Separation of Cynitia "Blue Count" types

[DaveChiangMai]

Reviewing my Cynitia species images I am wondering if the various "blue count" types are correctly identified and even how to really differentiate them (primarily uppersides). The confusing species would seem to be:

Cynitia flora Blue Count, both sexes
Cynitia godartii Malay Count, male
Cynitia cocytina Hosfield's Baron, male

I couldn't find any postings on this specificly.
Many thanks

I find these three very confusing especially since cocytina was once a race of iapis, which is now shown to only occur in Sumatra, Borneo and Java and associated islands. So all inidividuals from Peninsular Malaya northwards must now be called cocytina

The females are quite easily distinguished from one another but the males differ in only minor details like forewing shape and the thickness of the blue band

They are difficult to ID from field shots.

C. cocytina. HW blue band about equally wide throughout; FW band inner margin never straight, very irregular.

Funet's page suggest both iapis & cocytina are found in Sumatra & Borneo.

Many thanks for the replies. Appreciate that these are very difficult to separate in the field.
