Labrada and C. Prieto in Schönhofer (2013), "Establishment of the present-day taxonomy and validating species-specific characters in ''Ischyropsalis'' have been mainly facilitated by the thorough revision of Martens (1969). Having been unable to borrow many types from the Iberian Peninsula, part of his work remained hypothetical for that local fauna, which was later corrected by Dresco (e.g. 1970, 1972), Luque (1991, 1992) and Prieto (1990a, 1990b). Of the 42 species described or emended by Roewer (1914, 1916, 1923, 1950, 1953a) only two remain valid."
