This should be correct as Halpe elana. Correction: Halpe zola.

I have check through all the Halpe species present in Indochina.
Only five species have a typical band ie H. zema, zola, zinda , ormenes, & elana.

Halpe ormenes. UnH band ( often white )with both margins regular.( Not found in vietnam)

Halpe zema. Band yellow; Outer margin of HW band in space 2 &3 sharply deep serrated. Band usually fall short of touching the costa.

Halpe zola. Band yellow; outer margin in space 3 retain the sharp point ;in space 2 the outer margin is blunted.
HW band often reaches the costal margin.

# 21 . Although it looks somewhat like the male Halpe zema at Mae Hong Son, have the band in space 2 & 3 blunted, not serrated.

The sharp serrations in space 2 & 3 ,of the band's outer margins in Halpe zema is a consistant feature.
