( Fig. 39 , distribution map Fig. 69 B )

Pseudococcus daganiae Bodenheimer, 1926: 191 ; Peliococcus armeniacus Borchsenius, 1949: 253 .

Field characteristics: Not recorded.

Microscopic diagnosis: Slide-mounted adult female oval. Anal lobe moderately developed. Antennae each with 9 segments. Legs well developed; tarsal and claw digitules all knobbed; hind legs without translucent pores; claw without a denticle; tarsal digitules pointed at tip and longer than claw. Circulus absent. Ostioles well developed. Cerarii numbering 18 pairs, mostly each with 2 conical setae and 2‒4 trilocular pores, but some with only 1 conical seta, and C 2 with 3 setae. Anal ring with 2 rows of pores and 6 setae.

Dorsum with short conical setae. Multilocular disc pores present in transverse rows on head, thorax and abdominal segments, and in groups of 2 or 3 ducts along margins. Trilocular pores and minute discoidal pores scattered throughout. Oral collar tubular ducts all of 1 size, scattered throughout.

Venter with normal flagellate setae, except for some short conical setae on margins. Multilocular disc pores each with 10 loculi, present across abdominal segments and on margins of thorax and head. Quinquelocular pores present in medial areas of body. Trilocular pores and minute discoidal pores scattered throughout. Oral collar tubular ducts of 2 sizes: smaller size present at posterior edges of abdominal segments V‒VIII+IX, and larger size present on margins of thorax and segments I‒IV.

Distribution: Phenacoccus daganiae is known from six Palearctic countries including Iran ( García Morales et al. 2016), where it has been recorded from Tehran province (Moghaddam 2015).
