Spilococcus mirzayansi (Moghaddam)

( Fig. 57 , distribution map Fig. 70 H )

Chorizococcus mirzayansi Moghaddam, 2010a: 64‒65 .

Field characteristics: Not recorded.

Microscopic diagnosis: Slide-mounted adult female broadly oval. Anal lobes moderately developed. Antennae each with 8 segments. Legs well developed; hind leg with large translucent pores on coxa and tibia; claw with a small denticle; tarsal digitules pointed at tip and shorter than claw. Cerarii numbering 8 pairs, all situated on abdominal segments; anal lobe cerarii each with 2 small slender conical setae, 3 or 4 auxiliary setae and a group of trilocular pores. Anterior cerarii (C 14‒17) each with 2 smaller conical setae, no auxiliary setae and a small concentration of trilocular pores; C 11‒13 each with 1 conical seta and 2 or 3 trilocular pores. Circulus absent. Ostioles well developed. Anal ring normal, with 6 setae.

Dorsum with short conical setae. Multilocular disc pores absent. Trilocular pores present. Discoidal pores minute, scattered. Oral rim tubular ducts arranged in single rows across abdominal segments, except segment VIII, and a few scattered over thorax and head. Oral collar ducts present in marginal groups on segments II–VII.

Venter with long flagellate setae, and slender conical setae near margins. Multilocular disc pores present posterior to vulva, in double rows across medial posterior edges of abdominal segments VI and VII, and in a single row on posterior edges of segments III–V; also present along anterior edges of segments V–VII, reaching to margins; a few multilocular disc pores also present in submedial area of segment II. Trilocular pores present. Discoidal pores minute, scattered. Oral rim ducts similar to those on dorsum, present along margins of abdominal segments, and across head and thoracic segments. Oral collar ducts occurring mainly in groups in lateral areas of segments III–VIII and across segments III–VII; also present in a small group lateral to each anterior coxa.

Distribution: Spilococcus mirzayansi has been recorded only from Tehran Province, Iran ( Moghaddam 2010a). Host-plants: On Opuntia ficus-indica (Cactaceae) ( Moghaddam 2010a). Economic importance: None. Natural enemies: None recorded.
