Hi,

my name is Stephan Kleinfelder, I'm born in 1995.

I finished my Bachelor of Science (Biology) 2023 at the Technische Universität Darmstadt with a focus on Ecology and Entomology (Army ant refuse deposits – nursery for myrmecophiles?).
I finished my Master Of Science (Ecology andf Evolution) 2024 at the Goethe-Universität Frankfurt with a focus on Ecology and Entomology (Influence of large- and small-scaled structural forest attributes on ground-dwelling arthropod communities in the Bohemian Forest: https://www.researchgate.net/publication...Bohemian_Forest)

Since 1998 I'm interested in insects, since 2011 I deal with them in a more professional context
2021 I started to collect specimens and specialize in entomolgy, in 2024 my collection has 2800 specimens out of 1500 species.

Since 2022 I'm specializing in Dermapterology, with 31.000 identifications on iNaturalist, 40 german wikipedia articles and a long correspondence with Danilo Matzke, Petr Kočárek, Paolo Fontana, Boris Eliseev, Mario García-París, Fabian Haas, Martin Husemann, Laura Rivero Martinez and others.
I also have a dry collection of Dermaptera with currently 57 species and 189 specimens (I always want to collect more).
2024 I helped Alban Pfeifer with the new red list about german Dermaptera and 2025 I resorted the Dermaptera collection of the SNHM Karlsruhe.

My life goal is to create an updated version of Steinmanns monographs, to create the most accurate taxonomic list of Dermaptera and to classify all species by key by their nymphs. Up to now I have 2042 species in my list of Dermaptera with the newest sources. I also would like to start with a book like "The Dermaptera of the western palearctic realm" with 100% of the information to ever gathered about those species. Could be followed by volumes like "Dermaptera of the eastern palearctic realm" and "Dermaptera of the nearctic realm". But at first I need to do my PhD.

Out of private reasons, in the next years I will work in different ecological companies and won't start my PhD until 2026. I wish that my PhD will be about european Dermaptera, like the borders of the Forficula auricularia-complex in France, Belgium, the Netherlands and Germany and the possible Isolabella graeca-complex in Greece and Turkey. Also DNA barcoding of european Anisolabis maritima would be informative and needed and other topics too.
