It was posted on 17 December 2010 at these websites as Stiliger sp. A Genus: Ehrenberg, 1831,
and on 15 August 2011 changed into Stiliger sp. 01 Genus: Ehrenberg, 1831.
For some genera, such as Trinchesia was the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I had chosen 2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
The sacoglossa expert Kathe R. Jensen still considers this species to be a Costasiella.(Pers. comment on 17 June 2018).
