Etymology: Named for Dr. Mark Henry Sabaj, Collection Manager of Ichthyology, ZOOTAXA
Academy of Natural Sciences of Philadelphia, for his tremendous help in collecting specimens
throughout South America, and because he collected the first live specimen that I
ever saw. Pronounced sah-bay’-i.
Discussion
Some variation was found in PCA among the three populations (Fig. 6, most strongly
weighted characters shown along axes); however, there are far too few collections available
at this time to determine if these morphometric differences represent interspecific differences.
Color and meristics did not vary significantly among populations. Type
specimens were restricted to the Essequibo River drainage because future effort might
determine that the three known populations (Essequibo, Negro, Orinoco) should be separated.
