Dear all,<br>
<br>
<br>
<p>Has someone (or is interested in) created an IUCN case to
suppress Philhelius Stephens, 1841:201 in favour of Xanthogramma
Schiner, 1860:215 ?</p>
<p><br>
</p>
<p>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.<br>
</p>
<p>In Dipterists Digest 2018 there is a personal comment of Martin
Speight that "replacing the well-established generic name
Xanthogramma by<br>
Philhelius Stephens serves no useful scientific purpose and simply
introduces confusion"</p>
<p><br>
</p>
<p>The confusion has arrived as GBIF which is using Systema
Dipterorum as source, and any website using GBIF data are taking
over the synonym. </p>
<p><br>
</p>
<p>Time for action?</p>
<p>I am willing to file the case but may need some help in
formulating it correctly.</p>
<p><br>
</p>
<p>Cheers,</p>
<p>Bastiaan<br>
