Hemibrycon paez Román-Valencia & Arcila-Mesa, 2010

Description


Dorsal soft rays (total): 9 - 10; Vertebrae: 40 - 41. Can be diagnosed in having the following characters: lateral line scales 39-42 (vs. 43-54; except 34-35 in Hemibrycon orcesi); scales between lateral line and anal-fin origin 6-7 (vs. 4-5; except 7-9 in Hemibrycon colombianus); and scales between lateral line and dorsal-fin origin 6-7 (vs. 8; except 7-10 in Hemibrycon colombianus). Most specimens of Hemibrycon paez differ from those of Hemibrycon boquiae, Hemibrycon yacopiae and Hemibrycon raqueliae by the possession of 19-23 anal-fin rays (vs. 23-29); readily distinguished from its congeners by having the mesopterygoid barely touching the metapterygoid (vs. overlapping the metapterygoid, except in Hemibrycon jabonero, Hemibrycon rafaelense and Hemibrycon guppyi) (Ref. 83529).
