A new genus of Entedoninae (Hymenoptera: Eulophidae) from Brazil

Abstract

Neotropical Entomology 32(3): 443-447(2003) Um Novo Gênero de Entedoninae (Hymenoptera: Eulophidae) no Brasil RESUMO -Podkova, um novo gênero, descrito do Brasil, para acomodar sua espécie-tipo, P. hirsuta sp. n. O gênero têm uma aparência peculiar, e suas principais características são um corpo pequeno e compacto densamente piloso na porção dorsal da cabeça e mesosoma, incluindo a parte média do propódeo; cabeça com a carena frontal em forma de ferradura, delimitando a cavidade facial larga com as antenas curtas; e a forma da carena occipital estendendo-se posteriormente para baixo, ao longo das margens posteriores dos olhos. Por essas características Podkova assemelha-se ao gênero Alachua Schauff & Boucek, mas diferindo deste por possuir uma forte carena frontal e o prepecto fortemente sobrepsassado pela margem anterior do mesosterno. Possíveis afinidades com outros gêneros de Entedoninae são discutidas. PALAVRAS-CHAVE: Taxonomia, descrição, região neotropicalABSTRACT -A new genus, Podkova, is described from Brazil to accommodate its type-species P. hirsuta, sp. n. The genus has a peculiar appearance, the main features of which are the small compact body with coarsely pilose dorsal parts of the head and mesosoma, including median part of propodeum, head with sharp frontal carina of horse-shoe shape, delimiting broad facial cavity with rather short antennae, and a sharp occipital carina stretching posteriorly down along hind margins of eyes. By these features, Podkova resembles the genus Alachua Schauff and Boucek, but differs distinctly by having strong frontal carina on the head and the prepectus hardly overlapped by the anterior margin of mesosternum. Possible affinities to some other entedonine genera are discussed.

The neotropical genus Sporrongia Gumovsky (Hymenoptera: Eulophidae), including two new species and the first biological record

“…Description. See Gumovsky (1998). The additional specimen included here is very similar to the holotype of this species and the original description of S. tobagoiensis applies well to this non-type specimen.…”

“…Sporrongia is a very distinctive group morphologically, sharing some features with the tribe Euderomphalini, as mentioned above. It was originally placed in that tribe by Gumovsky (1998) but was later removed from it (Gumovsky 2001) on the grounds that Sporrongia did not have the type of clypeus (delimited as a convex plate with incised anterior margin) and mandibles (with a massive base and semicircularly bent cutting margin) regarded as crucial to define taxa in tribe Euderomphalini. Through the stout and compact body Sporrongia is superficially similar to the Neotropical genus Inti Hansson Hansson 2010, but does not share any of the autapomorphies for that genus.…”

“…The genus Sporrongia Gumovsky was described with a single species, S. tobagoiensis, based on a female specimen caught in a malaise trap on the island of Tobago (Gumovsky 1998). Sporrongia was compared to the Australian genus Horismenoides Girault, as both genera shared features such as a reduced and very short pronotum, a wide mesoscutum with notauli present only anterolaterally and with a median groove, strongly reduced metanotum and a very short propodeum.…”
