1. https://www.inaturalist.org/observations/268658916
Too blurry & worn.
HW spot 6 looks to be set well inside of spot 7 so likely to be A. unicolor.
The way to find postdiscal spot 6 is to find the cellend bar first.
this si the streak with a bump near the middle.
To the right the rounded spot is spot 6.



2.https://www.inaturalist.org/observations/268678294
Chersonesia intermedia.

Two spp. have the fW postdiscal band inner margin sinuous.

C. rahria. Fw apex with a curved cross-line; one subapical spot.

C. intermedia; FW apex without a cross line; two subapical spots.

3. https://www.inaturalist.org/observations/269099543
Too difficult. Alea subgroup.



4.https://www.inaturalist.org/observations/269397371
hW with tooth;markings as for amphimuta group.
Well-formed V spot suggest A. amphimuta, although the postdiscal band is partially dislocated.



5. https://www.inaturalist.org/observations/269397367
too blur.
FW postdiscal spot 4 appears to be shifted out suggesting alitaeus group.



6.https://www.inaturalist.org/observations/269397339
Likely to be J. celeno.
There is nothing to suggest eitherwise.



7.https://www.inaturalist.org/observations/269397317
Astictopterus jama.
The slender built, narrow wings & uniform colour suggest this.

8.https://www.inaturalist.org/observations/267525708
Allotinus unicolor.
HW spot 6 is set well inside of spot 5 & 7.



9. https://www.inaturalist.org/observations/268553528
Female Isma bononia.
The arrangement of the spots, also a single cellspot and a diffuse spot in space 1b will only match this.
spot size varies & cellspot can be absent.
