Doesn't help much at all. I'm leaning torwards S. Altuvie (due to the lack of spotting below the lateral line) or S. Rhombeus. The Rhombeus family is so diverse based on geographical collection point, having one rhomb that doesn't look like your others is not that uncommon. A collection point would be very helpful (especially since Altuvies are only native to Venezuala). Without the full flank shot, I can't be any more certain than that.
