ABSTRACT

The present study reports the karyotypes of the following species of social wasps of the tribe Polybiini: Mischocyttarus (Monocyttarus) cassununga (n = 32); Mischocyttarus sp (n = 34); Metapolybia sp (n = 19); Polybia sp1 (n = 16); Polybia sp2 (2n = 34); Polybia (Myrapetra) occidentalis (2n = 34); Polybia (Trichothorax) sericea (n = 27); Protopolybia pumila (2n = 42); Protopolybia e. exigua (n = 31) and Parachartergus smithii (2n = 54). The chromosome numbers of this tribe are discussed in comparison with other social wasps.

Keywords: Karyotype; Social wasps; Hymenoptera.
