Ichthyologist Nathan Lujan and his crew just published a set of photos from a recent Guyana expedition. One of the species they found was Ivanacara bimaculata, a fish not seen many times before. I have only seen pics of this species once before, those fish belonged to Vermeulen in Holland but were all females I think. As far as I know, no-one has collected them since.
