Notes: [Special Issue: Proceedings of the ISSIS VIII International Symposium on Scale Insect Studies held at Wye College (U.K.), Aug. 31st - Sept. 6th, 1998.] Abstract only. Apiomorpha is a gall-inducing eriococcid genus which is endemic to Australia, where it is restricted to Eucalyptus. Females of most species induce large and spectacular galls which generally have species-specific morphologies. Apiomorpha is one of the most chromosomally diverse of all animal genera. Closely related species usually have very different karyotypes and there is extensive chromosomal variation between populations within most morphologically defined species. Some, but not all, of the karyotypic variation within morphospecies probably represents species-level differences. A phylogeny of Apiomorpha based on DNA sequence data has been proposed, onto which chromosomal and morphological traits have been mapped. Both fusion and fragmentation appear to be playing a role in chromosomal evolution in this genus.
