ABSTRACT

This report describes the karyotype of a Brazilian Diplopod species (Arthropoda), Sandalodesmus gasparae (Schubart, Acta Zool. Lilloana Inst. "Miguel Lillo" 2: 321-440,1944), collected from a termite mound Cornitermes bequaerti. This species has 2n = 12. The sex pair could not be distinguished.

Keywords: karyotype; termitophilic; Diplopoda.
