( Fig. 8 , distribution map Fig. 66 G )

Chorizococcus pazoukii Moghaddam in Moghaddam & Alikhani, 2014.

Field characteristics: Not recorded.

Microscopic diagnosis: Slide-mounted adult female oval to broadly oval. Anal lobes poorly developed. Antennae each with 8 segments. Legs well developed, small for size of body. Hind leg with large translucent pores on dorsal surface of tibia; tarsal digitules pointed at tip and shorter than claw. Cerarii numbering a single pair situated on anal lobes, each cerarius with 2 large conical setae, 3 or 4 auxiliary setae and a group of trilocular pores, all situated on a slightly sclerotized area. Circulus divided by an intersegmental line. Ostioles well developed. Anal ring with 2 rows of pores and bearing 6 setae.

Dorsum with setae short and stiff. Multilocular disc pores absent. Trilocular and discoidal pores evenly distributed. Oral rim tubular ducts of 2 sizes: larger type numerous in bands over entire dorsum, except for abdominal segment VIII ; and smaller type present across posterior abdominal segments. Oral collar tubular ducts few, present on margins of abdominal segments IV ‒ VIII .

Venter with normal flagellate setae. Multilocular disc pores each with 12 loculi, present medially in more or less double rows at posterior edges of abdominal segments VI and VII, and posterior to vulva. Trilocular pores and discoidal pores present. Oral rim tubular ducts of 2 sizes: larger type, similar to those on dorsum, present over body except for posterior to vulva; smaller type present in marginal and submarginal zones. Oral collar tubular ducts, same as those on dorsum, present mainly around lateral margins of posterior abdominal segments and at posterior edges of abdominal segments III ‒ VIII .

Distribution: This Iranian species has been recorded from Markazi province ( Moghaddam & Alikhani 2014).

Host-plants: Chorizococcus pazoukii was found on the roots of an unknown plant ( Moghaddam & Alikhani 2014).

Economic importance: None.

Natural enemies: None recorded.

Comments: Chorizococcus pazoukii is similar to C. neomexicanus (Tinsley) in having numerous oral rim tubular ducts on the dorsum, but differs by lacking oral rim tubular ducts in medial areas of the venter.
