E-mail: isrrael.gomez@yahoo.com 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.

Introduction The parasitoid wasp family Ichneumonidae is one of the most species rich components of insect life in most terrestrial ecosystems (Gauld 1991; Sääksjärvi et al. 2004). However, only a few detailed ichneumonid inventories have been conducted in rainforests of the Neotropical region. In this region, most studies have concentrated on Central America, in particular Costa Rica, where the late Ian D. Gauld with his collaborators monographed many of the subfamilies (Gauld 1988; 1991; 2000; Gauld et al. 1997; 1998; 2002). These revisionary works hugely improved our knowledge of the Neotropical fauna. Although the South American ichneumonid fauna is generally far more poorly known than the Central American fauna, over the last 15 years, some highly diverse regions of western South America have been sampled in more detail. Sampling has mainly concentrated on the tropical Andes (e.g. Palacio et al. 2007; Castillo et al. 2011) and Western Amazonian areas (e.g. Sääksjärvi et al. 2003; 2004; Gómez et al. 2009; Palacio et al. 2010; Broad et al. 2011). These studies have revealed a plethora of new species and genera from the Andean and Amazonian interface. Based on this evidence, and considering that most of the Neotropical region is still poorly studied for parasitoids, the ichneumonid fauna in this region is certainly one of the richest on Earth. Following the taxonomic work of, especially, Gauld (Gauld 1991; Gauld et al., 1998; 2002) and Charles Porter (Porter 1970 a,b) the ichneumonid subfamily Pimplinae is now one of the best-known groups of the family in the Neotropical region. Species of Xanthopimpla Saussure are among the most conspicuous and abundant tropical components of pimplines, predominantly bright yellow, moderately large and rather easily defined and recognized by several reliable morphological characters. For a long time this genus has caught the attention of various entomologists (e.g. Thunberg 1822; Saussure 1892; Tosquinet 1896; Krieger 1899; Krieger 1914; Townes 1969; Townes & Chiu 1970; Gómez et al. 2009, Pham et al. 2011) becoming to date the most species-rich pimpline genus and one of the best studied genera of the family Ichneumonidae. Xanthopimpla species are idiobiont endoparasitoids of Lepidoptera pupae (Gauld 1991). For this reason, several species have been utilized in biological control of economically important agricultural pests (Hailemichael et al. 1994; Gitau et al. 2007; Dum et al. 2011). Many species are abundant in tropical areas, especially in tropical Asia where most of the species occur (Townes & Chiu 1970; Pham et al. 2011). Surprisingly, only a few Xanthopimpla species have been described from the Neotropical region (Townes 1969; Gómez et al. 2009). It is, however, important to consider that many tropical pimplines are hard to collect even during long-term field inventories (Sääksjärvi et al. 2004) and the rare species usually remain undiscovered by short-term sampling. The aim of the present work is to revise the Neotropical Xanthopimpla. We describe four new species and define a new species-group to accommodate several South American species which cannot be accommodated within any of the numerous existing species-groups (most of which are strictly Old World). In addition, we illustrate and provide identification keys to the Neotropical species-groups and species. Material and methods This study is based mainly on the ichneumonid samples collected during our long-term western Amazonian ichneumonid survey in the years 1998, 2000 (Sääksjärvi et al. 2004), 2008 (Gómez et al. 2009) and 2011 (unpublished data). During this survey we have utilized different sampling methods (mainly Malaise trapping but also sweep netting, rearing, light trapping and yellow pan trapping) in Allpahuayo-Mishana National Reserve (Department of Loreto, Peru) and in Los Amigos Conservation concession (Department of Madre de Dios, Peru). However, Malaise trapping has been the only successful method in sampling Xanthopimpla. In addition, we have studied a large number of samples collected by canopy fogging in Ecuadorean Amazonia (by Terry Erwin and his team) and Malaise samples collected in tropical Andean forests (Castillo et al. 2011). Over the last few years we have also studied a large number of Malaise samples collected from the tropical forests of French Guiana (by the Société Entomologique Antilles Guyane (SEAG) team; ichneumonid samples coordinated by Yves Braet) and Central America (LLAMA project, led by John Longino). We have also studied a number of specimens deposited in the Instituto Nacional de Pesquisas da Amazônia, Brazil (INPA) and the Museu de Zoologia da Universidade de São Paulo, Brazil (MZUSP). 58 Zootaxa 3774 (1) 2014 Magnolia Press GÓMEZ ET AL.
In addition to the extensive new material listed above, we studied the Neotropical specimens of Xanthopimpla deposited in the Natural History Museum, London, UK (BMNH) and the Swedish Museum of Natural History, Stockholm, Sweden (NHRS). Paratypes of X. rhabdomera Townes deposited in the Canadian National Collection of Insects (CNC) were studied using photos provided by Andrew Bennet. Morphological terminology and style of descriptions follow Gauld (1991) and Gómez et al. (2009). The identification key for the aurita species-group is modified from that of Gómez et al. (2009). Specimens are deposited in the following collections: the Zoological Museum, Section of Biodiversity and Environmental Science, Department of Biology, University of Turku, Finland (ZMUT); the Smithsonian Institution, Washington, DC, USA (NMNH); the Natural History Museum, University of San Marcos, Lima, Peru (UNSM); and the Instituto Nacional de Pesquisas da Amazônia, Brazil (INPA). All observations were made using Olympus SZX10 and SZ40 stereomicroscopes. Digital photos were taken using an Olympus SZX16 stereomicroscope attached to an Olympus E520 digital camera and combined using the software Deep Focus 3.1 and Quick PHOTO CAMERA 2.3. Taxonomy The following keys work best for females. Males of many species are unknown. For this reason, the identification of male specimens should always be confirmed by comparing them to female specimens and descriptions. A few specimens of many Neotropical species have dark-marked metasoma 5 +; identification of these specimens is more difficult and all characters should be checked.

