Remarks

• Systematics: Danzig (2006a) compared the junior synonym, Ph. trichonatus, to other species of this genus and stated that it differed in the presence of flagellate setae on the dorsum. (Danzig, 2006a) Danzig & Gavrilov-Zimin, 2014 determined that upon comparison of Coccura triconota with the original description and figure of Phenococcus rotundus that the species were conspecific.
• Structure: Adult female body broad-oval, orange, up to 3 mm. Antennae 9-segmented. Circuli 2 or 3 in number. Multilocular pores present on abdominal sternites only, numerous. (Danzig, 2006a)
• Biology: Usually occurs on subterranean parts of the trunk and shoots and thick roots; above ground found only in fissures and wounds under the bark where their presence is betrayed by ants which cover the mealybugs with pieces of masticated wood. Ants tend colonies of Ph. trichonotus and build galleries from masticated wood over them. (Danzig, 2006a)
