Non-Latin letters in scientific names and authorships

[aoern]

There are 42 taxa that contain Cyrillic letters in scientific names or authorship strings and 4 taxa containing Greek letters (Feb 2022 edition).

These letters may look like corresponding Latin letters, for example Latin a and Cyrillic а. In any case, they are annoying when searching or comparing strings for equality.

These errors might be caught already in backend side?

The complete list of these errors is found below. The first line gives the ID and scientific name, the second one the erroneous string and the third one the error letter, its position in the string and the unicode code number and its explanation.

Thank you, @aoern!

I'll add providers to these names, and will notify them about reported issues. Pointed letters should be fixed in the source.

[mdoering]

We do flag "homoglyph" issues in the sources, but they can appear anywhere not just in the name: https://www.checklistbank.org/dataset/1107/verbatim?issue=homoglyph%20characters

When you hit the "homoglyph" pill the UI will show where the specific characters is. In the cases above it seems to be some odd kind of dash. To improve the usefullness I suppose we should flag homoglyphs in names with a special issue? And we need to add a routine to validate an entire project like COL to spot those issues also in COL not just in the sources.

I am not sure if Cucumaria croceoϊda should be considered an error. It is like that in the source, it is considered a synonym and it probably is also the original spelling. So why should that be changed?

I agree for searching it would be good to ascii fold that character into an i. Is that not working already?

[mdoering]

@thomasstjerne @yroskov I think noone will know you can press the homoglyph pill - should we maybe do the highlighting automatically on verbatim pages? Any other ideas?

[mdoering]

One example I remember is the plant genus Isoёtes originally spelled like this by Linneaus: https://www.biodiversitylibrary.org/page/359121#page/542/mode/1up

[mdoering]

Many of these homoglyphs likely come from bad OCRs

[yroskov]

...Isoёtes originally spelled like this by Linneaus

Botanical Code (article 60.7) requires to replace diacritic letters in scientific names with Latin transcription (https://www.iapt-taxon.org/nomen/pages/main/art_60.html). ICZN, article 27 prohibits use of diacritics, apostrophes and ligatures in scientific names (https://www.iczn.org/the-code/the-code-online/).

Unfortunately, rules do not require Latin transcription of authorstrings.

In most GSDs and in the CoL, the originally spelled names (with diacritics, ligatures, figures, etc.) are allowed among Synonyms.

But, it is a different subject. Ari pointed to Greek & Cyrillic characters which should not be present in sci. names.

[mdoering]

I did not want to distract from the majority of russian/greek homoglyphs. But one of the first examples was this:

WoRMS Holothuroidea: 329GZ Cucumaria croceoϊda scientificName: Cucumaria croceoϊda ϊ 17 970 (Greek Small Letter Iota With Dialytika)

I did not see that this is actually a greek ι with a diaeresis, not and i. Because if you read the entire §60.7 from ICN it states that exactly the diaeresis is optional and thus can be used:

The diaeresis, indicating that a vowel is to be pronounced separately from the preceding vowel (as in Cephaëlis, Isoëtes), is a phonetic device that is not considered to alter the spelling; as such, its use is optional.

We need to allow for the original spellings in the synonymy. But obviously not with bad homoglyphs!

[mdoering]

We catch some of those with the unusual name characters issue.

• Cucumaria croceoϊda Vaney, 1908
• Allopatides dendroïdes Koehler & Vaney, 1905
• Parathyonacta bonifaznuñoi Caso, 1984
• Peniagone théeli Ekman, 1925
• Synapta pourtalésii Selenka, 1867

[yroskov]

But one of the first examples...

Yes. Our task is just to alert GSD authors about suspicious cases, they will make their decision whether it's a mistake or not.

[yroskov]

We catch...

Of course

[bart-v]

All WoRMS entries reported here are fixed. In the case where the original spelling was not according to ICZN rules, and requires a mandatory change, we still document this, and prefer to keep it as a synonym. Authority names obvious do not need to follow this "latin rule".

[yroskov]

Thank you Bart!
