Megapulvinaria maxima (Green, 1904) View in CoL Figs 3e View Figure 3 , 4 View Figure 4 , 5b View Figure 5

Material.

K 1531, Thailand, Pai, on leaves and twigs of an undetermined dicotyledonous tree, 13.XI.2019, I.A. Gavrilov-Zimin.

New data.

2n = 20; bisexual reproduction with a Lecanoid heterochromatinization in male embryos. Incomplete ovoviviparity: embryogenesis (until the late anatrepsis) partially occurs inside of the mother’s body. Female reproductive system has the usual structure (Fig. 4 View Figure 4 ).

Comments.

Different European members of the tribe Pulvinariini have been previously studied cytogenetically ( Gavrilov 2007, Gavrilov and Trapeznikova 2008). Four Oriental species from the genera Chloropulvinaria Borchsenius, 1952, Pseudopulvinaria Atkinson, 1889 and Pulvinaria Targioni Tozzetti, 1866 were studied by Moharana (1990), who reported chromosome numbers with no comments or details. M. maxima is the first species of the genus Megapulvinaria Yang, 1982 studied in terms of chromosome number; the kartotype 2n = 20 is found for the first time in the tribe Pulvinariini in general.
