Soleglad, ‘[email protected]’ Euscorpius is the first research publication completely devoted to scorpions (Arachnida: Scorpiones). Euscorpius takes advantage of the rapidly evolving medium of quick online publication, at the same time maintaining high research standards for the burgeoning field of scorpion science (scorpiology). Euscorpius is an expedient and viable medium for the publication of serious papers in scorpiology, including (but not limited to): systematics, evolution, ecology, biogeography, and general biology of scorpions. Review papers, descriptions of new taxa, faunistic surveys, lists of museum collections, and book reviews are welcome. Derivatio Nominis The name Euscorpius Thorell, 1876 refers to the most common genus of scorpions in the Mediterranean region and southern Europe (family Euscorpiidae). Euscorpius is located on Website ‘http://www.science.marshall.edu/fet/euscorpius/’ at Marshall University, Huntington, WV 25755-2510, USA. The International Code of Zoological Nomenclature (ICZN, 4th Edition, 1999) does not accept online texts as published work (Article 9.8); however, it accepts CD-ROM publications (Article 8). Euscorpius is produced in two identical versions: online (ISSN 1536-9307) and CD-ROM (ISSN 1536-9293). Only copies distributed on a CD-ROM from Euscorpius are considered published work in compliance with the ICZN, i.e. for the purposes of new names and new nomenclatural acts. All Euscorpius publications are distributed on a CD-ROM medium to the following museums/libraries: • USNM, United States National Museum of Natural History (Smithsonian Institution), Washington, DC, USA • AMNH, American Museum of Natural History, New York, USA • CAS, California Academy of Sciences, San Francisco, USA • FMNH, Field Museum of Natural History, Chicago, USA • MCZ, Museum of Comparative Zoology, Cambridge, Massachusetts, USA • MNHN, Museum National d’Histoire Naturelle, Paris, France • NMW, Naturhistorisches Museum Wien, Vienna, Austria • BMNH, British Museum of Natural History, London, England, UK • MZUC, Museo Zoologico “La Specola” dell’Universita de Firenze, Florence, Italy • ZISP, Zoological Institute, Russian Academy of Sciences, St. Petersburg, Russia • WAM, Western Australian Museum, Perth, Australia • NTNU, Norwegian University of Science and Technology, Trondheim, Norway Publication date: 7 July 2003 Euscorpius — Occasional Publications in Scorpiology. 2003, No. 7 Mesobuthus eupeus (C.L.

In addition, data on the variation of the number of pectinal teeth, and some ecological features of M. eupeus are provided.
