Specimens
There are only two specimens of this spider in existing collections. Although multiple specimens were reported to have been collected, only two exist in collections; the rest were reported lost in transit when the co-discoverer, Ingi Agnarsson, brought his research materials from University of Puerto Rico to University of Vermont. The two specimens which remain were partially destroyed for DNA barcoding.
