簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 10 - 13; 臀鰭軟條: 10 - 12. This species is clearly distinguished at the genetic level from its congeners in having 82 molecular apomorphies-19 transversions, 2 transversions/transitions (depending on comparison), and 61 transitions - that show fixed character state differences to homologous characters analyzed in sophiae, persicus and vladykovi from Iran. Thirty-seven of these character states are also apomorphies when compared to anatoliae, danfordii, villwocki, asquamatus and fasciatus from Turkey (see www.cyprinodontiformes.org).
Males can be distinguished from all other Iranian species by having distinct black edge on the dorsal, anal, and pelvic fins; the dorsal fin is covered with a high density of black blotches (also observed in males of Aphanius anatoliae from Turkey).
Females can be distinguished from those of sophiae and vladykovi by having flank-bars rather than spots; from persicus by less well-defined bars terminating at a mid-flank stripe and a relatively light gray stripe at the caudal-fin base rather than a black spot or blotch. However, flank-bars are also characteristic of females of dispar and fasciatus. Aphanius isfahanensis can be distinguished unambiguously only from vladykovi by a lower lateral-line scale count, but not with any morphometric or meristic character from sophiae or persicus (Ref. 57741).
Body shape (shape guide): fusiform / normal.
這種清楚地在來自它的同類的遺傳的水平被區別有 82 分子的 apomorphies-19 transversions ， 2 transversions/轉變 (依據比較而定), 與 61個轉變 - 那一個顯示固定的特徵說對在來自伊朗的 sophiae ， persicus 與 vladykovi 被分析的相應的特徵不同。 當相較於來自土耳其的 anatoliae ， danfordii ， villwocki ， asquamatus 與 fasciatus了，這些特徵描述中的三十七也是 apomorphies 。 (見 www.cyprinodontiformes.org)
雄性能被與全部其他的伊朗種區分在背鰭、臀鰭與腹鰭上藉著具有明顯的黑邊; 背鰭被覆蓋著黑色斑塊的高密度。 (也在來自土耳其的 Aphanius anatoliae 的雄性觀察)
雌性能被與 sophiae 的區分，而且 vladykovi 藉著具有側面-橫帶而不是斑點; 從比較少量的 persicus 很清晰橫帶在尾鰭基底結束在一條側面中央斑紋與一條相當淡灰色的斑紋而不是一個黑色的斑點或斑塊。 然而, 側面-橫帶 dispar 與 fasciatus 的雌性也是獨特的. Aphanius isfahanensis 能清楚地被區別只從低側線鱗片計數的 vladykovi, 但是不和來自 sophiae 或 persicus 的任何的型態特徵或體節的特徵.(參考文獻 57741)
