Ichneumonidae: Cryptinae) from South America: A. colchaguensis sp. nov. from Chile, and A. pleuripunctatus sp. nov. and A. saragurensis sp. nov. from Ecuador. These species are all characterized by a densely and strongly punctate mesopleuron. The Atractodes pleuripunctatus species-group is defined to accommodate the new species. In addition, the second part of the key to species of the Neotropical Atractodes including this species-group is given...

A new ichneumonid-species Rhorus koreensis sp. nov. is described from South Korea. Monoblastus jinjuensis Lee et Cha, 1993 described from South Korea is transferred to Rhorus (new combination). Only Rh. takagii (Uchida, 1931) is recorded previously from South Korea. Rhorus nigritarsis (Hedwig, 1956) is recorded for the first time from South Korea. A key to the four South Korean species are provided.

The genus Asthenara Förster, 1869, belonging to the tribe Pionini of the subfamily Ctenopelmatinae (Hymenoptera, Ichneumonidae), comprises eight described species (Yu et al. 2012). Two of them are distributed in the Palaearctic Region, and six in the Neotropical region. One Neotropical species is known from Costa Rica (Gauld et al. 1997), the remaining five from Mexico (Kasparyan 2006). Kasparyan (2006) provided a key to the species from the Mexico. To date, no species of the genus have been described from Nearctic region or south of Costa Rica...

The diamondback moth (DBM) (Plutella xylostella) is one of the main pests of brassicaceous crops worldwide and shows resistance against a wide range of synthetic insecticides incurring millions of dollars in control costs every year. The DBM is a prime example of the introduction of an exotic species as a consequence of globalization. In this study we analyzed the genetic population structure of the DBM and two of its parasitic wasps, Diadegma semiclausum and Diadegma fenestrale, based on mitochondrial DNA sequences...

Apical serrations of the hymenopteran ovipositor have been widely postulated to originally constitute adaptations for cutting through hard substrates. Simplifications of the ovipositor tip have occurred in several ichneumonid wasp genera associated with spiders. Despite such reduction in Clistopyga (Hymenoptera, Ichneumonidae), the ovipositor still possesses some apical serrations. Through the first detailed study, we believe, on the behaviour of an ovipositing Clistopyga species, we show that it can alter its ovipositor for different purposes and that the primary function of the apical serrations is clinging to its spider host as the spider attempts to escape...

We revise the Taiwanese species of the ophionine genus Leptophion Cameron, 1901. As a result, three species, including a new species, are recognized. Two of them were identified as L. maculipennis (Cameron, 1905) and L. radiatus (Uchida, 1956), both of which had been previously recorded in Taiwan; we redescribe them based on Taiwanese specimens. We describe a single new species as L. giganteus Shimizu & Watanabe, sp. nov. The phenology and distribution of the species are briefly discussed. A key to the Taiwanese species of Leptophion and additional couplets to the key proposed by Gauld & Mitchell (1981) are also provided...

Larvae of necrophagous flies in the families Calliphoridae, Sarcophagidae and Muscidae are the main exploiters of decaying organic matter. Knowledge of insect species associated with each stage of decay can be used to estimate the time since death in the crime scene. Dipteran larvae are attacked by a rich community of parasitoids, including species of Braconidae, Ichneumonidae and Pteromalidae (Hymenoptera: Parasitica). This study examined the parasitic complex associated with flies of forensic and sanitary importance in the city of Córdoba (Argentina)...

The seasonal pattern of parasitism by a parasitoid can be influenced by many factors, such as interspecific competition and host instar preference. We conducted field and laboratory experiments to describe the seasonal pattern of parasitism of spruce budworm Choristoneura fumiferana (Clemens) larvae by Tranosema rostrale (Brischke), and to investigate whether this pattern can be explained by interaction with other parasitoid species, or by host instar preference. Larval survival, developmental time, sex ratio, and adult size of T...

The Neotropical species of the cryptine genus Atractodes are studied, and four species-groups are proposed. In this paper, A. altoandinus and A. propodeator species-groups are diagnosed. The former species-group occurs from southern Mexico to Brazil and includes some of the largest Atractodes species ever found, all possessing a strongly sloped propodeum; the latter species-group is only known from the Chilean Andes and includes one of the smallest species of Atractodes, characterised by a very short and curved tergite I and short first flagellomere...

Two Japanese species of the genus Ishigakia Uchida, 1928, i.e., the type species from Ryukyus, I. exetasea Uchida, and a new species from Honshu, I. albitarsa Ito & Maeto sp. nov., are (re-)described. Antennal tapping and oviposition behavior of female I. exetasea was observed on the stalks of Japanese silvergrass Miscanthus sinensis. The new species, I. albitarsa, has (presumably) close relatives from mainland China and, disjunctely, from South Africa. A key to the world species of Ishigakia is also provided...

The genus Pion Schiødte, 1839, is newly recorded from Japan based on a new species, P. japonicum sp. nov. This species closely resembles the Chinese species P. qinyuanensis Chen, Sheng & Mao, 1998, but it can be distinguished from the following combination of character states (male of P. qinyuanensis is unknown): lateromedian longitudinal carina of propodeum completely parallel, not convergent anteriorly (almost parallel but slightly convergent anteriorly in P. qinyuanensis); malar space 0.6 times as long as basal width of mandible (0...

Parasitoid wasps are excellent organisms for studying the allocation of host resources to different fitness functions such as adult body mass and development time. Koinobiont parasitoids attack hosts that continue feeding and growing during parasitism, whereas idiobiont parasitoids attack non-growing host stages or paralyzed hosts. Many adult female koinobionts attack a broad range of host stages and are therefore faced with a different set of dynamic challenges compared with idiobionts, where host resources are largely static...

BACKGROUND: The genus Phytodietus Gravenhorst, 1829 is a species rich group of ichneumonid parasitoid wasps. It is represented in all zoogeographical regions, but knowledge of Phytodietus species in the Oriental region is patchy and restricted to some countries. NEW INFORMATION: Here the genus Phytodietus is recorded from Thailand for the first time based on three species. Diagnosis and illustrations of P. longicauda (Uchida, 1931), P. pitambari Kaur et Jonathan, 1979 and P...
