Girardinus metallicus

• ... that Girardinus (pictured), freshwater fish found only on the islands of Cuba, are thought to have crossed an ancient land bridge, though scientists disagree where it was?

• Source: "The first and most developed model is that proposed by Rivas (1958), in which the ancestor of today’s Girardinus colonized Cuba from the eastern Yucatan during the Upper Miocene–Pliocene across an intercontinental Yucatan-Cuba landbridge ... "An alternative model has been developed to explain the presence of Poeciliidae representatives in the Antilles, including the tribe Girardinini across GAARlandia (Greater Antilles + Aves Ridge). This model of geological evolution of the Caribbean basin suggests that the Greater Antilles did not permanently emerge until the Eocene-Oligocene boundary (30–35 mya), when they were connected to northern South America by the Aves Ridge."

• • ALT1: ... that Cuba's Girardinus fish (pictured) may have evolved into different species because the island's rivers are interrupted by waterfalls and sinkholes? Source: "The country's karst topography determines that some rivers are fragmented by waterfalls or disappear for kilometers underground and may also be the cause of local speciation events in freshwater fishes such as Girardinus with a limited capacity for dispersal."

Overall: Everything looks good except for one thing - this statement in para 4 "Carlhubbsia from Central America has also been proposed as a sister genus" is supported by a citation to Rivas (1958), but working my way through that article, I can't find unambiguous support for this. While Allophallus (as the genus was known at the time) is mentioned in Table 1 (p. 299) I don't Rivas saying anything that supports this particular statement. Granted, it's a long, dense article to parse, so I may have missed something, but I think switching the citation to This source is a publication such as a book, journal, or other printed material. Doadrio et al. would be a better idea, since they clearly say that Carlhubbsia is considered a sister taxon (which rejecting it). Actually I have a second question too - the WoRMS link is giving me "Oops! This taxon is out of scope!". Maybe switch it to Fishbase? Guettarda (talk) 18:52, 1 January 2026 (UTC)

Thanks, Guettarda. I do not mind removing the reference to Rivas. Yes, the source for ALT1 is Doadrio et al. (2009). Funny that you mention the WoRMS link–I included it instead of FishBase because I can open WoRMS but not FishBase! Surtsicna (talk) 20:39, 1 January 2026 (UTC)

Great Surtsicna. Nice work! Guettarda (talk) 21:39, 1 January 2026 (UTC)

• @Surtsicna: + @Guettarda: reviewed for promotion. Everything looks good except I'd like to double check the image license before it could be moved to a prep slot 1. I might be missing something but it seems like the commons file is missing source information, and the source URL is dead for me. Zzz plant (talk) 16:21, 26 January 2026 (UTC)

It seems that it's not missing source information; the source information is misplaced. The URL is indeed dead. The image was apparently uploaded in 2025, so that's not surprising. If you are in the mood for a fish photo, Zzz plant, it might be easiest to replace the image. File:Giraldinus falcatus.jpg and File:Girardinus metallicus (metal girardinus) (cropped).jpg might be good candidates. Surtsicna (talk) 16:38, 26 January 2026 (UTC)

thanks @Surtsicna: would you mind adding File:Girardinus metallicus (metal girardinus) (cropped).jpg to the nomination page? Zzz plant (talk) 16:46, 26 January 2026 (UTC)

I have added it both here and in the article, Zzz plant. Surtsicna (talk) 17:21, 26 January 2026 (UTC)

@Surtsicna ALT1 doesn't have a source attached to it. Am I correct in assuming it's Doadrio et al. (2009)? Guettarda (talk) 17:41, 1 January 2026 (UTC)
