Planococcus kraunhiae (Kuwana)

( Fig. 49 , Plate 2 F , distribution map Fig. 69 L )

Dactylopius kraunhiae Kuwana, 1902: 55 . Planococcus siakwanensis Borchsenius, 1962a: 586 .

Field characteristics: Body elongate oval, coated with white mealy wax; dorsomedial area bare of wax; most wax filaments on body margins relatively short, straight.

Microscopic diagnosis: Slide-mounted adult female broadly oval. Anal lobes well developed. Antennae each with 8 segments. Legs normal, hind leg with translucent pores on coxa and tibia. Cerarii numbering 18 pairs; anal lobe cerarii each with 2 large conical setae, 1 auxiliary seta and a compact group of trilocular pores, all situated on a lightly sclerotized area. Anterior cerarii each with 2 large lanceolate-to-conical setae and 5‒7 trilocular pores. Cir- culus usually quadrate, divided by an intersegmental line. Ostioles well developed. Anal ring with 3 rows of pores and 6 setae. Cisanal setae shorter than anal ring setae.

Dorsum with long lanceolate-to-conical setae, like cerarrian setae but smaller, each with a swollen base and prominent collar. Multilocular disc pores absent. Trilocular pores and minute discoidal pores scattered throughout. Dorsal oral collar tubular duct groups sometimes present on submargins of posterior abdominal segments, but absent in Iranian specimens.

Venter with normal flagellate setae, longer than dorsal setae. Multilocular disc pores present around vulva, in single to double rows across posterior edges of median areas of abdominal segments III – VII, and in a single row across anterior edge of segment VII; 2 or 3 located on each margin of segments V – VII; absent from thorax and head. Oral collar tubular ducts of 2 sizes; smaller type occurring mainly across middle of abdominal segments; larger type sparsely scattered over median areas of thorax and in small groups on margins of head and thorax. Trilocular pores moderately numerous and evenly distributed .

Distribution: Planococcus kraunhiae is known from six countries in the Palaearctic Region including Iran, where it has been found in Tehran province ( García Morales et al. 2016, Moghaddam & Nematian 2020).

Host-plants: The species has been recorded on host-plants in 32 genera belonging to 25 families ( García Morales et al. 2016). In Iran, it has been found on Ficus retusa ( Moraceae ) ( Moghaddam & Nematian 2020).

Economic importance: None.

Natural enemies: None recorded from Iran.
