New World species of the genus Calliscelio Ashmead (Hymenoptera, Platygastridae, Scelioninae)

Abstract The genus Calliscelio Ashmead is presumed to be a diverse group of parasitoids of the eggs of crickets (Orthoptera: Gryllidae). A least one species has been found to be an important factor in depressing cricket pest populations. The New World species of Calliscelio are revised. Forty-two species are recognized, 3 are redescribed: Calliscelio bisulcatus (Kieffer), Calliscelio laticinctus Ashmead, Calliscelio rubriclavus (Ashmead), comb. n.; and 38 are described as new: Calliscelio absconditum Chen & Johnson, sp. n., Calliscelio absum Chen & Johnson, sp. n., Calliscelio alcoa Chen & Masner, sp. n., Calliscelio amadoi Chen & Johnson, sp. n., Calliscelio armila Chen & Masner, sp. n., Calliscelio bidens Chen & Masner, sp. n., Calliscelio brachys Chen & Johnson, sp. n., Calliscelio brevinotaulus Chen & Johnson, sp. n., Calliscelio brevitas Chen & Johnson, sp. n., Calliscelio carinigena Chen & Johnson, sp. n., Calliscelio crater Chen & Johnson, sp. n., Calliscelio crena Chen & Johnson, sp. n., Calliscelio eboris Chen & Johnson, sp. n., Calliscelio extenuatus Chen & Johnson, sp. n., Calliscelio flavicauda Chen & Johnson, sp. n., Calliscelio foveolatus Chen & Johnson, sp. n., Calliscelio gatineau Chen & Johnson, sp. n., Calliscelio glaber Chen & Masner, sp. n., Calliscelio granulatus Chen & Masner, sp. n., Calliscelio latifrons Chen & Johnson, sp. n., Calliscelio levis Chen & Johnson, sp. n., Calliscelio longius Chen & Johnson, sp. n., Calliscelio magnificus Chen & Masner, sp. n., Calliscelio migma Chen & Johnson, sp. n., Calliscelio minutia Chen & Johnson, sp. n., Calliscelio paraglaber Chen & Johnson, sp. n., Calliscelio pararemigio Chen & Masner, sp. n., Calliscelio prolixus Chen & Johnson, sp. n., Calliscelio punctatifrons Chen & Johnson, sp. n., Calliscelio remigio Chen & Masner, sp. n., Calliscelio ruga Chen & Johnson, sp. n., Calliscelio rugicoxa Chen & Masner, sp. n., Calliscelio sfina Chen & Johnson, sp. n., Calliscelio storea Chen & Johnson, sp. n., Calliscelio suni Chen & Johnson, sp. n., Calliscelio telum Chen & Johnson, sp. n., Calliscelio torqueo Chen & Johnson, sp. n., Calliscelio virga Chen & Johnson, sp. n. Four species are treated as junior synonyms of Calliscelio rubriclavus (Ashmead): Anteris nigriceps Ashmead, syn. n., Caloteleia marlattii Ashmead, syn. n., Caloteleia grenadensis Ashmead, syn. n., and Macroteleia ruskini Girault, syn. n.


Introduction
The genus Calliscelio Ashmead was first erected for a single species, C. laticinctus Ashmead, from the Lesser Antilles (Ashmead 1893). For nearly 80 years it was considered to be a valid genus although it remained narrowly defined. Kieffer (1926), for example, included only two species in his monograph on world Scelionidae (= Platygastridae sensu Sharkey 2007). Masner (1972) treated Calliscelio as a junior synonym of Calotelea Westwood. Shortly thereafter, though, Masner (1976) rejected this hypothesis, treated Calliscelio as valid, and also significantly expanded the extent of the genus. Kieffer had described seven other genera over the years, all of which Masner (1976) treated as junior synonyms of Calliscelio (see generic synonymy below). Recently, in a survey of external morphology across the superfamily Platygastroidea, Talamas et al. (2016) found that the prioniform sensillum on the mandible is synapomorphy for the genus Calliscelio and treated Crama Galloway, Lispoteleia Galloway, Xentor Masner and Johnson, and Yunkara Galloway as junior synonyms of Calliscelio.
The current concept of Calliscelio is a relatively large genus in the subfamily Scelioninae, comprising 77 known species (including 3 fossil species; Johnson 2016). It is a worldwide genus, with species found in all six major biogeographic regions. Interestingly, at least two species, i.e., C. rubriclavus (Ashmead) and C. elegans (Perkins), have extraordinarily broad geographic distributions possibly due to increased globalization of human commerce (Masner et al. 2009). This phenomenon leads to the question: from which part of the world did these species originate? Also, although Calliscelio was originally erected based on species in the New World, only 6 species were reported from this region to date, suggesting that more species remain to be discovered. Thus, a comprehensive revision of species of Calliscelio based on extensive sampling from the New World is needed to provide a more accurate understanding of the diversity and interrelationships among species in the genus.
Even though Calliscelio is a diverse, common, and widespread genus, the available biological data are extremely scanty. The only host record is for C. teleogrylli Hill, which was reported to attack the eggs of Teleogryllus commodus (Walker) (Orthoptera: Gryllidae), a widespread pest in pastures in the Pacific region (Hill 1983). By com-Morphological terms used in this work are as in the Hymenoptera Anatomy Ontology (Yoder et al. 2010) (Appendix 1). Identifiers (URIs) in the format HAO_XXXXXXX represent concepts in the HAO and are provided to enable readers to confirm their understanding of the concepts being referenced. To find out more about a given concept, including additional images, notes, references and other metadata, use the identifier as a search term at http://glossary.hymao.org or use the identifier as a web-link.
In the Material Examined section, the specimens studied are recorded in an abbreviated format, using unique identifiers (numbers prefixed with "OSUC", "CASENT", "UCFC", "CMNH", "MHNG") for the individual specimens. The label data for all specimens have been georeferenced and recorded in the Hymenoptera On-Line database, and details on the data associated with these specimens can be accessed at the following link, hol.osu.edu, and entering the identifier in the form (note the space between the acronym and the number). The electronic version of the paper contains hyperlinks to external resources. Insofar as possible, the external information conforms to standards developed and maintained through the organization Biodiversity Information Standards (Taxonomic Database Working Group). All new species have been prospectively registered with ZooBank (Polaszek et al. 2005, http://www.zoobank.org), and other taxonomic names, where appropriate, have been retrospectively registered.
Data associated with the genus Calliscelio can be accessed at hol.osu.edu/index. html?id=461. The generic and species descriptions were generated by an xBio:D platform application, vSysLab (vsyslab.osu.edu), designed to facilitate the production of a taxon by character data matrices, and to integrate those data with the existing taxonomic, bibliographic and specimen-level database. Data may be exported in both text format and as input files for other applications. The text output for descriptions is in the format of "Character: Character state (s)". Polymorphic characters are indicated by semicolon-separated character states.
Images and measurements were made using Combine ZP and AutoMontage extended-focus software, using JVC KY-F75U digital camera, Leica Z16 APOA microscope, and 1X objective lens. Images were post-processed with Abobe Photoshop CS3 Extended. A standard set of images is provided for each species: dorsal habitus, lateral habitus, dorsal and lateral views of the head and mesosoma, and anterior view of head. The individual images are archived in Specimage (specimage.osu.edu), the image database at The Ohio State University.
