Diagnosis of the genus. After Weiner (1996) and Pomorski (1998) the genus Protaphorura is characterized by following characters: hind margin of head with pso, PAO with numerous simple vesicles oriented perpendicularly to long axis of the organ in its central part, d0 on the head dorsally absent, ms on Ant. IV in the middle of posterior half of segment, Th. I without pso, Th. II–III with lateral ms, Abd. VI with anal spines on distinct papillae or with small spines without papillae, furca reduced to cuticular fold with 2+2 or 1+1 chaetae, distal verticil of Tita with 11 chaetae and male ventral organ present or absent. AOIII mostly with 5 papillae, some recently described species have only 4 papillae ( Gulgenova & Potapov 2013). Labium is of A-type, i.e. with blunt tipped terminal sensillum on papilla A ( Fjellberg 1998b) but this character seems to be variable within the genus. For instance, P. janosik from Slovakia (caves) has all papillae with acuminate terminal sensilla.
