Dear Sir/Madam,
I am uploading one image (I guessed its a Lestranicus transpectus)for indentification purpose. Species captured from Kaptai national park, Bangladesh in the month of March 2019. Please guide me to give the id. Also please guide how could differentiate between Celastrina huegelii, Celastrina argiolus, Celastrina gigas, Udara dilecta and Celastrina luvendularis. Please guide
Regards,

Yes this is Lestranicus transpectus.
HW postdiscal spot 7 very large & rounded, much darker than the other postdiscal spots below it.
The other postdiscal spots are also rather large & rounded.

Udara dilecta;HW postdiscal spot 7 small & not darker than the other postdiscal spots below it.
The other spots are variously shaped & narrow.

The Celastrina species are very difficult so I may not be absolutely right.
Celastrina lavendularis ;Underside rather dark & all spots are dark with white halos.
Postdiscal spot 7 is dark, & postdiscal spots 2 ,3, 4, 5, in a low arc.

Celastrina gigas.Un. pale & all spots tiny; postdiscal spot 2 or 3 may be missing, so only after the doubled spot 1b, there are only 3 spots, ie spots 2. 4, 5 or spots 3, 4, & 5.

Celastrina huegelii; HW postdiscal spots 2, 3, 4 ,& 5 present. spot 2 being shifted slightly in, spot 3 always tiny . postdiscal spots barely with halos.

Celastrina argiolus; HW spots small, postdiscal spot 7 larger & darker, all postdiscal spots 2, 3, 4, & 5 present, spot 2 more strongly shifted in than in C. huegelii.
