Ischnosoma spelaeum species group

A compilation of all the available records with specified localities, particularly recent records, casts considerable doubt on the validity of previous records from “Helenendorf” and some other records based on old material. According to the travel report by SCHNEIDER & LEDER (1878), the material from Helenendorf was collected in 1875 and subsequently processed and disseminated by Edmund Reitter. Based on the confirmed and more or less restricted distributions of I. myops , I. major , and particularly I. caucasicum (see Maps 1–2 ), Göygöl in Azerbaijan would be far outside the respective ranges and consequently implausible. Therefore, it appears likely that the material from “Helenendorf ” was either mislabelled or misidentified.
