Hadzibejliaspis stipae (Hadzibejli)

( Fig. 27 , distribution map Fig. 90J )

Exaeretopus stipae Hadzibejli, 1960: 310 . Hadzibejliaspis stipae (Hadzibejli) ; Koteja 1978: 318.

Field characteristics: Females feed on leaves, and produce an ovisac composed of thick, isolated waxy threads ( Koteja 1978).

Microscopic diagnosis: Slide-mounted adult female body oval to rather pear-shaped. Anal cleft very short.

Dorsum. Derm membranous. Setae spinose and mostly slightly curved, with narrow, blunt apices. Pores of 2 types: (i) small, circular and flat pore, scarce, possibly restricted to lateral areas of head; and (ii) similarly sized but slightly convex circular pores, each with a granulate surface and sometimes an inner filament, scattered throughout. Preopercular pores larger than simple pores, circular and convex, present in a narrow group anterior to anal plates, extending anteriorly to about metathorax. Duct tubercles absent. Tubular ducts each with outer ductule exceptionally wide with elongate ridges along its inner surface, present throughout, possibly most abundant on abdomen. Anal plates together subquadrate, longer than wide, each with 3 apical to subapical setae.

Margin. Usually lacking stigmatic clefts. Marginal setae spinose, similar to dorsal setae but larger, mostly curved; absent from margins of anal cleft; each side with about 14 setae between anterior and posterior stigmatic areas. Stigmatic setae not differentiated from marginal setae.

Venter. Derm completely membranous. Pregenital disc-pores mostly each with 7 or 8 loculi, present around anogenital fold and anteriorly on preceding 2 or 3 abdominal segments. Spiracular disc-pores each with 4 or 5 loculi, few, mainly restricted to cavity laterad of each peritreme, with 3 or 4 disc-pores in each cavity and with 1 or 2 pores anterolateral to each anterior spiracle. Pores of 2 types: (i) microducts present submarginally and probably throughout venter also; and (ii) submarginal simple pores. Tubular ducts of 2 types: (i) a duct type identical to dorsal tubular ducts, sparse throughout; and (ii) a smaller duct than type (i), but with a more concave cup-shaped invagination, present medially and submarginally on last 4 or 5 abdominal segments. Paired pregenital setae apparently absent; with 1 pair of large spinose setae and 3 pairs of slightly spinose setae present between antennal bases. Antennae each with 8 segments. Legs well developed, each with a distinct tibio-tarsal articulation and articulatory sclerosis. Claw without a denticle; claw digitules both narrow and longer than claw.

Distribution: Hadzibejliaspis stipae is only known from the Republic of Georgia and Iran ( García Morales et al. 2016), where it is found in Kermanshah province ( Torabi et al. 2010).

Host-plants: The species has been recorded on three host-plant species in the genus Stipa ( Poaceae ) ( García Morales et al. 2016). In Iran, it has been recorded on Poaceae ( Torabi et al. 2010) .

Economic importance: Not of any economic importance in Iran.

Natural enemies: Not recorded in Iran.
