Procatopus nototaenia is the most likely suspect as these are the most common,
Its definately a Procatopus sp.
Either Nototaenia, Aberrans or Similis.
There are many different collection locations for each, and they all have slightly different colour patterns. I personall have never kept this genus of killi. but I would err on the side of Procatopus nototaenia.
