Remarks
- Systematics: The number of the quinquelocular pores is a subject to geographical and individual variation. In specimens from Tajikistan, these pores are always present and situated near the mouthparts, fore and middle coxae; occasionally singular pores are present on anterior abdominal segments. In specimens from Armenia, Kazakhstan, Turkmenia, and Yakutia, quinquelocular pores are always absent. In Georgian specimens these pores are also absent or singular pores occur near the mouthparts. (Danzig, 2006a) The synonymy is based on a comparison of the types. Ph. bicerarius differs from Ph. abditus in the absence of the quinquelocular pores, but this character varies between specimens. (Danzig, 2006a)
- Structure: Female. Body elongate, pink, up to 2 mm long. Antennae 9-segmented. Legs with slender segments, apices of tibiae with translucent pores. Circulus absent. Dorsal multilocular pores absent, or singular pores present on posterior abdominal segments. Ventral tubular ducts present on sternites VI-VIII. Quinquelocular pores not numerous or absent. (Danzig2006a)
- Biology: The species usually inhabits the valleys of the mountain rivers; in the Pamirs was found at an altitude of 2500 m in the wormwood saline deserts; in Yakutia was collected in pine forest. Mealybugs live under the leaf sheaths of Poaceae. (Danzig, 2006a)
- General Remarks: Good description of the adult female given by Borchsenius (1949) and by Tang (1992).Good description and illustration of the adult female given by Ter-Grigorian (1973) and by Tang (1992). Good description of the adult female given by Borchsenius (1949) and by Kosztarab & Kozár (1988F).
