Remarks
- Systematics: Diaspis quercus is close to D. syriaca in having: (i) median lobes (L1) forming a deep notch at apex of pygidium; (ii) dorsal submarginal ducts on abdominal segments II–V present in groups; and (iii) gland spines on segments V–VII spinelike, with simple tips. It differs from D. syriaca as follows (character states on D. syriaca in brackets): (i) dorsal median duct absent from between median lobes (present), (ii) dorsal submarginal and submedian ducts on abdominal segment III forming a continuous group (ducts in two distinct groups); (iii) dorsal submedian ducts absent from metathorax and abdominal segments I and II (ducts present); and (iv) anal opening often situated near centre of pygidium (opening situated at about apical 1/5th of pygidium). (Moghaddam, 2021)
- Structure: Slide-mounted adult female body broadly oval (1.15–1.18 mm long and 0.80–0.83 mm wide). Cuticle membranous, except for parts of pygidium. Antennae each with 1 long, strong seta. Each anterior spiracle with 5 associated trilocular disc pores; posterior spiracles without associated disc pores. Thoracic tubercles absent. Pygidium with 5 pairs of lobes. Median lobes (L1) forming a deep notch at margin, divergent, each with inner margin longer than outer margin; median lobes apparently without setae, and separated by space 1.6 times width of median lobe, without yoke. Second lobes (L2) well developed, bilobed and slightly divergent; inner lobules (L2a) rounded at apex and larger than L1; outer lobules (L2b) much smaller but conspicuous and almost conical. Third lobes (L3) bilobed, L3a and L3b both well developed. Fourth lobes (L4) almost flat, each formed of 3 low, sclerotised prominences. Fifth lobes (L5) inconspicuous, almost flat but sclerotized. Anal opening situated 6 times length of anal opening from base of median lobes, anal opening 14 μm long (the anal opening not visible in the second specimen). Gland spines each spiniform and swollen at base, numbering 7 pairs on each side; gland pines present in pairs between L1 & L2, L2 & L3 and L3 & L4, and 1 gland spine present on segment V.
