Nomenclatural History

• Ezzatacoccus Evans and Abd-Rabou 2023: 16. Type species: Amonostherium arabicum Ezzat by present designation . accepted valid name

Remarks

• Systematics: Species of Amonostherium are similar to Ezzatacoccus in that they have cerarii present on the anal lobes only, lack a circulus and have a claw denticle, but differ in that they have 7−8 segmented antennae, have either no ostioles or one pair of poorly developed ones on the abdomen, the dorsal setae flagellate, except for a few scattered spindle-shaped setae located medially, ventral setae similar in form and length, legs short and stout, multilocular pores present only on the venter and the oral collar tubular ducts of 2 sizes, one size more slender than the other but both are parallel sided. Ezzatacoccus 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. (Evans & Abd-Rabou, 2023)
• Structure: Body of adult female broadly oval, membranous; cerarii present only on the anal lobes membranous, poorly developed with rounded posterior margin, each cerarius consisting of 2 conical-shaped setae, about 4 trilocular pores and a short spindle-shaped seta; antennae 6-segmented; legs relatively short and slender, translucent pores present on the hind tibiae, claws with a small denticle; circulus absent; dorsum with two well developed pairs of ostioles; anal ring situated a short distance from the apex of the abdomen, bearing 3 pairs of relatively short setae, about as long as the anal ring; cisanal and obanal setae short, each about 15 um long; dorsal setae short, spindle-shaped, as in Phenacoccus species; ventral setae on lateral and sublateral margin similar to dorsal setae, medial setae of venter long and flagellate; multilocular pores scattered sparsely on both the dorsum and venter of the cephalothorax and abdomen; oral collar tubular ducts sparsely distributed on dorsum and venter each sclerotized with the anterior end slightly more bulbous.
