背棘 (總數) : 1; 背的軟條 (總數) : 6 - 7; 臀棘: 1; 臀鰭軟條: 4. This species differs from all its congeners except A. verecundus, A. jataiensis, A. reisi, and A. tombador by the absence of an adipose fin; a series of 4 to 6 small median, unpaired platelets forming a low postdorsal ridge covers the area otherwise occupied by the adipose fin. It differs from A. tombador and A. verecundus by the presence of tentacles on the snout of adults (vs. absence or reduction of tentacles), and by a lower number of plates of the dorsal plate series between the end of the postdorsal ridge and the origin of the first plate-like procurrent caudal-fin ray (one or none vs. two or more). It is further distinguished from A. tombador by the predorsal length (45.3-47.1 vs. 42.7-45.1% SL), head depth at supraoccipital (18.7-19.4 vs. 15.6-16.9% SL), cleithral width (32.4-33-6 vs. 27.531.2% SL), body width at dorsal-fin origin (27.8-30.5 vs. 22.826.9% SL), caudal-peduncle length (25.6-27.9 vs. 29.4-32.4% SL), and the number of plates between the anal and caudal fins (9-10 vs. 11-12). It differs from A. reisi and A. jataiensis by a narrower mandibular tooth row (14.8-17.0 vs. 19.4-24.0% HL), fewer teeth (50-59 vs. 62-80 on dentary and 47-55 vs. 61-80 on premaxillary), and by a lower caudal peduncle (8.5-9.4 vs. 9.6-10.7% SL), respectively (Ref. 56914).
Body shape (shape guide): elongated.
這種除了 A. verecundus ， A. jataiensis ， A. reisi 與 A. tombador 藉由缺少一個脂鰭以外有別於它所有的同類; 一系列的 4 到 6個形成一個低的後脊小中央又不成對的小板覆蓋不一樣地被被脂鰭佔領的區域。 它有別於 A. tombador 與 A. verecundus 藉由在成魚 (vs. 缺乏或觸鬚的減少) 的吻部上有觸鬚, 與藉著在後脊的末端與第一個的起源之間的背部碟系列的一個碟的低數字板狀的前流尾鰭鰭條 (一或沒有和二個或更多比較). 它是進一步區分 A. tombador 在上枕骨 (18.7-19.4 vs.15.6-16.9% SL) ，匙骨寬度 (32.4-33-6 vs.27.531.2% SL) 的藉由前背的長度 (45.3-47.1 vs.42.7-45.1% SL) 頭部深度, 在背鰭起點 (27.8-30.5 vs.22.826.9% SL) ，尾柄長度 (25.6-27.9 vs.29.4-32.4% SL) 的身體寬度, 與在臀鰭與尾鰭之間的碟的數字.(9-10 vs.11-12) 它有別於 A. reisi 與 一個比較狹窄顎的齒列 (14.8-17.0 vs.19.4-24.0% HL) ，較少的齒 (50-59 vs.62-80 在齒骨上與 47-55 vs.61-80 上頜骨前的之上) 的 A. jataiensis, 與藉著一個下尾部梗 (8.5-9.4 vs.9.6-10.7% SL), 分別地.(參考文獻 56914)
