Hi Scott,
<div class=""><br class="">
</div>
<div class="">these are indeed unwanted duplications of species in our backbone. The software that builds the backbone so far does not yet try to synonymize these spelling variations automatically as it is quite easy to get that wrong. We will work on this
in an improved version of the algorithm, the open issue is here:</div>
<div class=""><a href="http://dev.gbif.org/issues/browse/POR-2812" class="">http://dev.gbif.org/issues/browse/POR-2812</a></div>
<div class=""><br class="">
</div>
<div class="">… which is part of the next round of improving the backbone building:</div>

<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Until then please let us know about those duplicate names. It helps understanding the problem better and as a last resort we could add those names to our patch list as known spelling variations, i.e. synonyms. They then get synonymized in future
backbone versions:</div>
