New Species Named After UniLodz Researcher!

The scientific community has once again honoured Prof. Philippe J.R. Kok from the Faculty of Biology and Environmental Protection at the University of Lodz. A recent publication in the Journal of Vertebrate Biology describes a new species of caecilian from Guyana – Rhinatrema koki, named in his honour.

The paper authors, Mark Wilkinson and Gabriela Bittencourt-Silva, have demonstrated that the specimen, housed in the Smithsonian Institution's collection since 1998, belongs to an entirely new species. Rhinatrema koki is distinguished by, among other things, a light spot on its head, a unique arrangement of teeth and a different skull structure. This is an extremely rare animal, previously known from only a single specimen.

This is the third species named in Prof. Kok's honour, following a frog (Pristimantis koki) and a snail (Plekocheilus philippei). That’s how the international scientific community recognises his contributions to biodiversity research in Guyana and South America.

Prof. Kok is a renowned herpetologist specialising in the study of neotropical amphibians and reptiles. For years, he has conducted extensive fieldwork in Guyana, discovering and describing new species. His research contributes to the understanding and conservation of one of the world's most unique ecosystems.

The discovery of Rhinatrema coki not only expands our knowledge of amphibian diversity, but is also a source of pride for the entire UniLodz community.
