Erect hair moderately abundant, flexuous, with little or no underlying appressed pubescence; petiole clavate, without distinct peduncle and node; eye with 39-48 facets; propodeal spines long; mesosomal dorsum with thick wavey rugae; WL 0.81-0.90mm.
Notes
Kugler (1994) reported collections by Longino from Corcovado National Park, including numerous foragers from the ground and low vegetation, a worker in a nest of Cyphomyrmex salvini, and another at the base of a tree amongst Pheidole workers. Longino twice collected workers at extrafloral nectaries of Passiflora pittieri in Corcovado. L. Garling collected a nest at La Selva Biological Station: a "tubular entrance with white 'fuzz'" in a cacao tree. New collections by Longino reported here are Winkler samples from Carara, Hitoy Cerere, La Selva, Monteverde (1100m on Pacific slope), Turrialba, Sirena, and San Vito. At La Selva, Longino observed a lone queen low on a tree trunk at night.
