The taxonomic placement of several New World and Oriental gasteruptiid wasps (Hymenoptera: Gasteruptiidae)

Abstract

The generic placement of several New World and Oriental gasteruptiid wasps is reviewed. Based on a number of character states, including non-overlapping mandibles (when at rest), the presence of a trochantellus (prefemur) and an exserted ovipositor, and the pattern of the veins in the forewing, five species currently in Pseudofoenus are transferred to Gasteruption L.; namely G. longiceps (Kieffer 1910), n. comb., G. ceylonensis (Enderlein 1912), n. comb., G. maculicorne Cameron 1887, revised comb., G. sericeum Cameron 1887, revised comb., and G. tenuicolle Schletterer 1885, revised comb. In addition, G. longiceps (Kieffer 1910) is a junior secondary homonym of G. longiceps Kieffer 1904 and is renamed G. austini, n. name, and Pseudofoenus neotropicus Schrottky 1906 is placed as incertae sedis.
