ABSTRACT

Cytogenetic studies of sphecid wasps are reported for the first time. Karyotype and C-band patterns are described for three species of the genus Microstigmus: M. arlei Richards (n=3, 2n=6), M. brasiliensis Melo (n=5, 2n=10), and M. luederwaldti Richards (n=3, 2n=6). Similarities between karyotypes of the species pertaining to different taxonomic groups are discussed.

Keywords: karyotypes; heterochromatin distribution; C-band; Microstigmus Wasps.
