Exallomochlus balouchestanensis Moghaddam, 2013a: 25–26 .

Field characteristics: Not recorded.

Microscopic diagnosis: Slide-mounted adult female nearly circular, membranous. Antennae each with 8 segments. Legs well developed; hind leg with translucent pores on ventral and dorsal surfaces of coxa and on dorsal surface of tibia; claw stout; tarsal digitules pointed at tip and shorter than claw. Cerarii numbering 18 pairs.Anal lobe cerarii each with 2 or 3 stout conical-to-lanceolate setae, 5 or 6 small slender setae and a concentration of trilocular pores, all situated at posterior end of a lightly sclerotized area occupying most of lobe. C 14 – 17 each bearing 3‒5 stout conical-to-lanceolate setae, and at most 1 small slender seta; C 6 – 13 each with 1 or 2 setae and without slender setae; and C 1–5 each with 3 or 4 setae. Circulus present, divided by an intersegmental line. Ostioles well developed. Anal ring situated on dorsum, a short distance from apex of body, the ring bearing 6 setae.

Dorsum with flagellate setae. Multilocular disc pores absent. Trilocular pores evenly dispersed. Discoidal pores circular, scattered. Oral collar tubular ducts absent.

Venter with setae similar to those on dorsum. Cisanal setae each 100–120 µm long, about same length as anal ring setae or longer, usually displaced onto dorsum posterior to anal ring. Multilocular disc pores each with 10 loculi, present posterior to vulva and in single or double rows medially across posterior edges of abdominal segments VI and VII, also in a single submedian row on posterior edge of segment V. Trilocular pores evenly dispersed. Discoidal pores similar to those on dorsum, scattered. Oral collar ducts each narrower than a trilocular pore, with a few submedially on segment V and across middle of segments VI and VII, also a few on segments VI–VII margins.

Distribution: Exallomochlus balouchestanensis is an Iranian species that has been recorded from Sistan & Balouchestan province ( Moghaddam 2013a).

Host-plants: The species has been recorded on Mangifera indica (Anacardiaceae) ( Moghaddam 2013a).

Economic importance: None.

Natural enemies: None recorded.

Genus FERRISIA Fullaway

Ferrisia Fullaway, 1923: 311 . Type species: Dactylopius virgatus Cockerell by monotypy and original designation.

Principal characters: Slide-mounted adult female elongate oval to broadly oval, membranous. Antennae normally each with 8 segments. Legs well developed, claw without a denticle. Cerarii present on anal lobes only. Circulus present, divided by an intersegmental line. Usually both pairs of ostioles well developed, but sometimes anterior pair lacking. Multilocular disc pores usually present on venter, few, near vulva and sometimes on abdominal segment VI. Dorsal tubular ducts large and elongate, each with the orifice surrounded by a flat sclerotized rim with 1‒4 setae within or near the margin and sometimes with associated discoidal pores.

Comments: Worldwide, 19 species are included in Ferrisia ( García Morales et al. 2016) ; one species is known from Iran (Moghaddam 2004).
