Remarks

• Structure: Adult female occurring on the stems of the host, beneath shelters of ants. "... enclosed in a dark-brownish or reddish sac, which is irregular in shape, circular to oval, usually broader behind, somewhat convex; typically with rounded, clear, shining, median, longitudinal ridge, bordered on each side by a pitted longitudinal groove of varying distinctness; all the surface except the median ridge covered over with white wax, which becomes thick and almost platelike along the margin, while varying in thickness in different spots dorsally ..." (Morrison, 1921).
• Biology: Morrison (1921) recorded this species in association with ants, Green (1930c) from nests of Dolichoderus carbonarius latisquama in Sumatra, while Takahashi (1929, 1950) reported that it was protected by Crematogaster rogenhoferi. The females of P. multipori exhibit complete ovoviviparity. The diploid chromosomal number is 18 in both sexes, and the karyotype consists of chromosomes gradually differing in size. Some cells contain additional small chromosomal elements, probably B-chromosomes, Several embryos demonstrated characteristic Lecanoid heterochromatinization of one haploid set of chromosomes. Since embryos with heterochromatinization are males, bisexual reproduction was presumed. (Gavrilov-Zimin, 2018a)
