 Notes: This name has recently been cited as a synonym of Ischnopoda, on 

 the assumption that they are isogenotypic. In the present study it is 

 believed to be an error to claim that Westwood's designation of aterrima 

 Gravenhorst as type of Ischnopoda makes atra Gravenhorst the true type. 

 If Westwood's designation is taken literally, as I believe it must be, then 

 the name Ischnopoda must be applied to a very different genus and 

 Tachyusa is the oldest of the names remaining for the genus which 

 includes atra.
