Descripción de nueve especies sudamericanas del género Neralsia Cameron, con carena escutelar baja (Hymenoptera: Cynipoidea: Figitidae)

In this study a total of nine new species of the genus Neralsia are described for South America: N. desantisi Jimenez & Pujade-Villar n. sp., N. equilatera Jimenez & Pujade-Villar n. sp., N. hermafrodita Jimenez & Pujade-Villar n. sp., N. marioi Jimenez & Pujade-Villar n. sp., N. moisesi Jimenez & Pujade-Villar n. sp., N. obelix Jimenez & Pujade-Villar n. sp., N. parafossulata Jimenez & Pujade-Villar n. sp., N. pseudoneralsia Jimenez & Pujade-Villar n. sp. and N. rauli Jimenez & Pujade-Villar n. sp., all of them have in common the low carina separating the scutellar foveae. Other six known Neralsia species, N. albipennis (Kieffer), N. bogotensis (Kieffer), N. flavidipennis (Kieffer), N. fossulata (Kieffer), N. pilosa (Borgmeier) and N. striaticeps (Kieffer) have the same scutellar character. The morphological characters to differentiate all mentioned species are presented.

Revision of the Species of Neralsia (Hymenoptera: Figitidae: Figitinae) from North America

Abstract In North America, only two species of Neralsia Cameron can currently be considered valid: N. hyalinipennis Ashmead and N. incompleta Jiménez & Pujade-Villar. Claims that Neralsia nigriventris (Kieffer) and N. armata (Say) also should be considered as such are dubious. Here, four new species found in the United States and Canada are described: Neralsia ashmeadi Jiménez & Pujade-Villar sp. nov., Neralsia kiefferi Jiménez & Pujade-Villar sp. nov., Neralsia weldi Jiménez & Pujade-Villar sp. nov., and Neralsia readae Jiménez & Pujade-Villar sp. nov. Their main morphological characters are described and a key is provided so as to distinguish between these North American species.

Description of a new species of Neralsia Cameron with a wide distribution in the American continent: N. incompleta n. sp. (Hymenoptera: Figitidae: Figitinae)

Abstract In this study a new species of Neralsia is described, N. incompleta n. sp. The radial cell shape allows to distinguish it clearly from the rest of species of the genus. The distribution of Neralsia incompleta n. sp. is probably the entire American continent, having been collected from Canada to Paraguay. In spite of its abundance, the associated biology is unknown, although it should be related with parasitism of Diptera Cyclorrhapha.
