Pseudomyrmex subtilissimus ( Emery 1890) View in CoL

Pseudomyrma subtilissima Emery 1890:65 . Lectotype worker, Alajuela , Costa Rica (Alfaro) ( MCSN) [Examined] ,

Pseudomyrmex subtilissimus ( Emery 1890) ; Kempf 1972:224.

Worker diagnosis. - A member of the P. subtilissimus group, and immediately distinguishable from all other acacia-associated Pseudomyrmex by its small size (HW <0.60), elongate head (Cl <0.66), apedunculate petiole, and scarcity of standing pilosity. See Ward (1989:432) for further discussion of this species.

Distribution and biology. - P. subtilissimus has been collected only in Nicaragua and Costa Rica. What little is known about its biology suggests that it is a timid, non-protective species living in the thorns of Acacia plants occupied by (declining?) colonies of P. flavicornis .
