Strumigenys memorialis

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.
