Etymology: adenacanthus: The specific epithet is derived from the Greek adenos, meaning gland, and akanthos, meaning spine, in reference to the restriction of the glandular tissue to the area where the anal-fin spines are located.

ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 10; ຄີກົ້ນຂອງປາ: 22 - 27; ສັດທີ່ມີກະດູກສັນຫຼັງ: 37 - 39. Phallobrycon and Bryconadenos are the only members of the Clade A characids that possess a combination of intumescent glandular tissue present on the anterior part of the anal fin and pelvic-fin hooks absent in sexually mature males. This species can be diagnosed by the following characters: the glandular tissue is associated with specially developed spines on some anal-fin rays. Two developed spines are present on median unbranched portions of fifth, sixth and seventh anal-fin rays which are larger and separated from the close-set smaller hooks that appear on distal portions of the anterior anal-fin rays of Phallobrycon, and different from those found on distal portions of several anal-fin rays of many characids. Large spines and small hooks are never found together on any anal-fin ray in Phallobrycon; presence of a simple concentration of glandular tissue on the anterior part of the anal fin; and presence of a developed urogenital papilla in male specimens (Ref. 81937).
Found in the main channel of rivers with fast flowing and rather shallow clear waters, with abundance of rocks and thick sand (Ref. 81937).
