Aphanius anatoliae anatoliae (Leidenfrost, 1912)

( Figures 3 , 4 )

All otoliths of Aphanius anatoliae anatoliae possess a flat or faintly convex inner face and a slightly or moderately convex outer face with a thickening in the posterior portion and rarely also in the middle part.

Localities—Lake Salda: near Yeşilova (22 specimens) ( Figure 3a–f ); between Salda and Doğanbaba (seven specimens) ( Figure 3g –j )

Description. (1) Outline: trapezoid; (2) excisura: U- or V-shaped, deeply incised, but smooth in smaller otoliths; (3) rostrum: as long as or longer than the antirostrum; (4) antirostrum: rounded, thickened, and pronounced in most specimens; (5) dorsal rim: slightly curved and smooth or crenulate; (6) posterior rim: sloping; it may show an incision at the sulcus level; (7) ventral rim: straight or sometimes slightly curving; (8) crista superior: bulging; (9) crista inferior: weakly developed; the area beneath the crista is sometimes provided with little knobs.

Remark. Two pairs of otoliths differed distinctly in their left and right members concerning general otolith shape.

Locality—spring at Düğer near Burdur (five specimens) ( Figure 3k–m )

Description. (1) Outline: trapezoid or triangular (one specimen); (2) excisura: U- or Vshaped, deeply incised; (3) rostrum: slightly longer than the antirostrum, except in one specimen; (4) antirostrum: prominent; (5) dorsal rim: straight to curving; (6) posterior rim: sloping; (7) ventral rim: straight; (8) crista superior: of bulging shape, especially in its rear part; (9) crista inferior: weakly developed; the area beneath the crista inferior displays several knobs of various sizes.

Locality—Işıklı dam near Beydilli (eight specimens) ( Figure 3v–w )

Description. (1) Outline: rounded trapezoid or rounded triangular; (2) excisura: V-shaped, more or less deeply incised; (3) rostrum: slightly longer than the antirostrum; (4) dorsal rim: slightly curving, smooth; (5) posterior rim: sloping; (6) ventral rim: convex, smooth; (7) crista superior: bulging; the area above the crista is more or less deepened (sulcated).

Remark. Mainly small specimens about 17–25 mm were available (except one male with a TL of 32 mm). As a result, otolith morphology may still display juvenile (subadult) characters.

Locality—Lake Avlan near Elmalı (18 specimens) ( Figure 3n–u )

Description. (1) Outline: broad-triangular; (rarely) slightly elongate-triangular ( Figure 3u ) or trapezoid; (2) excisura: wide or narrow, then deeply incised; (3) rostrum: longer to distinctly longer than antirostrum; (4) antirostrum: rounded or slightly pointed, tip usually medially bent; (5) dorsal rim: convex and smooth or crenulate; (6) posterior rim: sloping with convex tendency; (7) ventral rim: slightly curving; (8) crista superior: of bulging shape in its anterior part but it flattens in the rear portion; the area above the crista may be faintly deepened; (9) crista inferior: straight and formed like a thin ridge with the area beneath knobbed.

Locality—floodplain at Lake Eğirdir near Barla (three specimens) ( Figure 4c, d )

Description. (1) Outline: rounded trapezoid (two specimens), elongate-triangular (one specimen); (2) excisura: distinct, narrow or wide; (3) rostrum: longer or distinctly longer than the antirostrum; (4) antirostrum: prominent; (5) dorsal rim: curving, mostly smooth; (6) posterior rim: sloping and crenulate; it sometimes displays a supplementary edge; (7) ventral rim: straight, smooth; (8) crista superior: bulging at its full length or only in the anterior portion and then flattened in the posterior part; the area above is faintly deepened; (9) crista inferior: hardly developed; the area beneath shows little knobs.

Locality—Lake Eğirdir at Eğirdir (five specimens) ( Figure 4e–g )

Description.

Locality—Kovada Canal (three specimens) ( Figure 4a, b )

Description. (1) Outline: variable, elongate-trapezoid, slightly rounded trapezoid or trapezoid to almost triangular; (2) excisura: distinctly incised, V- or U-shaped; (3) rostrum: slightly or distinctly longer than the antirostrum; (4) antirostrum: thin, pointed;

(5) dorsal rim and (6) ventral rim: both straight or faintly convex; (7) posterior rim: sloping; (8) crista superior: bulging; (9) crista inferior: formed as a thin line.
