Material.

K 939, Indonesia, Bali, mountain forest above Lake Buyan, about 1200 m altitude, on leaves of an undetermined tree, 13.XI. 2011, I.A. Gavrilov-Zimin.

New data.

2n = 18; there is no heterochromatinization (and thus no Lecanoid system) in all 50 studied embryos from 3 females, no sperm in spermathecae and no males in the studied population; so, the thelytocous reproduction is characteristic of this species. Complete ovoviviparity. Female reproductive system is of the usual for the soft scales type (Fig. 4 View Figure 4 ).

Comments.

The type species of the genus, Coccus hesperidum   Linnaeus, 1758, shows 2n =14 and different variants of parthenogenesis ( Thomsen 1927, 1929, Nur 1979), whereas two other studied species, C. longulus   (Douglas, 1887) and Coccus   sp., were reported by Moharana (1990) as having 2n=18, but without any comments on genetic system and reproductive peculiarities . All other (more than 110) species of the genus Coccus   Linnaeus, 1758, are still unstudied cytogenetically.
