Fig. 1 in Putative relationships among inseminating and externally fertilizing characids, with a description of a new genus and species of Brazilian inseminating fish bearing an anal-fin gland in males (Characiformes: Characidae)

Fig. 1. Bryconadenos tanaothoros, two live adult male specimens in aquaria. Originally collected in Brazil: Mato Grosso; tributary to rio Suiazinho near Ribeirão Cascalheira. The reflective green shown especially by the lower specimen of the two sexually active males displays only weakly this color of the body sides. The position of the anal-fin gland can be seen as a pale gray-white oval area just posterior to the proximal end of the white pigment along the anterior border of the anal fin, especially in the upper male in the picture. Both males display the lateral-line pores and tubes outlined in black as occurs in live specimens.
