The taxonomy of the subfamily Cheloninae (Hymenoptera: Braconidae) was studied in Egypt. It includes 16 species belonging to two tribes (Chelonini and Phanerotomini) and three genera (Ascogaster Wesmael, Chelonus Panzer and
Phanerotoma Wesmael), of these five species are new recorded for the first time from Egypt and two (Phanerotoma (Bracotritoma) ponti sp.n. and Phanerotoma (Phanerotoma) elbaiensis sp.n.) are new for science.
The diagnostic characters of the different taxa under study (subfamily, tribes and genera) are given in brief. Keys are constructed to separate between species of each genus. All the species under consideration are fully described; this is accompanied with illustrations to the most important taxonomic characters.
Faunistic data of the 16 studies Cheloninae species are given. A zoogeographical characterization of each species is proposed.

Zusammenfassung der Kapitel (Chapter Summaries)
The first chapter delves into the taxonomy of Cheloninae in Egypt, encompassing three genera: Chelonus, Phanerotoma, and Ascogaster. The chapter includes detailed descriptions of each species, along with illustrations of significant taxonomic features. The second chapter focuses on a faunistic study of Cheloninae in Egypt, analyzing the zoogeographical distribution of the species across different geomorphological regions. The study emphasizes the importance of cultivated areas for Cheloninae diversity, while highlighting the lower species richness in desert regions.

Frequently Asked Questions
What are Cheloninae?
Cheloninae is a subfamily of braconid wasps (Hymenoptera: Braconidae) that act as parasitoids of other insects.
How many species of Cheloninae were identified in Egypt?
The study identifies 16 species belonging to two tribes (Chelonini and Phanerotomini) and three genera (Ascogaster, Chelonus, and Phanerotoma).
Were any new species discovered in this study?
Yes, two species are new to science: Phanerotoma ponti and Phanerotoma elbaiensis. Additionally, five species were recorded in Egypt for the first time.
What is the zoogeographical distribution of these wasps in Egypt?
The study provides faunistic data and zoogeographical characterization, showing that species richness is higher in cultivated areas compared to desert regions.
Are there keys for identifying these species?
Yes, the study includes constructed keys to separate tribes, genera, subgenera, and individual species, accompanied by illustrations of taxonomic characters.
