Porphyrophora jashenkoi Vahedi

( Fig. 74 , distribution map Fig. 92D )

Porphyrophora jashenkoi Vahedi 2007 in Vahedi & Hodgson, 2007: 68.

Field characteristics: Appearance of live specimens not recorded.

Microscopic diagnosis: Slide-mounted adult female oval; dorsal and ventral surfaces of body covered quite sparsely by long hair-like setae and small setae, although setae on margins of head and prothorax more numerous. Antennae each with 7 segments; sensillum placodeum on segment IV usually present, containing a dense group of 3–5 small sensilla, also with a short seta (not illustrated); segment V with a minute seta; other intermediate antennal segments naked; apical segment as wide as, or slightly wider than long, bearing some flagellate setae, several fleshy setae and sensilla. Prothoracic legs each with tarsus fused with claw; enlarged claw at least 2.0x longer than basal width, without a denticle. Thoracic spiracles each with an apodeme; each peritreme with 4–6 spiracular disc-pores; each pore with 1 ring of about 8 evenly-spaced loculi; each disc-pore with a bright central zone; with a group of 2 perispiracular sensilla on lateral margin of peritreme. Abdominal spiracles apparently absent. Multilocular disc-pores very sparse, each pore with a single ring of 8–10 loculi; mainly present in segmental transverse bands 1 or 2 pores wide; posterior multilocular disc-pores tending to be larger, these almost always with 1 or 2 complex rings of loculi. Microducts abundant over dorsum of abdomen (not illustrated). Anal opening with thin, semicircular, poorly sclerotized rim on dorsal margin, surrounded by an area of derm without setae or pores.

Distribution: Porphyrophora jashenkoi is known only from Iran, Hamadan-Kermanshah province ( Vahedi & Hodgson 2007).

Host-plants: The species was recorded feeding on wheat, Triticum aestivum ( Poaceae ) ( Vahedi & Hodgson 2007).

Economic importance: Porphyrophora jashenkoi is no economic importance in Iran, but might become a problem on wheat if accidentally introduced to other parts of the world.

Natural enemies: None recorded in Iran.
