Abstract Phenacoccus peruvianus Granada de Willink, 2007, Ph. prope avenae Borchsenius, 1949, Ph. hordei (Lindeman, 1886), Вalanococcus boratynskii Williams, 1962, Trionymus  radicum (Newstead, 1895), Rhizoecus halophilus (Hardy, 1868) were studied karyologically for the first time. All species demonstrate 2n=10 and a Lecanoid genetic system. Photos of karyotypes of all studied species are given.
