Description
Myrmica scabrosa

One worker syntype in. Without a locality label but with “scabrosa” in Smith’s handwriting, and with a Donisthorpe type-label. Donisthorpe (1932c) noted that two specimens were present in at that time. A very dirty specimen (now cleaned and remounted), identical to the syntype, was found in. I suspect that this specimen is the second syntype.
