Pandinus (Pandinus) trailini sp. n. from Ethiopia (Scorpiones: Scorpionidae), with Data on Localities and Life Strategy František Kovařík August 2013 — No. 163 Euscorpius Occasional Publications in Scorpiology EDITOR: Victor Fet, Marshall University, ‘[email protected]’ ASSOCIATE EDITOR: Michael E. 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 at: http://www.science.marshall.edu/fet/Euscorpius (Marshall University, Huntington, West Virginia 25755-2510, USA) ICZN COMPLIANCE OF ELECTRONIC PUBLICATIONS: Electronic (“e-only”) publications are fully compliant with ICZN (International Code of Zoological Nomenclature) (i.e. for the purposes of new names and new nomenclatural acts) when properly archived and registered. All Euscorpius issues starting from No. 156 (2013) are archived in two electronic archives: Biotaxa, http://biotaxa.org/Euscorpius (ICZN-approved and ZooBank-enabled) Marshall Digital Scholar, http://mds.marshall.edu/euscorpius/. (This website also archives all Euscorpius issues previously published on CD-ROMs.) Between 2000 and 2013, ICZN did not accept online texts as "published work" (Article 9.8). At this time, Euscorpius was produced in two identical versions: online (ISSN 1536-9307) and CD-ROM (ISSN 1536-9293) (laser disk) in archive-quality, read-only format. Both versions had the identical date of publication, as well as identical page and figure numbers. Only copies distributed on a CD-ROM from Euscorpius in 2001-2012 represent published work in compliance with the ICZN, i.e. for the purposes of new names and new nomenclatural acts. In September 2012, ICZN Article 8. What constitutes published work, has been amended and allowed for electronic publications, disallowing publication on optical discs. From January 2013, Euscorpius discontinued CD-ROM production; only online electronic version (ISSN 1536-9307) is published.

The new species is characterized by 6/4: 6-7/4: 7-8/4-5: 7-8/4-5 spination formula of tarsomere II and only two spines on the inclined anteroventral surface of tarsomere II; 16–18 ventral trichobothria on the chela; and sexual dimorphism, with the male having a more pronounced tooth on the movable finger of pedipalp than the female. A key to species and a distribution map of the subgenus Pandinus Thorell, 1876 are provided. Presented are also photos of localities. Introduction DIAGNOSIS. Total length 60–220 mm.
