簡短描述
檢索表 | 型態特徵 | 形態測量圖
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).
藉由有一個容易地與所有同類區分了在側面上被包含深灰色橫帶的雄魚的獨特彩色斑紋,這三個最前面的橫帶特殊比較深色而窄於在後部的一些。 有別於 A. carvalhoi 在雄魚 (23-26 vs.21-22) ,較長的臀鰭基底長度 (38.1-40.9% SL 和 31.4-35.1% SL 比較) 與更多的尾鰭鰭條中藉著具有更多的臀鰭棘條.(28-29 vs.25-26) 依附於不的臀鰭的雄魚的泌尿生殖器乳突, 腹鰭不中間地聯合了, 在雄魚中的 22-24個背鰭鰭條與 16-18 母魚,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).
模式標本在一個暫時的潟湖被淺水區 (最大的深度大約 1.5 公尺) 與植物收集主要地草, Nymphaea sp. , Lutwigia sp., 與菌絲藻的大體積組成。 (參考文獻 54764)
