All writers except Coquillett have overlooked the 1845 
description of Thecophora. They cite the 1857 description, 
but even so Rondani’s name is preoccupied by Charpentier’s 
use of it for a subgenus of Odonata (1840) . Since Charpen- 
tier’s name was Thecaphora a strict application of the rules 
would necessitate the use of Rondani’s Thecophora. It may 
be argued, however, that Rondani’s name is invalid since he 
did not clearly indicate a species with the genus. Thecomyia 
(Tetanoceratidse) was a slip for Thecophora.
