Strumigenys dayui

Identification
Xu & Zhou (2004) - Xu described and published as a new species in 2000, Bolton (personal communication) considered the names Strumigenys dayui and Strumigenys tisiphone represent the same species. After a careful comparison between the description of P. tisiphone and the holotype worker of E. dayui, we noticed that mandible of the latter without any preapical tooth or denticle, dorsal surface of mandible with only 2 longitudinal rows of scale-like to spoon-shaped hairs, and the measurements are distinctly larger than in the former. And therefore we considered as a valid species which closely related to P. tisiphone.
