NOTES ON THE GENUS SCYTODES

ABSTRACT. In this study we present a redescription ofScytodes championi, S. romitii and S, guttipes.
Seven species are newly described: S. panamensis from Panama; S. vaurieorum and S, chiquimula from
Guatemala; S. cogu and S. armata from Costa Rica; S. tegucigalpa and S. zamorano from Honduras.
Four of these were described as variations of 5'. championi in a recent revision of the species of Central
America. New records are presented for S. championi, S. romitii, S. guttipes, S. gertschi and S. cubensis.
