Another new, subtroglophile scorpion species is described from Croatia, Euscorpius biokovensis sp. n. It is morphologically and ecologically similar to E. feti Tropea, 2013 but can be distinguished from the latter by a lower number of trichobothria (Pv = 8–9, with mostly 8, and usually et = 6) and pectinal teeth (usually Dp = 7 in males and 6 in females). The new species also has a more northern distribution although in some areas the two species overlap. E. biokovensis sp. n. has been found in more than 20 caves in Croatia, which makes it the most common Euscorpius species found in caves. It has also been found in Bosnia-Herzegovina. Ecological notes on this species are presented.
