( Fig. 36 , distribution map Fig. 68 K )

Phenacoccus arthrophyti Archangelskaya, 1930 .

Field characteristics: Body elongate or elongate oval, yellowish, about 2.5 mm long. Ovisac friable. Eggs and immature stages yellow ( Danzig 2006).

Microscopic diagnosis: Slide-mounted adult female oval to broadly oval. Anal lobes moderately developed. Antennae normally each with 8 segments. Legs well developed; hind legs without any translucent pores; claw with a small but distinct denticle; tarsal digitules pointed at tip and shorter than claw. Cerarii numbering 2 pairs. Anal lobe cerarii each with 2 small conical to lanceolate setae, 1 small seta and 6–8 trilocular pores; penultimate cerarii each with 2 setae and a few trilocular pores. Circulus absent. Anterior and posterior ostioles well developed.

Dorsum with lanceolate setae smaller than cerarian setae. Multilocular disc pores present across abdominal segments V–VII, and about 1 on each margin of segments III and IV. Trilocular pores evenly dispersed. Oral collar tubular ducts of 1 size, present in single row across thorax and abdominal segments.

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 each with about 12 loculi, present in transverse rows along posterior edges of abdominal segments IV – VII, and posterior to vulva. Quinquelocular pores present around mouthparts, thorax and medially on anterior abdominal segments. Trilocular pores evenly dispersed. Oral collar tubular ducts present, of 2 sizes: larger type similar to those on dorsum, present on thorax and laterally on abdominal segments, and smaller type distributed medially on posterior abdominal segments .

Distribution: Phenacoccus arthrophyti is known from six Palaearctic countries including Iran ( García Morales et al. 2016), where it has been recorded from Yazd province ( Moghaddam 2003).

Host-plants: This species has been recorded on host-plants in seven genera belonging to the families Amaranthaceae and Asteraceae ( García Morales et al. 2016) . In Iran, it has been recorded on Haloxylon sp. (Amaranthaceae) ( Moghaddam 2003).
