Kohout, Rudolf J.

Biographical Notes
Rudolf J. Kohout was born in Checheslovakia where he studied at the Academy of Fine Arts. After emigrating to Australia, he worked for many years at the CSIRO where he was a specialist on scientific illustrations of ants.

He soon developed into a taxonomic expert on the species rich ant genus Polyrhachis commonly known as spiny ants. Rudy continued working on spiny ants even after his retirement when he became an honorary research fellow of the Queensland Museum in Brisbane. Altogether he worked more than two and a half decades on Polyrhachis. During this period, he published more than 40 publications on these ants. Rudy is well known among ant researcher for his thorough revisions where he altogether described more than 250 Polyrhachis species new to science. His work is crucial for the modern understanding of this important and diverse ant genus of the old world tropics. Beside being a prolific taxonomist, Rudy was also a very keen field scientist with own collecting works in many countries: Australia, Papua New Guinea, Malaysia, Brunei and many more. With the specimens collected in these countries, he built up a large collection of spiny ants, but he also kept his collection growing by exchanging samples with other ant researchers. On the other side, he was always helpful when his colleagues needed some Polyrhachis specimens for their own studies.

Rudy loved being connected with other ant researchers. Those you meet him personally describe him as a great friend and colleague as well as an engaging companion and an endless fund of good stories. With his support to ANeT (International Network for the Study of Asian Ants), he was especially engaged in supporting the next generation of myrmecologists. Therefore, he was awarded 2007 at the 6th ANeT meeting in India with a special award for his extraordinary contribution to myrmecology in Asia. He also supported the start of Asian Myrmecology, the scientific journal of ANeT. For this reason, he published many of his high quality taxonomic publications in the very first issues of this journal which were an important cornerstone for the later success of Asian Myrmecology. He was also honored by Australian colleagues who named a new discovered spiny ant after Rudy: Polyrhachis kohouti Hoffmann 2015.

Rudy passed away after a long illness on 26th May 2016. His family, friends and colleagues still miss him, but they will always keep alive the memory of Rudy.