The amazonica species-group can be distinguished from all other New and Old world species-groups of Xanthopimpla by the combination of the following characters: 1) occipital carina developed into a thin, high flange (Fig. 1b); 2) propodeal spiracle joined to the pleural carina by a short carina (Fig. 1e); and 3) first tergite with lateromedian carinae anteriorly highly elevated (Fig. 1h). At least the first two characters seem to be unique to the amazonica species-group. Remarks. The species of the group are restricted to South America and have been found mainly in the vast Amazonian lowland rainforest area (Fig. 8). All species are rare and we have only seen a few specimens. Xanthopimpla amazonica Gómez, Sääksjärvi & Veijalainen 2009 (Figs. 2a, 3a, 4a) Original description. See Gómez et al. (2009). Diagnosis. This species can be distinguished from all other Neotropical Xanthopimpla by the combination of the following characters: 1) occipital carina complete and expanded into a high thin flange; 2) propodeum with petiolar area divided by a longitudinal carina that starts in the center of the posterior transverse carina; 3) posterior transverse carina bowed in the center; and 4) ovipositor sheath about 0.8 1.1 times the length of the hind tibia.

Anterior and posterior margins of mesopleuron narrowly infuscate; hind coxa ventrally black marked; ovipositor sheath proximally yellowish, strongly infuscate distally. Wings slightly yellowish, pterostigma brownish. Male: Similar to female. Diagnosis. This species can be distinguished from all other Neotropical species of Xanthopimpla by the combination of the following characters: 1) metasoma and hind leg without black marks; 2) propodeum with anterior transverse carina absent centrally; 3) lateromedian longitudinal carinae only present anteriorly (area superomedia not defined laterally); 4) ovipositor sheath about 0.5 0.6 times as long as hind tibia, yellowish but apically infuscate; and 5) occipital carina dorsally absent. Xanthopimpla allpahuaya sp. n. resembles X. aurita especially in propodeal carination. However, this new species has a longer tergite 1, has no black marks on the metasoma and the ovipositor sheath is about half the length of that of X. aurita. Biological notes. This species appears to be restricted to highly vulnerable white sand rain forests (varillal forests). Etymology. The specific name refers to the Allpahuayo-Mishana National Reserve, Department of Loreto, Peru, the principal Peruvian fieldwork area of the first and second authors. This species is named in honour of this unique area of Peruvian Amazonia. Distribution. Brazil, Ecuador, Peru. FIGURE 5.

The Andean species X. peruana is established as an unplaced species outside of the aurita and amazonica species-groups. It may be possible to place it into a new species-group in the future after the tropical Andes become better sampled. Distribution. Ecuador, Peru. New material examined.

