Open Access



The wasp subfamilies Amiseginae and Loboscelidiinae (Hymenoptera: Chrysididae) were last catalogued in Kimsey and Bohart (1991). The subfamilies are considered to be obligate egg parasitoids of the Phasmida (stick insects), which are known to be pests in many areas of the world (Baker 2015). Our lack of knowledge of these wasps, in particular their host associations and host specificity, prevents studies into using them as potential control agents for pest phasmids. Phasmids are popular throughout the world with people from a wide range of backgrounds, from pet keepers to professional entomologists.

New information

A taxonomic database of the subfamilies Amiseginae and Loboscelidiinae has been created as the Chrysididae SpeciesFile, summarising the current state of scientific knowledge about these groups. In addition, a bibliography of works on these subfamilies has been created. In total information is provided for 187 valid species.

The Phasmida Species File Online (Brock 2015) has become the defacto online resource for reliable taxonomic information on that order. It is hoped that a creation of a similar database of their predominant egg parasitoids will facilitate new research in this field. The host associations of the Amiseginae and Loboscelidiinae are poorly known. Only 12 unique associations at the species level have been recovered from the literature while developing the current project.

The Phasmida (= Phasmatodea; Phasmatoptera; Cheleutoptera) are large, obligate herbivores (Bedford 1978) that are known as pests of agriculture and forestry in North America, Asia, and Oceania (Baker 2015). The wasp subfamilies Amiseginae and Loboscelidiinae are believed to be obligate parasitoids of phasmid eggs (Krombein 1983), and as such, they have potential for the biological control of phasmid outbreaks and infestations. Our knowledge of host preference and host specificity is currently insufficient, and further work is required to establish the feasibility of these wasps as control agents.

The rate at which this knowledge is acquired could be increased if studies were made by the large number of people interested in phasmids, from pet keepers through to professional taxonomists. It is hoped that by making knowledge of these enigmatic wasp species freely available online that further research on these groups is encouraged, both by hymenopterists and phasmatologists.

General description


The last comprehensive species catalogue of the Amiseginae and Loboscelidiinae was published in Kimsey and Bohart (1991). The database presented here draws heavily on this work, and brings it up to date through the incorporation of information from subsequent publications and online presentation. Summary statistics are provided in Table 1.

The publication of this data paper is intended not only to publicise the online database, but also to provide a convenient method of citation. The Phasmida Species File Online (Brock 2015) has been cited as a website in multiple fashions with varying dates of ‘publication’. A data paper (Chavan and Penev 2011) provides a single method of citation, complete with a Digital Object Identifier (DOI).

Additional information: 

The Chrysididae SpeciesFile was created by entering the Amiseginae and Loboscelidiinae data provided in Kimsey and Bohart (1991) to create an initial taxonomic hierarchy. Original references were then checked for additional information, and Google Scholar was used to identify publications since 1991. The references of all publications used were checked for additional sources of information. Notes next to references that contain keys and images are made on individual species pages.

Geographic coverage


The database has global coverage of the two subfamilies, the combined distribution of all taxa covered is shown in Fig. 1

Taxonomic coverage


The database contains records of all known valid species of Amiseginae and Loboscelidiinae, with full details of synonymy within these subfamilies, both recent and fossil. Full details are given for all type specimens, type species and the first usage of family-group names Fig. 2. Additional specimens from collections have been added from the literature to provide fuller coverage of biogeography.

Data Sharing

The use of the SpeciesFile software allows for sharing taxonomic data with Species2000/Catalogue of Life, and specimen data with the Global Biodiversity Informatics Facility (GBIF). This is achieved through the DarwinCore Archive format, which has become the standard format for sharing biodiversity realted datasets (e.g. Baker et al. 2014) and build on the DarwinCore standard (Wieczorek et al. 2012). The Chrysididae Species File DarwinCore Archive can be downloaded from Baker 2015b.


The species file will be maintained by the author, who will gratefully receive any new papers on these subfamilies via e-mail. At present there are no plans to include the other subfamilies of Chrysididae (Chrysidinae and Cleptinae) unless appropriate editors volunteer their services.


Marilyn Beckman (Species File Software Group, Illinois Natural History Survey) has provided a great deal of assistance in getting the Chrysididae SpeciesFile set up and running.

Philippa Richardson (University College London) provided feedback on the manuscript. I would like to thank the editor and reviewers for their constructive comments on the manuscript.
