- Key to species in the Aphanius dispar group It should be noted that more than one species seems to be involved in A. dispar from the Red Sea basin and only limited material was available from the different molecular groups. The identification key is based on A. dispar from the northern Red and Mediterranean Sea basins. Other populations from the Red Sea may not be identified using this key. 1a Caudal fin emarginated; body without scales......................................................... A. furcatus 1b Caudal fin truncate; body covered by scales................................................................. 2 2a Lower jaw sharply upturned, oriented about 90° to body axis.......................................... A. stiassnyae 2b Lower jaw gently upturned, oriented about 45° to body axis.................................................... 3 3a Female with a midlateral row of roundish, black spots, often with additional black spots on flank; male with a wide, black dorsal-fin margin; anal fin yellow, with or without a narrow black margin and 0–2 short black bars on middle of fin...