Male (ZMUT): as above but IX.2007. Notes. The species seems to be the only Neotropical Xanthopimpla restricted to the tropical Andes at about 1200 1500 m above sea level. Discussion The study of Neotropical Xanthopimpla was initiated by Krieger (1914) when he described the first species from the region. Later, Townes (1969) revised the Neotropical Xanthopimpla and described a new species from Brazil, X. rhabdomera. From the limited material available Townes placed all the Neotropical Xanthopimpla species known to him in a single group, the endemic aurita species-group. Recently, Gómez et al. (2009) suggested that there may be more species-groups in the Neotropical region. In the present study, after an examination of all the described and previously undescribed Neotropical species, we define a new species-group and establish one unplaced species which potentially will form a new species-group in the future.

Distribution and species-richness. In the Neotropical region, the genus Xanthopimpla is currently represented by 11 species belonging to two species-groups and one unplaced species. The amazonica speciesgroup seems to be endemic to northern tropical South America, especially Amazonia. To date, the species of this group have only been found in lowland areas. The aurita species-group is widely distributed across the whole Neotropical region; most of the species have extensive ranges and they have been found at elevations ranging from 0 to about 1600 m. The unplaced X. peruana seems to be restricted to the tropical Andes at elevations ranging from 1200 to about 1600 m. The distribution of the species in the Neotropical region is illustrated in Fig. 8. All the Neotropical Xanthopimpla are present in South America and only two species, X. aurita and X. craspedoptera, are also found in Central America. It appears that the Neotropical Xanthopimpla reach their peak species-richness in Peru with nine of the 11 described species occurring there. However, it has to be taken into account that during the last decade the Peruvian fauna of Ichneumonidae has been studied more intensively in comparison with many other Neotropical countries (e.g. Sääksjärvi et al. 2004; Gómez et al. 2009). Most probably, Xanthopimpla species are wide-spread in the Neotropical region and further sampling in other countries may yield a similar species-richness as found in Peru. Xanthopimpla is primarily a tropical lowland genus. All described Neotropical and Old World species have been found at elevations no higher than 1800 m. In the Neotropical region only X. peruana seems to inhabit exclusively mid altitudes above 1200 m. The vast lowland Amazonian region seems to provide favorable conditions for the diversification of Xanthopimpla in South America. Nevertheless, the number of Xanthopimpla species described from the Neotropical region is only about five per cent of those described from tropical Asia which seems to reflect the Old World biogeographical origin of the genus. Xanthopimpla is the most species-rich pimpline genus. Recently, Pham et al. (2011) described 14 new species from Vietnam. Currently, with the four new species described here, the total number of described species is 265. Most probably the final number of Xanthopimpla species will be much higher as the ichneumonid fauna of most tropical areas (especially the Amazon basin and Congo basin) have only been sampled superficially. The status of the widely distributed Xanthopimpla aurita. Xanthopimpla aurita is the predominant Neotropical species of the genus. Its geographical range is broad and extends from northern Mexico to southern Brazil (Gauld 1991), and from sea level up to about 1300 m. This species is abundant in our Peruvian Amazonian Malaise trap samples (we have collected more than 120 specimens belonging to this species). In addition, we examined specimens from Brazil, Colombia, Costa Rica and Ecuador (deposited in BMHN, INPA, MZUSP and NHRS). In this material, most of the South American specimens agree well with the re-description by Townes (1969), but differ to some degree from that made by Gauld (1991) who examined material mainly from Costa Rica. In Gauld s re-description the specimens are described as having all tergites with black bands (Fig. 5b) whereas in most of the South American specimens only the first tergite possesses a black band. In addition, the ovipositor seems to be longer in South American specimens (ovipositor sheath hind tibia ratio being 1.0 1.2 in South America and 0.8 1.1 in Costa Rica). Gauld (1991) also commented that the material examined by him was limited and because of this it was hard to formulate clear conclusions about the intraspecific variation of this species. There are a few Brazilian specimens with similar metasomal coloration to the Costa Rican specimens. There is also some variation in the fore wing color, with a more yellowish tinge in some Amazonian specimens. Despite this variation we regard all the specimens as belonging to X. aurita confirming the wide distributional range of the species proposed by Gauld (1991). The varying coloration of the species might depend on e.g. different mimicry complexes in the Central and South American parts of its range. However, further morphological and molecular studies are clearly needed to resolve the status of this species in the Neotropical region.
