Strumigenys memorialis

The type material was collected from a ground nest found in an open, grassy area with scattered pines. The colony contained a queen and 53 workers, with the nest consisting of a small chamber a few cm below the surface in clay soil, near the base of a large pine.

Identification
Bolton (2000) - A member of the Strumigenys pulchella-group. The pilosity of memorialis is distinctive in the pulchella-complex, especially its complete lack of elongate fine hairs and presence of quite dense short erect simple hairs on head and pronotum. Its possession of suberect short simple hairs on the tibiae is also unique as in other species these areas have short spatulate hairs that are decumbent to appressed.

Etymology
The specific epithet, translated "of remembrance." dedicates this species to Bill Brown in place of the more usual patronym. For some years Bill Brown had held an anlipathy toward patronyms. His main objection. as far as I can lell, was that patronyms often honor people who have only the most trivial association with the species bearing their name, and in the worst cases could be ass igned to stoke the egos of sponsors or patrons. I do not think these objections would apply in the case of an honoree who had made great and lasting contributions to our knowledge of a genus, especially when the name is applied posthumously. Nevertheless, I am respecting his feelings by avoiding a direct patronym.
