Western Amazonian Ateleutina ( Hymenoptera , Ichneumonidae , Cryptinae )

Ateleutina is a small subtribe of Cryptinae (Ichneumonidae) composed of two genera: Ateleute Förster and Tamaulipeca Kasparyan. Neither of the genera includes species described from South America. In this article five new species of Ateleute (A. ashaninka sp. n. and A. amarakaeri from Peru, A. shuar sp. n. from Ecuador and Peru, and A. huaorani sp. n. and A. kichua sp. n. from Ecuador) and three new species of Tamaulipeca (T. bora sp. n. from Ecuador and Peru, T. candoshi sp. n. from Ecuador and T. matses sp. n. from Peru) are described and illustrated from Western Amazonia. Identification keys to the known South American species of the genera are provided.

Despite the fact that recent molecular studies discourage the use of the traditional Cryptinae subtribes of Townes (Laurenne et al. 2006), since the most part of them are not monophyletic groups, no new classification of genera has been proposed.In accordance, we consider Ateleutina sensu Townes as a framework for the present study.
Ateleute is a nearly cosmopolitan genus with 35 described species.A large part of the species are tropical in distribution: 24 are Ethiopian, 3 Palearctic, 1 Nearctic and Neotropical, 2 Neotropical and 5 Oriental (Yu et al. 2005, Sheng et al. 2011).Tamaulipeca comprises only two described species from Mexico and Costa Rica (Kasparyan and Hernández 2000).
The distribution of Ateleutina is interesting, as no species have been described from South America despite most of the Ateleute species being tropical in the Old World.However, already Townes (1967) mentioned having seen three undescribed species of Ateleute from Peru.
Almost nothing is known about the biology of Ateleutina.Townes (1967) reported that A. carolina Townes was reared several times from a psychid (Lepidoptera: Psychidae).
In several sampling programs collecting parasitoid wasps, carried out in Western Amazonia, we have found eight new species of Ateleute and Tamaulipeca.The aim of the present paper is to describe and illustrate all of them and to provide an identification key for these South American species.

Material and methods
The Peruvian specimens were collected mainly in the course of two projects.The sampling program coordinated by S. Bordera and A. Rodríguez-Berrío was carried out from February 2008 to February 2009 in three Peruvian ecosystems: 1) the coastal valleys of  and Huaral (400-900 m), located in the central part of the coastal desert; 2) the central Andes in El Ingenio (Huancayo,3,200 m); and 3) premontane tropical rain forest in the "Fundo Genova", Chanchamayo, Department of Junín (1,066-1,080 m).In this project Ateleutina were found only in Fundo Genova Trap 2. (11°05'44.8"S,75°21'17.7"W,1069 m) and Trap 4. (11°05'45.1"S,75°21 '21.8"W, 1075 m.).More information about the vegetation and climate of the area is given in Alvarado et al. (2011).
The second Peruvian sampling program was coordinated by I. Sääksjärvi in the 56,000 ha National Reserve of Allpahuayo-Mishana, approximately 3°57'S, 73°16'W (e.g.Sääksjärvi et al. 2004).The reserve is located about 25 km south of Iquitos in the Department of Loreto.The area is primarily moist tropical forest.General descriptions of the climate, geology and vegetation of the area are given in Kalliola and Flores Paitán (1998).
Specimens from Southern Peruvian Amazonia were also collected by Malaise trapping in Madre de Dios, by Isrrael Gómez (ZMUT).The study site is located near the Manu National Park.
Ecuadorian specimens were collected by canopy fogging in Onkone Gare, Department of Orellana, Ecuador, by Dr. Terry Erwin (USNM).The study site is located near the border of the Yasuní National Park.
The specimens are deposited in the following collections: Entomological Collection, University of Alicante, CIBIO, Spain (CEUA), Entomological Museum Klaus Raven Büller, Universidad Nacional Agraria la Molina, Lima, Peru (MEKRB), Smithsonian Institution, USA (USNM), University of San Marcos, Lima, Peru (UNSM) and The Zoological Museum, Section of Biodiversity and Environmental Research, Department of Biology, University of Turku, Finland (ZMUT).The specimens deposited at the USNM and UNSM are currently on loan to the ZMUT.
Observations were made using Olympus SZX10, Olympus SZX16, and Wild M3Z stereomicroscopes.Layer photos were taken in ZMUT using an Olympus SZX16 attached to an Olympus E520 digital camera.Digital photos were combined using the programs Deep Focus 3.1 and QuickPHOTO CAMERA 2.3.The SEMimages were taken using a Hitachi S-3000N scanning electron microscope (in low vacuum mode) in the University of Alicante, Spain.Morphological terminology follows Gauld (1991).

Results
Despite the large sampling effort (e.g.300 Malaise trap months in different Peruvian ecosystems), only 16 females and 9 males belonging to Ateleutina were collected, all of them from moist tropical forests.
The females and males we have found in the field differ greatly from each other in all localities.The females of all species are coloured red, brown, black and white, while all males are uniformly brown or black in coloration (Figs 2A-E; 8A-D).
In Ateleute we have been able to put forward a proposal of sexual associations based on external morphological characters, but for Tamaulipeca we have not been able to link the only male to any of the females, therefore a description and illustration of this specimen is provided without assigning it to any of the species.
