Nothing is known about the biology of Strumigenys sibyna.

Identification

Bolton (2000) - A member of the Strumigenys scotti-group. The type-series of this species was included in Strumigenys scotti by Bolton (1983). The acquisition of more material and re-examination of the type-series of scotti showed that the two are not conspecific. The latter is currently known only from the Seychelle Islands and Madagascar (see under Malagasy fauna).
