DACETINE ANTS OF PANAMA: NEW RECORDS AND DESCRIPTION OF A NEW SPECIES (HYMENOPTERA: FORMIC1DAE: MYRMICINAE: DACETINI)

摘要

Pyrarnica and Strumigenys are the most speciose dacetine (Formicidae: Myrmicinae: Dacetini) genera in the world. A new ant species in the Pyramica alberti group is described from leaf-litter surveys conducted in the Canal Zone, Panama. Pyramica panamensis, new species, is similar to P. fridericimuelleri, P. nigrescens, and P. parsauga, but differs from those species in having strongly reduced eyes and a distinct promesonotal carina. A couplet is added to Bolton's (2000) key to Pyramica in order to accommodate the new species. New Central American records for two species in the dacetine genera Pyramica and one in Strumigenys are reported, and a checklist of the known Panamanian dacetine species is presented.
