Original Description:

Strumigenys alberti Forel 1893:380. Syntype worker, queen: Antilles Islands, St. Vincent.

Later moved to Smithistruma, then Pyramica. See Bolton (2000) for complete synonymy.

Natural History:

This species occurs in wet forest habitats. Colonies are small, and are encountered beneath dead wood, under loose bark, and in plant cavities. Members of the genus are all predaceous, with a static pressure mode of attack (Bolton 1999).

This is one of the most common Pyramica in Costa Rica. At La Selva Biological Station, nests are common in small pieces of dead wood on the ground. For example, old Lecythis pods are common nest sites. Workers are slow-moving, and thus relatively easy to overlook. Individuals can be obtained by sifting leaf litter and extracting arthropods in a Berlese funnel or Winkler bag.
