[Syrphidae] Suppress Philhelius in order to keep using Xanthogramma

[Bastiaan Wakkie]

Dear all,


Has someone (or is interested in) created an IUCN case to suppress 
Philhelius Stephens, 1841:201 in favour of Xanthogramma Schiner, 1860:215 ?


Evenhuis 2018, created a new synonym for Xanthogramma based on his 
research on Daniel William Coquillett's work but mentions while creating 
the synonym that suppression may be warranted in case the synonym would 
be a threat to stability.

In Dipterists Digest 2018 there is a personal comment of Martin Speight 
that "replacing the well-established generic name Xanthogramma by
Philhelius Stephens serves no useful scientific purpose and simply 
introduces confusion"


The confusion has arrived as GBIF which is using Systema Dipterorum as 
source, and any website using GBIF data are taking over the synonym.


Time for action?

I am willing to file the case but may need some help in formulating it 
correctly.


Cheers,

Bastiaan
