Tagiades ultra?

[horace2264]

Encountered this flat at MNT. Is this Tagiades ultra?
My only doubt is in the lack of white patches between dark spots at the hindwing tornal area.

I do think that this one is Tagiades ultra

[Silverstreak]

Might be a Tagiades litigiosus litigiosus (Water Snow Flat).... look like species #280.

C&P 4 pg 344

Key for separation of the species of Tagiades:

para 16: Upper hindwing tonal area reaches above vein 4: marginal spots at the end of veins 1b,2 and 3 subequal,ill defined and usually conjoined .

Horace shot match Plate 53 fig 27 except for the white abdomen.

specimens IDed as Tagiades litigiosus and have white abdomen are as follows:


Tagiiades at HK site

Tagiiades litigiosus at Thaibug site

Thanks, Sunny for the investigating work for this other Tagiades species.
Looking at the plate for T. litigiosus at http://www.hkls.org/butt-hesperiidae.html#
it seems that only the female has this feature that the hindwing marginal spots are "fused" together. I just wonder whether the same is true for T. ultra that the two sexes have such a distinction?
