Introduction

Viereck, 1912 is a moderately large genus of spider-attacking Darwin wasps. It is confined to the New World where it occurs from Mexico and Central America to Southern Brazil (Gauld 1991; Kumagai and Graf 2002; Yu et al. 2012; Pádua et al. 2015).

The species of are known to be koinobiont ectoparasitoids attacking sub-adult and adult orb-web-spinning spiders belonging to the families and (summarised in Pádua et al. 2016). is closely related to Townes and Gauld and it can be easily separated from these two genera by possessing a pocket-like structure on the mediodorsal part of the pronotum (Gauld 1991).

Currently, there are 20 described species in the genus (Yu et al. 2012; Pádua et al. 2015) and the majority of them have been discovered from Brazil (Brullé 1846; Kriechbaumer 1890; Loffredo and Penteado-Dias 2009; Sobczak et al. 2009; Pádua et al. 2015) and Central America (see Cresson 1865; Brues and Richardson 1913; Townes and Townes 1966; Gauld 1991, 2000). Very little is known about the occurrence of the genus in other Latin American countries. The main aim of this work is to describe seven new species of from Peru, French Guiana and Ecuador. In addition, we provide new faunistic records for the genus and an illustrated identification key to all species.

Materials and methods

The specimens studied in this work are deposited at the Florida State Collection of Arthropods (), Gainesville, USA, The Natural History Museum, University of San Marcos (), Lima, Peru, The Natural History Museum, London, UK (), and the Biodiversity Unit, Zoological Museum, University of Turku (), Turku, Finland. The specimens of MUSM are currently on loan in ZMUT.

Specimens were examined with an Olympus SZ61 and SZX10 stereomicroscopes and measurements were made through a millimetre ocular. Digital layer images were taken using a Canon DS126461 digital camera attached to an Olympus SZX16 stereomicroscope and combined by using the software Zerene Stacker (Version 1.04 Build T201706041920). Drawings were vectorized digitally using Adobe Illustrator.

The morphological terminology and style of descriptions follow those of Pádua et al. (2015). In this study, the measures and proportions between the structures are given as the value of the holotype [in brackets], followed by the minimum and maximum number of variations. The new country records of the genus are marked with a double asterisk and new country records of the species were marked with a single asterisk. The maps were produced through the website Simplemappr (https://www.simplemappr.net).

Comments.

According to Gauld (1991, 2000) is very similar with the sister genus Townes, 1960. They both have the occipital carina strongly raised (flange-like) and projecting posteriorly to surround the anterior reflexed end of the pronotum; head rounded with the genae strongly narrowed from the eyes to the occipital flange; and the pronotum unusually elongated, with a long horizontal part mediodorsally. It differs from by having a unique forwardly directed pocket-like structure on the pronotum mediodorsally.

Discussion

The present study increases the number of recognized species to 27 species. In addition, is presented a large amount of faunistic records from different parts of Central and South America. It is also shown that sp. nov. belongs to the species group (Pádua et al. 2015) which is characterised by the following set of characters: 1) face sculptured below the insertion of antennae, with a longitudinal carina in the middle part of the face; 2) head with occipital carina projected, not curved upwards, with a dorsal concavity in the apex; 3) pronotum with the pocket-like structure reduced longitudinally; 4) sternite I with a ventral spine-like projection posteriorly. After the present study this species group is composed of five species (, , , sp. nov., and ),

A noteworthy new character state was recorded for : in sp. nov., the epicnemial carina is ventrally present and extending to the level of the lower lateral corner of the pronotum. This character state is shared with most species of (Pádua et al. 2020), and likely represents a homoplastic trait in the two genera.

Finally, the genus is reported for the first time from the Andes (Figs 107, 108). Two Peruvian species, both collected by Carol Castillo, were found from the Andean-Amazonian interface (Cusco, San Pedro, Cosñipata valley, 1302–1520 m). sp. nov. and sp. nov. are both remarkable because they resemble Gravenhorst (and Palacio, Broad, Sääksjärvi & Veijalainen, 2010) by the shape of the occiput. All other species of have the occipital carina strongly raised and produced into a neck-like structure.
