03FF87A5FFF6833EE4D0D6AEFC5FD8FC.taxon	etymology	Etymology. The species is named in honor of Dr. Martin Nemček (Bojnice, Slovakia). Acknowledgments We are thankful to † Vasiliy Kravchenko (Tel Aviv University, Israel) for preliminary work in the Ekongo camp in March and April of 2017: setting up most traps, training local workers, and taking care of material under harsh conditions. We express our gratitude to the LuiKotale Bonobo Project leaders Barbara Fruth and Gottfried Hohmann for their help with the general curating of the insect collection from the project in Ekongo. A heartfelt thank you to LuiKotale and Ekongo camp managers Roman Keller and Alexis Louat who helped to organize, manage and maintain the daily work efforts in the camp. We appreciate the irreplaceable help of the Bekombo village people with collecting, sorting, packing, and transporting insects from Ekongo as well as with the daily routine in the camp. A portion of the presented work was done by † Vadim Zolotuhin and Alexey Prozorov with the financial support of the Thomas-Witt-Stiftung.	en	Revay, Edita E., Prozorova, Tatiana A., Cipolla, Alexandre, Volkova, Julia S., Saldaitis, Aidas, Yakovlev, Roman V., Sulak, Harald, Müller, Günter C., Prozorov, Alexey M.
