Looking at a few older Nacaduba sp. photos, these two are slightly odd. Appreciate confirmation of ID please.
Thank you.

Image 1. From Kaeng Krachan NP, northern peninsula Thailand.
Looks like N. hermus I think.

Image 2. From Phu Suea NP, nw Thailand.
Looks like N. sayana based on dislocated postdiscal band.

2nd one is Jamides bochus bochus from the configuration of the striae. Nacaduba and Jamides have a subtle difference in the appearance of their striae but it's hard to describe. Also, this (http://www.butterflycircle.com/showthread.php?15671-Nacaduba-sp&highlight=bochus)

1st one is difficult because i'm not familiar with how the northern ssp. of Nacaduba spp. look like

1. is N. hermus

N. hermus is one of the few 4line blue with metallic scales in the HW black spot.
Normally HW submarginal & postdiscal spots in space 4 & 5 touch.

Jamides have the white striae form a sharp spike near the inner margin.
