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. 4View 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.
