( Fig. 24 , distribution map Fig. 67 K )

Ripersia sacchari Green, 1900: 37 . Ripersia cellulosa Hall, 1923: 7 . Kiritshenkella stataria Borchsenius, 1948b: 583 . Pseudantonina fushanensis Borchsenius, 1958: 158 . Kiritshenkella shirakensis Hadzibejli, 1960a: 57 .

Field characteristics: Not recorded.

Microscopic diagnosis: Slide-mounted adult female elongate oval to oval. Antennae each with 6 segments. Legs well developed but small for size of body; hind coxa larger than anterior coxae, without anterior margin, but with large translucent pores on both ventral and dorsal surfaces, those on ventral surface extending onto adjacent derm; tarsal digitules pointed at tip and longer than claw. Cerarii present on anal lobes only, each containing 2 slender conical setae placed close together on a membranous area, not associated with trilocular pores. Circulus absent. Ostioles represented by poorly developed posterior pair only. Anal ring with 3 or 4 rows of pores and 6 setae.

Dorsum with short, slender setae, longest seta situated on abdominal segment VII. Multilocular disc pores numerous on head, thorax and abdominal segments. Trilocular pores present in median zone from prothorax to segment VIII. Discoidal pores minute, scattered. Oral collar tubular ducts each with a wide conical- to flangeshaped internal collar and short ductules, numerous around margins.

Venter with flagellate setae. Multilocular disc pores each with 10 loculi, present around marginal areas and across head, thorax and abdominal segments. Trilocular pores present near midline, extending posteriorly from mesothorax to about segment VII. Discoidal pores minute, scattered. Oral collar ducts same as those on dorsum, numerous around margins, extending to submedian areas on segments IV–VII.

Distribution: Kiritshenkella sacchari is known from 14 countries in the Oriental and Palaearctic Regions including Iran ( García Morales et al. 2016), where it is found in Khouzestan province ( Moghaddam 2009a).

Host-plants: The species is mainly found on Poaceae but has been recorded on host-plants in 11 genera belonging to three families: Cyperaceae , Poaceae and Simaroubaceae ( García Morales et al. 2016) . In Iran, it has been recorded on Saccharum officicnarum (Poaceae) ( Moghaddam 2013b).

Economic importance: None.

Natural enemies: None recorded in Iran.

Genus MACONELLICOCCUS Ezzat

Maconellicoccus Ezzat, 1958: 380 . Type species: Phenacoccus hirsutus Green by original designation.

Principal characters: Slide-mounted adult female broadly oval, membranous. Antennae usually each with 9 segments. Legs well developed, claw without a denticle. Partial or complete anal lobe bar present, sometimes faint. Cerarii numbering at most 6 pairs, all on posterior abdominal segments, each cerarius with at most 1 pair of conical setae, with or without trilocular pores, and without auxiliary setae. Circulus present or absent. Ostioles present or absent. Dorsal and ventral setae flagellate. Multilocular disc pores present on venter. Oral rim tubular ducts present on dorsum and venter, each sometimes with an obscure rim. Oral collar tubular ducts present on venter, sometimes present on dorsum.

Comments: Worldwide, eight species are included in Maconellicoccus ( García Morales et al. 2016) ; one species is known from Iran ( Fallahzadeh et al. 2002).
