Bengaliidae Du Monde (Insecta: Diptera)

About this book

Language: French with English summary

This monograph reveals spectacular and previously unknown, taxonomic diversity of the new myrmecophilous dipteran family Bengaliidae. The type and sole genus, Bengalia, has hitherto been placed in the family Calliphoridae. Based on a thorough revision and a detailed study of its morphology, Bengaliidae is shown to represent a distinct family phylogenetically distant from Calliphoridae. The new family actually comprises four subfamilies, 12 genera and 70 species, of which three subfamilies, ten genera and 49 species are described as new. All Bengaliidae appear to be associated with ant nests in the Afrotropical and Oriental regions. The monograph is richly illustrated, giving in detail the characters of, and keys to, all the taxa of Bengaliidae. The male genitalia are depicted for each of the new or revised species. The phylogeny of Bengaliidae and its position within Diptera is also discussed.
