The genus Laparus, with a single polymorphic species doris, probably an offshoot of early Heliconius, shows wide karyotypic variation (n = 20–30, 38) sometimes even within a single individual. The two most primitive genera also show much variation: Podotrkha has two species with n=9 and n = 26–29; and Philaethria shows many phenotypically similar species, two with n=29 and a still uncertain number (at least 3) with n = 88 (most common), 67–72 (most widespread), 62 (very restricted geographically), 52, 21, and 12. Several interspecific hybrids (Heliconius cydno × H. melpomene) showed normal chromosome pairing, while deficient pairing was seen in intersubspecific hybrids in Eueides tales and Heliconius sara. The importance of these results in the evolutionary study of polytypic tropical species is discussed. References Benson, W. W. 1971.
