The karyotype of Psoraleococcusmultipori (Morrison, 1921) was studied for the first time, based on material from Indonesia (Sulawesi). The diploid chromosome number was found to be 18 in both males and females, but some cells contained also additional small chromosomal elements, probably B chromosomes. About 50 % of the studied embryos demonstrated paternal genome heterochromatinization of one haploid set of chromosomes (PGH) suggesting presence of a Lecanoid genetic system. The embryos with PGH are known to be always the male embryos in scale insects and so, bisexual reproduction may be presumed for P.multipori. The information provided represents the first probative cytogenetic data for the subfamily Lecanodiaspidinae Targioni Tozzetti, 1896 as a whole. A detailed morphological figure and photos of female and male embryonic cells are given. Additionally, it was discovered that the females of P.multipori exhibit complete ovoviviparity.

Lecanodiaspidinae（Homooptera，Coccinea，Asterolecaniidae sl）的染色体和遗传系统的第一个插图。

基于印度尼西亚（苏拉威西）的资料，首次研究了多孢假球菌的核型（Morrison，1921）。发现男性和女性的二倍体染色体数均为18，但是某些细胞还包含其他小的染色体元素，可能是B染色体。大约50％的受研究胚胎表现出一组单倍体染色体（PGH）的父系基因组异染色质，表明存在类Lecanoid遗传系统。已知具有PGH的胚胎在鳞翅目昆虫中一直是雄性胚胎，因此，可以推测双歧杆菌的双性生殖。提供的信息代表了Lecanodiaspidinae Targioni Tozzetti家族的整体第一个证明性细胞遗传学数据，1896年。给出了详细的形态图和雌性和雄性胚胎细胞的照片。
