<p><strong>The Neotropical species of <em>Xanthopimpla</em> Saussure (Hymenoptera: Ichneumonidae: Pimplinae)</strong></p>

Abstract

Xanthopimpla Saussure, 1892 is one of the largest and best studied genera of the family Ichneumonidae. It is most species rich in the Oriental and Afrotropical regions with only a few species occurring in Central and South America. The present study reviews the Neotropical species of the genus including descriptions of four new species from Amazonia and Northeast South America. We define a new species group: the amazonica species-group, to accommodate the following five species: X. amazonica Gómez, Sääksjärvi & Veijalainen, X. guianensis Gómez & Sääksjärvi sp. n., X. jussilai Veijalainen, Sääksjärvi & Broad, X. pucallpensis Gómez & Sääksjärvi sp. n. and X. vidali Gómez sp. n. The aurita species-group, which had hitherto been regarded as the only species-group in the Neotropical region, is currently represented by five species: X. allpahuaya Gómez & Sääksjärvi sp. n., X. aurita Krieger, X. craspedoptera Krieger, X. rhabdomera Townes and X. spiloptera Krieger. The Andean species X. peruana Krieger is established as an unplaced species outside of the amazonica and aurita species-groups. A key to Neotropical species-groups and species of Xanthopimpla is provided. Xanthopimpla aurita is recorded for the first time from Ecuador and Colombia and its extensive distribution is discussed. Xanthopimpla amazonica, X. craspedoptera and X. jussilai are recorded for the first time from Brazil; X. amazonica is recorded for the first time from French Guiana; X. spiloptera is recorded for the first time from French Guiana and Peru, and X. rhabdomera is recorded for the first time from Peru.

Variation in the species richness of parasitoid wasps (Ichneumonidae: Pimplinae and Rhyssinae) across sites on different continents

“…Here we focus on two of the most extensively studied subfamilies in the Neotropical region, Pimplinae and Rhyssinae (e.g. Porter, ; Gauld, ; Gauld et al ., , ; Sääksjärvi et al ., ; Gómez et al ., , , ; Gómez & Yabar, ).…”

“…In this study, we compare observations of local species richness of pimplines and rhyssines across latitudes on the basis of field sampling we carried out in 21 sites on three continents. The two most intensively studied areas were in Peruvian Amazonia, where the sampled localities were selected so as to span different forest types (Sääksjärvi et al ., ; Gómez et al ., , ). Most sampling was done with Malaise traps, but in the two Peruvian areas, we also used other sampling methods for comparison.…”

A checklist of Pimplinae (Hymenoptera, Ichneumonidae) from the Estação Ecológica dos Caetetus in São Paulo state, with new records of Neotheronia Krieger, 1899 from Brazil

“…Recent studies show that the ichneumonid fauna of South America still contains many undescribed species (e.g., Palacio et al 2010, Valera & Días 2010, Veijalainen et al 2012, Gómez et al 2014, Gómez & Yabar-Landa 2015, Pádua et al 2015, Sääksjärvi et al 2015, Bordera et al 2016.…”

Combining Ability Effects and Inheritance of Maturity and Yield Associated Traits in F2 Populations of Wheat

“…Xanthopimpla species can be recognized by yellow body with stout legs and variables spots or black bands on abdominal tergites .Bidentate mandibles and lower teeth twisted are two characters which differentiate this genus from others (Gauld, 1984). A lot of faunal studies of this genus from different regions of the world include Thunberg (1822); Saussure (1892) and Krieger (1914) from Palearctic region; Tosquinet (1896) and Seyrig (1932) from Afrotropical region; Townes 1969 andGómez et al (2009;2014) from Neotropical regions and Townes & Chiu (1970), Gupta (1987), Pham et al (2011) from oriental regions etc.…”
