New to science and the aquarist: Kapuasia falaris

Kapuasia falaris

Never heard of the genus Kapuasia? That’s what happened to me when a loach labelled as Kapuasia maculiceps was shown as newly imported on the website of Dutch wholesaler Ruinemans at the beginning of November 2024.

The genus Kapuasia was established in early 2024 by Kottelat and Tan for the taxon maculiceps, which was previously in Schistura and described as Nemacheilus. It is named after the Kapuas River basin in Borneo.

The Zebra Otocinclus, a species with two faces

The Zebra Otocinclus is probably the most spectacular and most attractive Otocinclus species for the aquarium hobby. It has been known for some time that there are two forms of the species described in 2004 as O. cocama: one from the lower Río Ucayali and another one from the Río Tigre. Both rivers are tributaries to the Río Marañón, which ultimately flows into the Amazon. While the Ucayali form, on which the description is based, has been exported for the aquarium trade since around the turn of the millennium, it is mainly the Tigre form that has been on the market in recent years, at least in Germany. Both populations can be clearly distinguished by their stripe pattern. The question of whether the populations can also be distinguished morphologically and genetically, and thus also whether they are merely variants of one species or two distinct species, was investigated by Eduardo MEJIA and Roberto E. REIS and recently published. Continue reading
