DIAGNOSIS. Body of adult female broadly oval. Anal lobes moderately developed; anal lobe bar present extending anteriorly from bar seta. Antennae 8 segmented. Legs well developed. Translucent pores present on hind coxa, femur and tibia. Cerarii distinct, numbering 17 pairs. Anal lobe cerarii each with 2 conical setae, 3–5 auxiliary setae and a few trilocular pores, all situated on a membranous area. Anterior cerarii each with 2 shorter setae and normally 3–5 trilocular pores, except for head cerarii, which often have 3–5 conical setae; all without auxiliary setae. Circulus present, divided by intersegmental line. Ostioles well developed. Dorsal surface with short stiff setae; ventral surface with flagellate setae. Multilocular disc pores absent from dorsum; ventrally present posterior to vulva, medially in single rows on posterior edges of abdominal segments IV–VI and in more or less double rows along posterior edges of abdominal segment VII; a few also present on anterior edge of abdominal segment VII. Trilocular pores evenly dispersed on dorsum and venter. Discoidal pores minute, scattered. Dorsal oral rim ducts present singly next to most abdominal cerarii, plus 1 or 2 occasionally on thorax, plus a single duct present behind each frontal cerarius; 1 or 2 also present on midline of thorax and abdomen, and submedially on thorax. Ventral oral rim ducts absent. Oral collar ducts of 2 sizes on venter: large type, each about same width as a trilocular pore, present near posterior edges of posterior abdominal segments, and fairly numerous in marginal groups on head, thorax and abdomen, plus a group opposite each first coxa; small, slender ducts present mainly across middle of abdominal segments and medially on thorax.

DISTRIBUTION. Afrotropical, Oriental, Palaearctic: Iran. In Iran, P. burnerae occurs in Sistan & Balouchestan. It is known from 20 plant families worldwide (Ben-Dov et al., 2012).

MATERIAL EXAMINED. Sistan & Balouchestan: Chahbahar, Goater, 1 adult Ƥ, on Avecennia officinalis (Acanthaceae) , 9.v.2000. The host plant A. officinalis is new record for this mealybug.

COMMENTS. It seems that P. burnerae was accidently introduced into Iran. Goater is located on the border with Pakistan, where Iran meets the Oriental Region. This is the first record of this mealybug in Iran and Palaearctic region. The host plant A. officinalis is new record for this mealybug.
