Porphyrophora medicaginis Jashenko

Porphyrophora medicaginis Jashenko (Fig. 75, distribution map Fig. 92E) Porphyrophora medicaginis Jashenko, 1994: 22. Field characteristics: Body more-or-less egg-shaped; derm flexible and soft; long hair setae rather stiff; body light to dark red (Jashenko 1994). Microscopic diagnosis: Slide-mounted adult female with both surfaces of body quite densely covered by long hair-like setae and small setae.Antennae each with 7–9 segments; sensilla placodeum on segment IV usually present, circular or elliptical, containing about 5–7 small sensilla; other intermediate segments naked; apical segment slightly swollen, bearing some flagellate setae, several fleshy setae and sensilla. Prothoracic legs each with tarsus fused with claw, enlarged claw without a denticle. Each meso- and metathoracic leg with long pretarsus, 1/4 length of claw; meso- and metathoracic claws generally each constricted between claw and pretarsus. Thoracic spiracles each with peritreme containing 4–7 spiracular disc-pores, and texture of membranous peritreme with a mosaic pattern of diamond shapes; perispiracular sensilla situated far from margin of peritreme in a group of 2–7, occasionally with about 2 pores fusing to form a twin pore. Abdominal spiracles apparently absent. Anterior multilocular disc-pores each with 1 even or uneven ring of loculi, each ring mostly with 9–20 loculi; pores mainly present in transverse segmental bands 2 or 3 pores wide; some (not all) posterior multilocular disc-pores tending to be larger, particularly around genital opening, each of these generally with 2 or 3 rings of loculi. Anal opening with narrow, semicircular sclerotized rim along dorsal margin, surrounded by an area of derm without setae or pores. Distribution: Porphyrophora medicaginis is only known from Kazakhstan (Vostochno Kazakhstan Oblast) and Iran, where it has been found in Azarbaijan -e Sharghi and Kerman provinces (Jashenko 1994; Moghaddam, 2013). Host-plants: The species has been recorded on host-plants belonging to the families Fabaceae and Poaceae (García Morales et al. 2016). In Iran, the host-plants Medicago vulgare (Fabaceae), Cynodon sp. and Phragmites sp. (Poaceae) were recorded (Vahedi & Hodgson 2007). Economic importance: Porphyrophora medicaginis is of no economic importance in Iran. Natural enemies: None recorded in Iran.
