( Fig. 37 , distribution map Fig. 68 L )

Phenacoccus betae Moghaddam, 2010a: 65–67 .

Field characteristics: Not recorded.

Microscopic diagnosis: Slide-mounted adult female broadly oval. Anal lobes poorly developed. Antennae each with 9 segments. Legs well developed; translucent pores small and difficult to observe, present on hind femur and tibia; claw with a small but distinct denticle; tarsal digitules pointed at tip and shorter than claw, Cerarii numbering 7 pairs, with 4 on head (C 1–4) and 3 on the posteriormost abdominal segments (C 16–18). Anal lobe cerarii each with a pair of lanceolate setae and 4 or 5 trilocular pores. Anterior cerarii each with 2 small lanceolate setae and 2 or 3 trilocular pores. Preocular cerarii (C 3) with 3 lanceolate setae. Circulus absent. Ostioles well developed.

Dorsum with lanceolate setae smaller than cerarian setae. Multilocular disc pores present across posterior edges of abdominal segments V−VII. Oral collar tubular ducts all same size, scattered on head, thorax and abdominal seg- ments, but absent from segment VIII.

Venter with setae of 2 types: slender hair-like setae present medially on head, thorax and abdomen; and spinelike setae present on submargin and in marginal rows. Multilocular disc pores eac with about 10 loculi, present in 2 or 3 rows across posterior edges of abdominal segments IV−VII, on anterior edge of segment VII, on margin of segment III, and posterior to vulva. Quinquelocular pores present around mouthparts only. Trilocular pores evenly dispersed. Oral collar tubular ducts of 2 sizes: larger ducts, same as on dorsum, distributed on head, thorax and margins of abdominal segments; and smaller ducts present medially on posterior abdominal segments .

Distribution: Phenacoccus betae is known only from Iran, Kermanshah and Markazi provinces ( Moghaddam 2010a).

Host-plants: The species has been recorded on the host-plants Amaranthus blitoides (Amaranthaceae) and Beta vulgaris (Betulaceae) ( Moghaddam 2010a).
