Taxonomic Decision for Synonymy

• Irwin, M.E. & Lyneborg, L. 1989. Family Therevidae. pp. 353-358 in Evenhuis, N.L. (ed.). Catalog of the Diptera of the Australasian and Oceanian Regions. Honolulu and Leiden : Bishop Museum Press and E.J. Brill 1155 pp. [357] (Irwin & Lyneborg (1989) erected the name Johnmannia citing preoccupation of the name Mannia by Dewalque (1868). However, the Dewalque name for a fossil had been declared a nomen nudum (Neave 1940). The name Mannia was preoccupied by Davidson (1874) for a fossil brachiopod, and again by Prout (1915) for a moth (Lambkin et al. 2005: 9))

Introduction

Johnmannia contains unusual, large therevids with glossy black integument reflecting blues and greens and an unusually globular appearance as the abdomen is curved beneath the body. The very rarely collected Johnmannia have only been found in closed wet sclerophyll forests and rainforests, an atypical niche in the Australian environment for the Family Therevidae. None of the three species is known from more than 10 specimens (Lambkin et al. 2005).
