简单描述
检索表 | 型态特徵 | 形态测量图
脊椎骨: 27 - 28. Easily distinguished from all congeners by having a unique color pattern of male, consisting of dark gray bars on flank, the three anteriormost bars distinctively darker and narrower than posterior ones. Differs from A. carvalhoi by having more anal-fin rays in male (23-26 vs. 21-22), longer anal-fin base length (38.1-40.9% SL vs. 31.4-35.1% SL) and more caudal-fin rays (28-29 vs. 25-26). Urogenital papilla of male not attached to anal fin, pelvic fins not united medially, 22-24 dorsal-fin rays in male and 16-18 in female, 18-19 anal-fin rays in female and 28-30 scales in the longitudinal series (Ref. 54764).
藉由有一个容易地与所有同类区分了在侧面上被包含深灰色横带的雄鱼的独特彩色斑纹，这三个最前面的横带特殊比较深色而窄于在后部的一些。 有别于 A. carvalhoi 在雄鱼 (23-26 vs.21-22) ，较长的臀鳍基底长度 (38.1-40.9% SL 和 31.4-35.1% SL 比较) 与更多的尾鳍鳍条中借着具有更多的臀鳍棘条.(28-29 vs.25-26) 依附于不的臀鳍的雄鱼的泌尿生殖器乳突, 腹鳍不中间地联合了, 在雄鱼中的 22-24个背鳍鳍条与 16-18 母鱼, 18-19個臀鰭棘條母魚與在縱向的系列中的 28-30個鱗片.(參考文獻 54764)
The type specimens were collected in a temporary lagoon with shallow water (maximum depth about 1.5 m) and vegetation composed mainly of grasses, Nymphaea sp., Lutwigia sp., and a large volume of filamentous algae (Ref. 54764).
模式标本在一个暂时的舄湖被浅水区 (最大的深度大约 1.5 公尺) 与植物收集主要地草， Nymphaea sp. ， Lutwigia sp., 与菌丝藻的大体积组成。 (参考文献 54764)
