Cytogenetic and taxonomic studies of some legless mealybugs (Homoptera, Coccinea, Pseudococcidae)

Abstract. A new monotypic genus and species, Komodesia circuliplurima gen. et sp. n., from Flores Is. (Indonesia) and the new species, Antonina diversiglandulosa sp. n., from Southern Thailand are described and illustrated. Chromosomes of these species and also the ones of Antonina purpurea Signoret...

description Abstract. A new monotypic genus and species, Komodesia circuliplurima gen. et sp. n., from Flores Is. (Indonesia) and the new species, Antonina diversiglandulosa sp. n., from Southern Thailand are described and illustrated. Chromosomes of these species and also the ones of Antonina purpurea Signoret, 1872 and Antonina thaiensis Takahashi, 1942 are studied for the first time: 2n = 30, 20, 12 and 22+Bs correspondingly; the male embryos of all four species demonstrate Lecanoid paternal heterochromatinization of one haploid set of chromosomes. The karyotypes of three widely distributed species, Antonina pretiosa Ferris, 1953, Antonina graminis (Maskell, 1897) and Chaetococcus bambusae (Maskell, 1893), are studied based on material from other regions in comparison with previously published data. Photographs of the karyotypes are provided for the first time for all seven species. The terminological problems connected with the identification and naming of the three scale insect genetic systems, Lecanoid, Comstockioid and Diaspidoid, are discussed.
