I believe I observed the first Ichneumon laetus wasp on iNat back in November, but I’m not 100% on the ID.
I found list with some old an dirty statistics. Taxa <> species.
here’s some quick an dirty stats (e.g. 93,728 taxa with 1 obs)
1 obs: 93728
2 obs: 45372
3 obs: 29082
4 obs: 20902
5 obs: 16274
6 obs: 10756
7 obs: 9107
8 obs: 8113
9 obs: 6940,
10 obs: 6152

Wondering if it’s possible to filter these for my own observations? Here is one of mine that’s the only observation of a tree fern (https://www.inaturalist.org/observations/35625058). I know I’ve been the first to add various other species to iNaturalist, but don’t know of a way to find them again now…
yes. https://jumear.github.io/stirfry/iNatAPIv1_observations_species_counts.html?order=asc&user_id=deboas.
look for taxa where both counts =1.
right now:
- Afrixalus weidholzi (Weidholz’s Banana Frog)
- Phrynobatrachus villiersi
- Schumanniophyton problematicum
- Solanum leucodendron
- genus Megalorrhipida
- Darditilla araxa
- Pedinorrhina recurva
- Ehretia trachyphylla
- Ceriomura damborskyae
- Eusapia amazonica
- Soyauxia velutina
- Aporrhiza urophylla
- Trentepohlia arborum
- Donella pruniformis
- Leptopecten bavayi
- Cladonia sphacelata
- … and many more!!!
interestingly, across the platform, we’re now down to 110 x 500 + 70 = 55070 leaf taxa with just one observation.

is it possible to download the results as a CSV file, so that I can filter for the value ‘1’ of Total Obs Count in Excel?

just copy and paste a few pages?
somebody could write something that would automate the whole discovery process for taxa with only one observation by user, but that page already gets you pretty close, i think.
Directly copy+paste of the first page makes Excel crash, and I’d have to check 2,500 to 3,000 entries.
A more elegant solution I would highly appreciate, so hopefully somebody will tackle this task.

Brilliant, thank you!

Perfect, that works! And already found some unique species I had missed so far!

The inquiry address was quite useful!
For some reason mine are all Lepidoptera and most of them very small… 
These should be relatively certain:
Elophos andereggaria
Idaea vilaflorensis
Cydia archaeochrysa
Pontoturania defessana
Agonopterix vendettella
Merrifieldia particiliata
Zelleria wolffi
Caloptilia aurantiaca
The ID for these is by J. Tabell, but he was not quite certain of first. For the next there is a second possibility, but that is most likely a synonym for this. 
Coleophora orotavensis
Coleophora pseudopoecilella
The last four are more than a little uncertain - especially the last two. Those two species are rather difficult to tell apart.
Altenia perspersella
Phtheochroa frigidana
Xenochlorodes magna
Xenochlorodes nubigena
Chysobothris parvipunctata, a single observation by me when I didn’t even know what species it was
The spix’s macaw, someone observed it in 1992 before extinction. Similarly, the Hawaiian crow
There is only 1 wild observation of a rainbow shark

And both have long threads of agreeing identifications. I suppose that is how iNatters pay their respects.

I realized I currently have the only observation of the tiger beetle Abroscelis psammodroma!

I got a couple galls on this list, thanks to @Megachile this week:
https://www.inaturalist.org/observations/106191316
https://www.inaturalist.org/observations/99284614
Winter is great gall-hunting season
A few of mine (I’m sure I am missing some):
Bothrideres geminatus
Chlaenius canariensis
Onthophagus nitidulus
An unidentified Cyphostethe sp. (sorry about the awful photo here - I plan to get a better one)
Augyles flavidus
Cymindis hierichontica
Glareadessus stocki
Anthaxia pinda
Leiopsammodius indicus
A tentatively identified Rhyssemus brevitarsis
Hyphydrus pictus
Hydroglyphus angularis
At least as many more are at the genus level because the species is not yet added and my flag to add it has sat for months without notice. At least twice as many more I am the only observer of but have submitted multiple observations of.

None of these are mine but I found them interesting so I thought I would share anyway, hope that’s okay! Disphragis tricolor, D. carantis and D. mullinsi all only have one observation.
