DIAGNOSIS. Body of adult female broadly oval. Anal lobes well developed. Antennae usually each 9 segments. Legs well developed; claws with a denticle. Translucent pores present on hind tibia. Cerarii numbering 18 pairs. Anal lobe cerarii each with 2 lanceolate setae and a few trilocular pores; anterior cerarii similar. Circulus usually oval, often sclerotized. Ostioles normal, with inner edges of lips only lightly sclerotized. Some dorsal setae occasionally with 1 or 2 trilocular pores situated near base. Dorsal multilocular disc pores absent; ventral multilocular disc pores present posterior to vulva and usually in a single row in median areas along posterior edges of abdominal segments IV –VII. Oral collar ducts absent on dorsum; ventrally, not numerous, medially across abdominal segments V –VII, anterior to multilocular disc pores; also with 1 or 2 tubular ducts usually present near margins of some posterior abdominal segments and posterior to each anterior spiracle.

DISTRIBUTION. Afrotropical, Australasian, Neotropical, Oriental, Palaearctic: Iran, Israel, Japan and Spain. In Iran, P. solani  occurs in Esfahan and Fars. It is known from 31 plant families worldwide (Ben-Dov et al., 2012).

MATERIAL EXAMINED. Esfahan: Esfahan, 9 adult Ƥ, on Festuca arundinacea  ( Poaceae  ), 24.ix. 2002 (B. Hatami). Fars: Shiraz, 14 adult Ƥ, on Chrysanthemum morifolium  ( Asteraceae  ), 6 adult Ƥ, Celosia cristata  ( Amaranthaceae  ), 1.ix. 2002 (Zibaii).

COMMENTS. The Solanum  mealybug has been reported in greenhouses on the roots of the ornamental plants in Iran, but no economic damage has been recorded. A survey on the endophytic fungus, Neotyphodium  spp., in Isfahan showed that this fungus is an effective biological control agent against some root-feeding pests, including P. solani (Hatami et al. 2006)  .
