Phenacoccus karkasicus Moghaddam sp. n.

( Fig. 28 )

Adult female

Described from 18 specimens in good condition.

Habit. On the leaf surface of Berberis vulgaris .

DIAGNOSIS. Mounted adult female oval, margin of body parallel, membranous, up to 4 mm long. Anal lobes well developed, each ventral surface with an apical seta 220–230 µm long. Antennae slender, 9 segmented, each about 550 µm long. Legs well developed; hind trochanter + femur 350–390 µm long, hind tibia + tarsus 440–450 µm long; claw about 40 µm long, with a small denticle. Ratio of lengths of hind tibia + tarsus to hind trochanter + femur 1:0.8–1.2. Ratio of lengths of hind tibia to tarsus 1:2.60–2.75, length of tibia more than 2.5 times length of tarsus. Translucent pores few, on hind coxa, femur and tibia. Anal ring 70–80 µm wide, bearing 6 setae, each about 200 µm long. Cerarii numbering 18 pairs. Anal lobe cerarii each with 4 enlarged lanceolate setae, longest about 22–23 µm long, and 8–12 trilocular pores; cuticle immediately next to setal collars lightly sclerotized. Anterior cerarii each with 2 smaller setae and 6–8 trilocular pores; frontal and preocular cerarii (C2) each with 3 setae; ocular cerarii (C3) with 4 setae and about 8 trilocular pores. Circulus present, usually with narrow lateral extensions; 230–250 µm wide, not divided by an intersegmental line. Both pairs of ostiole well developed, with inner edges of lips weakly sclerotized and each lip with 1–6 setae and a few trilocular pores

Dorsal surface with short lanceolate setae. Multilocular disc pores absent. Trilocular pores evenly distributed. Dorsal cerarii conspicuous, present in medial and submedial areas of thorax and abdominal segments, except segment VIII; each cerarius usually with 2 lanceolate setae, and 4 or 5 trilocular pores; median cerarii present on thorax and abdominal segments I–VII; submedian cerarii located on meso- and metathorax and on abdominal segments I–VI. Oral collar ducts numerous in wide bands across head, thorax and abdominal segments.

Ventral surface with normal flagellate setae in median areas, except short, lanceolate setae present around margins. Multilocular disc pores present medially on anterior and posterior edges of abdominal segments V–VII, along posterior edges of segments III and IV, and posterior to vulva. Quinquelocular pores numerous medially on head, thorax and anterior edges of abdominal segments. Trilocular pores evenly dispersed. Oral collar ducts of 2 sizes: large type as on dorsum, distributed around margins of thorax and abdomen; small type shorter than large type, mostly present across middle of abdominal segments, and on medial to marginal areas of thorax.

MATERIAL EXAMINED.

Holotype adult Ƥ. Iran. Esfahan, Kashan, Ghamsar, Sheikh Bahaii Dam, on Berberis vulgaris . ( Berberidaceae ), 15.v. 2011, 1955 m. (HMIM).

Paratypes, Iran. same data as holotype, 17 adult Ƥ (HMIM).

ETYMOLOGY. This species name is after the type locality, Karkas Montain, plus the Latin suffix '- icus' meaning 'belonging to'.

COMMENTS. P. k a r k a s i c u s Moghaddam sp.n. is similar to P. capensis Ferris (recorded in the Nearctic Region) in having: (i) medial and submedial dorsal cerarii, (ii) no dorsal multilocular disc pores, and (iii) ventral multilocular disc pores not reaching margins. P. k a r k a s i c u s differs from P. capensis in having (character states on P. capensis in brackets): (i) oral collar ducts in wide bands across of all dorsal segments (distributed sparsely); (ii) ventral multilocular disc pores on anterior and posterior edges of abdominal segments V −VII (posterior edges of abdominal segments V −VII only); and (iii) anal lobe and preocular cerarii each with 4 lanceolate setae (2 lanceolate setae).
