If the locality in the data label is incorrect I recommend stating the original data followed by 'loc. err. = XXX'

If the stated data is retained, then it has not been 'lost' if it is subsequently found to be correct.

Middle picture S cambodia. All specimens from Kanchanaburi Thailand Perhaps the correct data is Chantaburi (similar sounding name, especially the shortened spoken Thai form "Kanburi" versus "Chanburi"). S. cambodia does not occur in Kanchanaburi, which is in WEST Thailand, it is...

Transient to a small plateau? Certainly not transient to the island, right? Yes, indeed. The taxon is isolated on the island, but the place that the holotype was caught (the type locality) is an area where males visit/pass through, rather than staying there all the time. Why didn't this ssp undergo...

I saw Stichophthalma flying in Laos in the daytime, I don't think they are only crepuscular.

Looking more closely at the second male, it looks more like P. chikae based on the spatulate tails. You should check the forewing underside, in hermeli the apical and subapical areas are strongly suffused with grey scales, whereas in chikae these scales are more diffuse, except near the tornal angle...

It is difficult to judge size from the photos, but the first generation (that went through diapause) of many subgenus Achillides species are often smaller and have brighter colouration. Do your specimens have dates on them?

I've never seen one quite like that anywhere this
side of the pond !

I think it may be a first 'spring' generation specimen. Probably it is distinctly smaller too.

Adam.

Yes, and there are some male scales near the apex of the left forewing too.

It would be interesting to see a photo of the underside, often mosaic gynandromorphs also have strange patterns on the underside, which may not correspond to the mosaic on the upperside.

According to Inayoshi's website at http://yutaka.it-n.jp/ama/50280001.html S. mathilda does not occur in Thailand, and he also states: Monastyrskii,2008 treated this species as distinct species, however some authors regard it as a subspecies of louisa . The relationship and taxonomic status of louis...

Dave, could that VERY chocolate-brown looking specimen be a quite (melanic) aberration of something ? Extraordinary find .... 🎉👏 That is a very dark specimen of a rather variable taxon. Here's the page on Inayoshi's website: http://yutaka.it-n.jp/ama/50290020.html As you can see none of the figured...

I corrected the spelling of the species name.

Nice pair of this endemic species.

I thought that the Troilus group consisted only of P. troilus and P. palamedes You will see that P. esperanza is sister to these three species, and as a result of his separate analysis Nick Grishin described the new subgenus Esperourus 2020 in a paper "Genomics-guided refinement of butterfly t...

I wasn't aware of that - I thought that the Troilus group consisted only of P. troilus and P. palamedes, and that both the Troilus and Glaucus groups were classified under the subgenus Pterourus? I prefer to treat Pterourus as a subgenus of Papilio rather than a separate genus too. Wu et al. (2015)...

Is there something new, or did I misunderstand Vernygora et al "Gauging ages of tiger swallowtail butterflies using alternate SNP analyses " (2022) Sorry if you are confused ... I said Pterourus GROUP, not GENUS. The type species of Pterourus is Papilio troilus , so strictly there are onl...

I think I read once that the Stichophthalma were going to be revised. Yes, it is a Japanese researcher's project, but will take a long time. In this genus the genitalia are all the same, so that is not a good guide to distinguish the species. I expect that it will be necessary to do NGS ('Next Gene...

Chuck wrote: ↑Sun Jan 22, 2023 5:31 pm What a spectacular species!

Yes, it is the 'King' of the remaining genus Euthalia in Thailand, as opposed to Lexias which used to be included in Euthalia.

Adam.

While we're on the topic of tiger swallowtails, it's worth mentioning another spectacular member of the glaucus species group, P. pilumnus, which is only a quite rare stray into the US This is a misconception based on the striped wing pattern. Papilio pilumnus belongs to the Pterourus group, with P...

It is univoltine in March-April here Looking at the link to the webpage I posted above for this species from Inayoshi, Butterflies in Indochina it seems I was mistaken - there is a second generation in October. It is a pity that there is no useful locality data on your specimen other than 'north', ...
