This may be of interest to all the pleco fans.
It has been estimated than there may be hundreds of Loricariid species awaiting discovery in the streams and rivers of South America. Our good friend the explorer Heiko Bleher has discovered several previously-unknown species of Loricariid in western Brazil, Colombia and Venezuela. Photos are included. The species obviously have not yet been described and named; the "L" (for Loricariid) number is assigned to a newly-discovered species until such time as it can be scientifically described and named.
