Strumigenys filitalpa

Identification
Bolton (2000) - A member of the Strumigenys talpa-group. Most specimens examined have all hairs on the leading edge of the scape curved toward the scape apex, but a few have 1-2 curved toward the scape base. Because material of this species is so sparse I am unable to tell if this is normal variation or the result of hairs having been displaced during mounting, though I suspect the latter. For this reason filitalpa is run out twice in the key. See also under Strumigenys talpa.
