( Fig. 41 , distribution map Fig. 69 D )

Phenacoccus insularis Danzig, 1971: 378 . Phenacoccus iranica Moghaddam, 2013a: 54‒55 .

Field characteristics: Not recorded.

Microscopic diagnosis: Slide-mounted adult female broadly oval. Anal lobes poorly or not developed. Antennae slender, each with 9 segments. Legs well developed; hind leg with translucent pores on dorsal surface of tibia; claw stout, with a distinct denticle; tarsal digitules pointed at tip and shorter than claw. Cerarii numbering 18 pairs. Anal lobe cerarii each with 2 lanceolate-to-conical setae and 5 or 6 trilocular pores. Anterior cerarii each bearing 2 setae and about 2–4 trilocular pores; head and ocular cerarii (C 3) each with 3 setae and about 4 trilocular pores. Circulus present, produced laterally, not divided by intersegmental line. Ostioles well developed, with inner edges of lips weakly sclerotized, each lip with 1–4 setae and a few trilocular pores.

Dorsum with short lanceolate setae. Multilocular disc pores absent. Trilocular pores evenly distributed. Oral collar tubular ducts numerous, distributed in wide bands across head, thorax and abdominal segments.

Venter with normal flagellate setae in median areas, and short lanceolate setae around margins. Multilocular disc pores each with 10 loculi, present medially and submedially, mostly in single or double rows on posterior edges of abdominal segments I‒VIII, and posterior to vulva. Quinquelocular pores numerous medially on head, thorax and segments I–VIII. Trilocular pores evenly dispersed. Oral collar ducts, same as those on dorsum, present on head, thorax and segments I–VIII + IX.

Distribution: Phenacoccus insularis has been recorded from Romania, Russia and Iran; in Iran it has been found in Kerman and Kohgilouyeh & Boyerahmad provinces ( Moghaddam 2013a).

Host-plants: This species has been recorded on host-plants in nine genera belonging to six families; in Iran it occurs on Acer cinerascens (Sapindaceae) ( Moghaddam 2013a).

Economic importance: None.

Natural enemies: None recorded.

Comments: Phenacoccus insularis has an anvil-shaped circulus, a characteristic often found in Phenacoccus species native to the New World, e.g., P. solenopsis .
