About: Megalyridae

An Entity of Type: insect, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Megalyroidea is a small hymenopteran superfamily of wasps that includes a single family, Megalyridae, with eight extant genera (plus around a dozen extinct ones) and 49 described species. Modern megalyrids are found primarily in the southern hemisphere, though fossils have only been found in the northern hemisphere. The most abundant and species-rich megalyrid fauna is in Australia. Another peak of diversity appears to be in the relict forests of Madagascar, but most of these species are still undescribed.

dbo:abstract
  • Die Megalyridae sind eine Familie der Hautflügler (Hymenoptera), sie gehören dort zu den ursprünglicheren Taillenwespen mit parasitoider Lebensweise ("Legimmen", Terebrantia oder auch Parasitica). Die Familie umfasst etwa 50 rezente Arten, die weltweit in den Tropen und den gemäßigten Breiten der Südhalbkugel leben, eine Art nördlich bis Japan. Die Namensgebung leitet sich von dem extrem langen Legebohrer der Arten der australischen Gattung ab ("Langschwanz" von altgriech megal-yra, eigentlich: -ura), deshalb werden die Megalyridae im Englischen manchmal als "long tailed wasps" bezeichnet.

  • Megalyroidea is a small hymenopteran superfamily of wasps that includes a single family, Megalyridae, with eight extant genera (plus around a dozen extinct ones) and 49 described species. Modern megalyrids are found primarily in the southern hemisphere, though fossils have only been found in the northern hemisphere. The most abundant and species-rich megalyrid fauna is in Australia. Another peak of diversity appears to be in the relict forests of Madagascar, but most of these species are still undescribed. Historically, there has been much confusion about the definition of this family. Species now placed in Megalyridae have in the past been classified into as many as six other families (Braconidae, Evaniidae, Ichneumonidae, and Stephanidae, as well as Dinapsidae and Maimetshidae, with Dinapsidae now considered to be within the Megalyridae. Maimetshidae is no longer considered closely related to Megalyridae, and has been included in Trigonaloidea with Trigonalidae. The oldest fossils confidently identifiable as Megalyrids date to the Early Cretaceous. The best defining feature, unique to the family, is the mesothoracic spiracle has moved, and is actually located in the upper corner of the pronotum, though this is a fairly obscure feature to see. Perhaps the most useful visible character is that the base of the antenna fits into a wide, concave groove below the eye, though a few other wasp families exhibit this trait. Females of have ovipositors ranging from five to eight times their body length, but this is not true of the other genera. The largest known megalyrid is the female of the Australian , with a body length of 22 mm (0.9 in) and ovipositor length of 82 mm (3.2 in). The smallest known megalyrid is the Brazilian , with a body length of 2.9 mm (0.1 in) and ovipositor 1 mm (0.0 in) long. Megalyrid wasps are thought to be idiobiont endoparasitoids of concealed insect larvae. One Australian species, , attacks the larvae of , a mud-nesting crabronid wasp. Oviposition habits of Megalyridae are regarded as quite primitive, with field observations suggesting they simply poke their ovipositors into pre-existing cavities, holes, or cracks, rather than drilling into the substrate as in other Apocrita.

  • Les mégalyridés (famille Megalyridae), sont des hyménoptères parasites de la super-famille Megalyroidea. Elles tirent leur nom de leur ovipositeur sur-développé prenant en vol la forme d'une lyre. Elles sont parfois référées en tant que "Guêpes à longue queue" bien que les proportions de l’ovipositeur ne soit pas exceptionnels parmi les hyménoptères. (fr)

  • Megalyroidea é uma pequena superfamília de himenópteros que inclui uma única família, Megalyridae, com oito géneros (mais três já extintos) e pelo menos 45 espécies extantes. Os membros actuais podem ser encontrados principalmente em florestas tropicais primárias , com poucos representantes no Novo Mundo. A fauna mais abundante e rica em espécies localiza-se na Austrália. Outro pico de diversidade parece ser nas florestas relictas de Madagáscar, mas a maioria dessas espécies permanece por descrever. Historicamente, tem havido confusão acerca da definição desta família. Espécies agora colocadas nesta família eram no passado classificadas em até 6 outras famílias, Braconidae, Evaniidae, Ichneumonidae e , assim com nas famílias Dinapsidae e Maimetshidae, as duas últimas consideradas actualmente como parte das Megalyridae. A característica mais distintiva desta família é o reposicionamento do espiráculo que actualmente está localizado no canto superior do pronoto, embora seja uma característica obscura de se ver. Talvez a característica mais visível é a base da antena que encaixa num amplo sulco abaixo do olho, embora outras famílias de vespas também terem esta característica. As fêmeas do género possuem ovopositores que podem atingir até 5 a 8 vezes o tamanho do corpo. O maior membro conhecido desta família, é a fêmea da espécie australiana, , com um comprimento corporal de 22 mm e o ovipositor com 82 mm. O mais pequeno trata-se da espécie brasileira , com um comprimento corporal de 2,9 mm e um ovopositor de 1 mm. (pt)
