簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 7 - 8; 臀棘: 1; 臀鰭軟條: 4. This species is easily distinguished from all congeners, except A. jataiensis, A. parecis, A. reisi, and A. tombador by the absence of an adipose fin which is replaced by a series of 3 to 5 median, unpaired platelets forming a low postdorsal ridge. It also differs from all congeners in lacking an adipose fin, except for A. tombador, by the naked margin of snout broad and the reduced development of snout tentacles in both sexes (usually absent), and by the presence of two or more plates of the dorsal plate series between
the end of the postdorsal ridge and the origin of the first dorsal procurrent caudal-fin (vs. one or none). This species is distinguished from A. tombador by the head depth at supraoccipital (17.9-19.3 vs. 15.6-16.9% SL), cleithral width (31.4-33.1 vs. 27.5-31.2% SL), interorbital width (15.9-16.8 vs. 12.7-15.1% SL), and by the base of the first anal-fin pterygiophore covered by skin (vs. exposed) (Ref. 56914).
除了被形成一個低的後脊的一系列的 3 到 5個中央又不成對的小板取代的藉由缺少一個脂鰭是的 A. jataiensis ， A. parecis ， A. reisi 與 A. tombador 以外,這種是與容易地區分的所有同類。 它也有別於在缺乏一個脂鰭中的所有同類, 除了 A. tombador, 藉由裸露邊緣吻寬的與吻觸鬚的被縮小的發展雄性與雌性都有 (通常不存在), 而且藉由有背部碟系列的二個或更多碟在
後脊的末端與第一背鰭的起源前流的尾鰭.(vs. 一或沒有) 這種被區分 A. tombador 藉由頭部深度在上枕骨 (17.9-19.3 vs.15.6-16.9% SL) ，匙骨寬度 (31.4-33.1 vs.27.5-31.2% SL) ，眼間骨寬度 (15.9-16.8 vs.12.7-15.1% SL), 與第一個臀鰭支鰭骨的基底被皮膚 (vs. 裸露的) 蓋著了藉由.(參考文獻 56914)

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00580 - 0.02997), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
