Editor's Picks

A new species of bagrid catfish has been described from Borneo.

Heok Hee Ng of the Museum of Zoology at the University of Michigan and Darrell Siebert of the Fish Division at London's Natural History Museum described the new species of catfish as Pseudomystus stenogrammus in the latest issue of the systematics journal Zootaxa.

The holotype was collected in Kalimantan Tengah in Borneo by Darrel Siebert, H. Tjakrawidja and the Natural History Museum's Curator of Fishes, Ollie Crimmen, during an expedition in 1992. Most of the specimens captured measured around 9cm/3".

The new catfish closely resembles Pseudomystus mahakamensis but has a thinner midlateral stripe, a shorter adipose base and a wider head.

The Pseudomystus genus contains around 14 species most of which are found in the rivers and swamps of Asia.
