"No spot" one-spot Grass Yellow!

[MrGee]

We seem to have a "no spot" One-spot Grass Yellow here. Les has identified these as Eurema andersoni sadanobui, which should have a single forewing cell spot. However, all four specimens shown appear to have no cell spot. I am not disputing Les's ID, just posting because it might be of interest to some. Incidentally, we also have the normal "one spot" One-spot Grass Yellow here.

Oh Yes carry on, please dispute!!

As I told you, I am having total trouble with this.

I can not understand a no spot, other than D. brigitta, from Cambodia, which this so obviously is not!

Have you got a new species here?
The male is pale greenish yellow & have a very broad black border on the hindwing.
The excavation of the black border is deeper in space 2 than in the upper space 3 so that the margin is slanted towards the tornus. (not the border margin in space 1a ending on the dorsum.)
In E. andersoni the inner margin of the black border in space 2 & 3 is upright.

PS. It is the other way round. The smaller paler one is the female, but the lack of cell-spot and the inclination of the black border at space 2 & 3 say this is not E. andersonii.

@Seow: I really hope so!

However, the way you have described it seems almost the same as the description of Eurema lacteola in the BC guide to Eurema identification. Except, of course, that also has one cell spot. I cannot find anything reliable on Eurema lacteola. The wikipedia page shows a butterfly with three cell spots, which, I presume must be Eurema blanda. Yutaka's site does not list Eurema lacteola.

I considered E. lacteola, but it is only known from the Peninsular,( as far as I am aware). As you say, Yutaka does not even list the species as being from Indo-China.

There is, however, one further species to consider, Eurema novapallida. However, the male appears too bright, but it is found in your approximate area.

[MrGee]

Based on the shots on Yutaka's site, I don't think it can be Eurema novapallida because that has no hindwing black border and the forewing black border seems too narrow.
