Taxonomic notes on Neotropical species in the genus Synemosyna

Two new species, Synemosyna edwardsi and S. maddisoni, and the previously undescribed male of S. decipens (O.P.-Cambridge) are described. The modified white setae (scales) in the genus are illustrated, S. americana (Peckham and Peckham) from Costa Rica, Mexico, and Panamañ and S. lauretta Peckham and Peckham, and S. lucasi (Taczanowski) from Peru are recorded. A review of the proposed models for the genus is discussed, and the formicid genus Crematogaster is suggested as a model for Synemosyna species with swollen opisthosomae.
