Remarks

• Systematics: Ezzat (1960a) assigned this species in the genus Amonostherium stating that “this species could be easily distinguished from any other species in the genus Amonostherium by having six-jointed antennae and two pairs of prominent ostioles”. He noted that “the inclusion of the species in the genus requires some extension in the limits of the genus concerning the presence or absence of ostioles and the number of antennal joints”. Danzig and Gavrilov-Zimin (2014) transferred Amonostherium arabicum to the genus Phenacoccus Cockerell, 1893 stating that the species “is not related in our mind with the type (American) species of the genus Amonostherium, A. lichtensioides (Cockerell, 1897), but can be covered by the diagnosis of Phenacoccus. Since Amonostherium arabicum Ezzat, 1960a has a unique combination of characters that donot clearly fit in either of these genera without greatly expanding the concept of the genus, Evans & Abd-Rabou erected a new genus, Ezzatacoccus.
• Structure: Ezzatacoccus arabicus has 6-segmented antennae, 2 pairs of prominent ostioles, the dorsal setae short and spindle-shaped (as in other Phenacoccinae), ventral setae of 2 kinds with those along the submargin and margin short and spindle-shaped similar to the dorsal setae and those located medially long and flagellate, legs short but slender, multilocular pores present on the venter and dorsum, oral collar tubular ducts of 1 size, one size being more bulbous, one size more slender than the other but both are parallel sided.
