description: Coccus pseudomagnoliarum (Kuwana)
(Fig. 19, distribution map Fig. 89J)
Lecanium (Eulecanium) pseudomagnoliarum Kuwana, 1914: 7. Coccus pseudomagnoliarum (Kuwana); Clausen 1923: 225.
Field characteristics: Live adult female elongate oval, slightly convex; immatures greenish or greyish, with light or dark yellow mottling; dorsum of young adult female grey mottled with dark brown, older specimens mottled with dark grey.
Microscopic diagnosis: Slide-mounted adult female body oval, with distinct stigmatic clefts. Anal cleft of moderate depth.
Dorsum. Derm membranous on young females, old females show a few small, pale areolations. Setae short, each sharply pointed, scattered. Microducts, each in an areolation, present throughout. Preopercular pores numbering 4−12, present in relatively long group extending from anterior to anal cleft to first abdominal segment. Small simple pores few, scattered throughout. Tubular ducts and duct tubercles absent. Anal plates together quadrate, each plate with 4 apical setae. Anal ring with 8 setae.
Margin. Marginal setae curved or straight, with simple pointed or spatulate apices, numbering 14−21 between anterior and posterior spiracular clefts on each side. Stigmatic clefts very shallow, each containing 3 stigmatic setae, with median seta 2 or 3 times longer than a lateral seta.
Venter. Derm entirely membranous. Pregenital disc-pores usually each with 7‒10 loculi, present in a sparse group around anogenital fold, with fewer mediolaterally on preceding abdominal segments. Spiracular disc-pores each with 5 loculi, present in single row between each spiracle and margin. Simple microducts small and sparse, present throughout. Ventral tubular ducts each with a long narrow inner ductule ending in a terminal gland, a few present on submarginal areas of posterior abdomen, absent from near coxae. Three pregenital segments each with a pair of long setae. Antennae each with 8 segments. Legs well-developed, each without a distinct tibio-tarsal articulatory sclerosis; claw with a denticle (not illustrated); claw digitules both broad; tarsal digitules longer than claw digitules.
Distribution: Coccus pseudomagnoliarum is known from 22 countries in the Australian, Nearctic, and Palaearctic regions (García Morales et al. 2016); in Iran, it is found in Gilan and Golestan provinces (Kaussari 1946).
Host-plants: The species has been recorded on host-plants in 19 genera belonging to 16 families (García Morales et al. 2016) but favours Rutaceous hosts, particularly Citrus species. In Iran, it has been found on Citrus sinensis (Rutaceae) (Kaussari 1946).
Economic importance: Not of any economic importance in Iran.
Natural enemies: None recorded in Iran.
Comments: No material of C. pseudomagnoliarum has been studied for this work.
