Remarks

• Systematics: Slide-mounted adult female with: enlarged setae cylindrical, apices truncate, abundant along margin, all approximately same size, forming 3 longitudinal lines on each side of body; without protruding anal lobes; antennae 3-segmented; without pores or ducts; series of sclerotized areas scattered over dorsum (Green, 1926). This genus and species may not belong in the Eriococcidae. In 2016a, Hodgson & Williams agreed that the genus belongs to the family Eriococcidae (sensu lato) because the dorsal setae are spine-like although unusually bifid at the tip. Also microducts are present, quinquelocular pores are present at least on the venter, the setae on the legs are very few, the apical segment of each antenna is not swollen, the trochanteral pores are orientated transversely (not along the trochanter-femur articulation as in the family Pseudococcidae) and the anal ring possesses pores and six setae, all features found in most genera within the Eriococcidae. There is also an almost horizontal sclerotized bar with a pair of setae immediately anterior to the anal ring and this also is present in some genera of the Eriociccidae. Although Green (1926) considered that P. beesoni lacked pores and ducts, these are clearly present. The presence of the Burmese specimens within the galls of Beesonia dipterocarpi is particularly intriguing indicating that P. beesoni may have a wide distribution across the northern part of southern Asia on species of Dipterocarpaceae.
• Structure: Living adult female regularly ovate, dried specimens reddish (Green, 1926). Described by Beeson, 1941, probably from live material, as producing white cottony filaments but otherwise exposed. On bark Ramakrishna Ayyar (1930). Mounted specimens. Body oval, 1.3–1.4 mm long, 0.85–0.95 mm wide. Anal lobes absent.
• General Remarks: Most detailed description and illustration by Green (1926). Detailed redescription by Hodgson & Williams (2016a) Lectotype designated in Hodgson & Williams, 2016a. (BMNH): 1 slide with 5 adult females (condition fair-good; lectotype specimen that nearest the label “Type”). Also 2 further slides with identical labels, one with a single good specimen and other with 6 mainly poor specimens (including 3 very young adult females) (BMNH)
