Phenacoccus iranica Moghaddam sp. n.

( Fig. 29 )

Adult female

Described from 12 specimens.

DIAGNOSIS. Mounted adult female broadly oval, up to 2.88 mm long; anal lobes poorly or not developed, each ventral surface with an apical seta 140–150 µm long. Antennae slender, 9 segmented, each 390–420 µm long. Legs well developed; hind trochanter + femur 230–250 µm long, hind tibia + tarsus 250–270 µm long. Claws stout, about 25 µm long, with a distinct denticle. Ratio of lengths of hind tibia + tarsus to hind trochanter + femur about 1:1.08. Ratio of lengths of hind tibia to tarsus about 1:2.3. Translucent pores present on posterior surface of each hind tibia. Anal ring 60–63 µm wide, with 6 setae, each 97–100 µm long. Cerarii numbering 18 pairs. Anal lobe cerarii each with 2 lanceolate to conical setae, each about 15 µm long, plus 5 or 6 trilocular pores. Anterior cerarii each bearing 2 setae and about 2–4 trilocular pores; head and ocular cerarii (C3) with 3 setae and about 4 trilocular pores. Circulus present, well-produced laterally, 160–240 µm wide. Both pairs of ostioles well developed, inner edges of lips weakly sclerotized and each lip with 1–4 setae and a few trilocular pores.

Dorsal surface with short lanceolate setae, each mostly about 5 µm long. Multilocular disc pores absent. Trilocular pores evenly distributed. Oral collar ducts numerous, distributed in wide bands across head, thorax and abdominal segments.

Ventral surface with normal flagellate setae in median areas, and short, lanceolate setae around margins. Multilocular disc pore present medially and submedially, mostly in 1 or 2 rows on posterior edges of abdominal segments, along anterior and posterior edges of abdominal segment VII, and posterior of vulva. Quinquelocular pores numerous medially on head, thorax and all abdominal segments. Trilocular pores evenly dispersed. Oral collar ducts as on dorsum, present on head, thorax and abdominal segments.

Paratypes, IRAN. Kerman: same data as holotype, 2 adult Ƥ (HMIM). Baft, Torang, 23.v.2011, on A. cinerascens, 5 adult Ƥ (HMIM); Baft, Khabr National Park, Kaht, on A. cinerascens, 21.v. 2011, 2041 m., 3 adult Ƥ (HMIM). Kohgilouyeh & Boyer Ahmad: Yasuj, Tang –e Sorkh, Sartang, on A. circinnatum, 17.vii. 2010, 2107 m., 1 adult Ƥ (HMIM).

ETYMOLOGY. This species name is based on the type country, Iran.

COMMENTS. Phenacoccus iranica is similar to P. aceris in possessing: (i) numerous oral collar ducts on both ventral and dorsal surfaces, (ii) 18 pairs cerarii, (iii) ventral quinqulocular pores, and (iv) multilocular disc pores medially on ventral abdominal segments. P. iranica differs from P. aceris in having (character states on P. aceris in brackets): (i) only 1 circulus (2 circuli); (ii) many more oral collar ducts on head, both ventrally and dorsally (sparse); (iii) quinquelocular pores smaller than trilocular ducts (larger), and (iv) C18 with only 2 lanceolate setae, no short setae and 5 or 6 trilocular pores, these located on a membranous area (with lanceolate and slender setae, plus about 4 or 5 short setae and a concentration of trilocular pores, these located on a sclerotized area).

P. iranica is also similar to P. transcaucasicus Hadzibejli (Danzig 2003, 2006) in having: (i) circulus, (ii) 18 pairs cerarii and (iii) absence of dorsal multilocular disc pores. However, P. i r a n i c a differs from P. transcaucasicus in possessing (character states on P. transcaucasicus in brackets): (i) dorsal oral collar ducts present in wide bands across head, thorax and abdominal segments (dorsal oral collar ducts either absent entirely or present only in median areas of segments VI and VII).
