E-mail: [email protected] A lmost one year ago, between August 25-31, 2019, we were glad to organize the 18th International Congress of Myriapodology, at the Hungarian Natural History Museum in Budapest. Ninety two scientific participants (plus 13 accompanying persons) arrived from 32 countries, all around the world. Only now, in the present pandemic situation, do we realize, how lucky we were that we could organize such a great congress. The meeting was successful not only in the number of participants: During the four scientific days we had 48 lectures (including four invited plenary presentations) and 55 posters, which covered a wide range of the field of myriapodology, from the zoological subjects of morphology, anatomy, taxonomy, systematics, physiology, biogeography and nature conservation. We also had a joyful day excursion to the nearby Buda Hills, where participants could encounter some representatives of the local soil fauna. In the name of the organizing committee we would like to thank our 16 Hungarian colleagues who helped to make the congress really enjoyable. From the presentations, 11 scientific papers have already been published in a Special Issue of Zookeys (No. 930), and now we are presenting here another 7 papers. We are grateful to the editors of Opuscula Zoologica, Prof. Csaba Csuzdi and Prof. Árpád Berczik for providing the opportunity to publish this second volume of the cross-section of the 18th International Congress of Myriapodology.
