Defining features for distinguishing closely related butterfly species

and the Japanese don't have anything intelligible? I just don't understand their scribbles

Fthere is a female here

Here it is somewhat better, you need a female, I can take a picture with GME3

Thanks! We'll figure it out.

Is it possible to distinguish the pigeons of argus, idas and argyrognomon by their external signs???

if I'm not mistaken, the topic of "golubyanka" was the definition of this complex. in fact, with a large amount of material, they are quite easy to distinguish, at least males unfortunately, I transferred this information to another computer when I had Windows showered, and there is no access to the dumb now

Definition of pigeons of the genus Plebejus
Argus
-Male is well cast - from the top on the hind legs. an additional cell is painted black near the costal edge. Argyre and idas have it blue.
- The fringe of the male is white, very broad, especially on the hind wings.
- female argus-on the underside is characterized by a strong reduction of the red spot near the apex of the rear wing.
- The general background of the underside of the male is bluish

Idas
-The male's fringe is grayish, rather narrow.
"On the underside of my ass." there is a full row of developed shiny holes.
"On the underside of my ass." kr sharp white brackets.
- on the underside of the rump, black brackets are often moved away from the edge of the wing.
- On the underside of the ass - a full row of red spots (in argus - incomplete)
- The general background of the male's underparts is light brownish

Argyrogomon
-The fringe is narrow
-Shiny spots are very poorly developed.
- Black brackets are shifted to the edge of the wing
- White brackets are poorly developed, rounded.
- Black dots on the underside of the KR small (Idas often large)
- The butterfly is smaller than Idas, the wings are more rounded
- The general background of the male's underparts is gray
