Diagnosis

Adults. This species can be distinguished by the following combination of characters: tarsus I as long as or longer than tibia I, two of terminal setae on tarsus I longer than segment and all terminal setae serrated along entire length; members of ventral setae half as long as distance between them and longitudinally aligned.

Remarks

The identification of the South African specimens as P. ubiquitus   was based on reference material identified as such by the late Dr Smith Meyer. She studied the type specimens of P. ubiquitus   in 1970 and identified the South African specimens accordingly. At present the condition of the type material renders an examination impossible (Dr Ron Ochoa, personal communication). This species appears to be the dominant species in citrus orchards in southern Africa.
