A second species of inseminating tetra in the genus Bryconadenos has been named after notable ichthyologist Stanley Weitzman.
Publishing the description of Bryconadenos weitzmani in a recent issue of the journal Neotropical Ichthyology, Narcio Menezes, Andr Netto-Ferreira and Katiane Ferreira distinguish the new species from its only congener, B. tanaothoros, by the presence of a conspicuous dark blotch at the humeral region, fewer scale rows (7"8) between the dorsal-fin and anal-fin origin and a cup-shaped anal-fin gland in mature males, with its lower part much more developed than the upper.
Bryconadenos weitzmani is known from the Curu River in the Xingu River drainage.
The fish were found living in clear water rocky rapids, with thick sand on the bottom, and observed to form small schools of about 10"15 individuals actively swimming against fast-flowing water.
