@KlausRiede @FishInTheNews Thanks for your attention to this. The “Genus-species” name formatting issue seems to be a quirk of the web version only. The PDF (version of record) is correct. The genus is established in the text per ICZN, and this journal's guidelines prohibit new names in titles/abstracts.

Delighted to share the discovery and description of the first scale-feeding candiru from west of the Andes Mountains. The new genus and species Arhinoglanis relictus is a miniature, paedomorphic species endemic to the upper Cauca River basin in Colombia.

@shanling600 Hi, do you know where these were collected?

New paper alert: A time-calibrated phylogeny of Neotropical freshwater fishes, the most diverse continental fauna on Earth.

Built from a supermatrix of 51 genomic markers for 3,167 species, the most species-rich phylogeny of this fauna to date.

Mago described 12 new electric fish species in his magnum opus in 1994, bringing the total number of described species to 94. Easy to remember, 94 in 94. He told me then the final total would be more than 300 species. I remember wondering, where would all those species be?

I think it's more accurate to say that fish are criminally understudied and that mammals are overrated 😎
