Synopsis

Caryedon gonagra (F.) is a beetle pest in ground nut kernels and occurs in this country in stored nuts. The karyotype has been investigated in both sexes. The chromosome complement of 2n = i8 includes a heteromorphic sex-determining pair—a large metacentric X and a small spherical Y. Particular attention has been paid to the sex bivalent in the male since study of this character alone may prove sufficiently diagnostic in species separation in closely related members of the Bruchidae.
