Originally ATTEMS (1895) described Atractosoma triaina from Styria (Austria), while VERHOEFF (1913a) described Ceratosoma regale from Bavaria (Königssee). He already pointed out the close relationship of both species but argued that these are different species due to Attems’ description. Even in the same year VERHOEFF (1913b) found two other populations of the same species complex, which he described as subspecies of regale: Ceratosoma regale ischliense from Bad Ischl and C. r. palfnerense from near Bad Gastein. In his faunistic publication about the myriapod fauna of the Eastern Alps, ATTEMS (1949) treated all taxa as subspecies of triaina, now under the genus name Asandalum, as it turned out that the name Ceratosoma was already preoccupied. The presently accepted genus name Ochogona was validated by HOFFMAN (1980). At present it is still unresolved if taxa cited above are only synonyms of triaina or represent separate species or subspecies. A revision including genetic data is urgently needed. At present genetic data is only available for regalis and ischliense, suggesting that at least ischliense is a synonym of regalis. Until a final revision it is better to keep the taxa regalis and triaina separate, as it has been done in KIME & ENGHOFF (2021). Consequently, the name Ochogona regalis has to be used for the populations of Germany and western Austria. Unfortunately, KIME & ENGHOFF (2021) included the O. regalis records also in their map for O. triaina. While O. regalis was formerly believed to reach its western border at the Inn Valley, a new record from the Karwendel Massiv extends the distribution further westward.
