| Reason for describing collection: | taxonomic analysis |
| Museum repositories: | SMNS |
| Collection method comments: The localities of the types of the new species cannot be specified in greater detail. The specimens were recovered in the first half of the 20th century from small temporary quarries which were opened in the Posidonia shale of the Holzmaden/Ohmden area. All of the quarries existed only for a short time and their exact positions are unknown today. | |
