The neotropical genus klyngon hansson (Hymenoptera: Eulophidae), with new species and biological information

Abstract

The genus Klyngon Hansson is revised and expanded to include 13 species, 11 of which are newly described: K. albicornis, K. aulacis, K. brasilense, K. copaiferae, K. costalimai, K. gibberum, K. guimaraesi, K. hortense, K. pegosoma, K. petalon, K. serjaniae. The inclusion of the new species necessitates a change of the morphological definition of the genus and diagnostic characters are modified or abandoned and new characters are introduced. The new species are described and diagnosed and all species are included in a key. The variation in the number of setae on midlobe of mesoscutum, scutellum and submarginal vein is discussed in terms of diagnostic characters for the subfamily, and the consequences of this variation for the identification of the genus with existing keys are highlighted, with a suggested solution to this problem. Biological records are available for 7 of the species, and all records are from unidentified galls, 4 species from Copaifera langsdorffii (Fabaceae), 2 species from Serjania mexicana (Sapindaceae), and 1 species from an unidentified liana. Klyngon is regarded as a basal group within the tribe Entedonini and the association with galls is here speculated to be a primitive biology for the tribe. Copyright © 2010 .Magnolia Press.
