It has been quiet about European Euscorpiidae for awhile after several decades of many new genera and species from what was originally less than 10 species. Several new species have been described from many of the Greek islands, showing the importance of insular isolation and diversity.
Konstantinos Kalaentzis and co-workers have recently published an article describing a new species of Euscorpius Thorell, 1876 (Euscorpiidae) from the Greek island Rhodes based on morphological and molecular analysis.

Abstract:
The genus Euscorpius Thorell, 1876 comprises a diverse and taxonomically challenging group of scorpions in the Mediterranean, with Greece representing one of its principal centers of diversity. In this study, we provide an integrative description of Euscorpius diagorasi sp. n., a new species from Rhodes Island, Greece. The new species is described on the basis of adult male and female morphology and mitochondrial COI sequence data. It is a small oligotrichous species characterized by a total length of approximately 21–25 mm, pale yellow to light brown coloration with darker reddish-brown pedipalps, pectinal tooth count of 8 in the male and 7 in the females, Pv = 7–8, Pe-et = 5–6, and a distinct mitochondrial lineage. Phylogenetic analyses based on COI recovered the Rhodian specimens as a strongly supported monophyletic lineage, sister to E. vignai from Karpathos. Species delimitation analyses with BIN assignment, ABGD, and ASAP consistently supported the Rhodes population as a separate molecular unit. Morphologically, the new species differs from E. vignai and other geographically proximate Aegean and Anatolian congeners in a combination of body size, coloration, trichobothrial counts, pectinal tooth counts, carinal development and granulations. The species was found in pine forest habitat beneath the bark of Pinus brutia, suggesting an association with sheltered corticolous microhabitats. The description of E. diagorasi sp. n. adds to the growing evidence of insular diversification in Greek Euscorpius and highlights the still underestimated scorpion diversity of the Dodecanese.
