Unaspis yanonensis ( Kuwana, 1923)

Material studied: 10 adult females, all from: CHINA, Guizhou Province, Qingyan city, on Citrus maxima (Burm) Merr. leaves, coll. Wei & Niu, 24.vii.2015 (at NWAFU: 2 slides each containing 4 adult females; and 2 slides each containing 1 adult female) .

Adult female diagnosis: Body elongate; segmentation obvious between prothorax and mesothorax, and between mesothorax and metathorax. Lateral margins of prepygidial abdominal segments protruding, those of segments II–III triangular; head rounded. Antennae each with minute, rounded tubercles and 1 seta. Anterior spiracles each with 12–15 parastigmatic pores; posterior spiracles each with 0–6 parastigmatic pores. Prepygidial abdominal segment lateral margins with gland spines, each side having 18–30 (6–9 on segment II, 8–10 on segment III, and 4–6 on segment IV). Conical duct tubercles numbering 7–9 on metathorax and 7–9 on abdominal segment I.

Pygidium slightly rounded, with 3 pairs of well-developed lobes. Median lobes somewhat sunken into pygidium, not close to each other. Second and third lobes similar to each other, each deeply bilobed with rounded lobules; third lobes sometimes slightly smaller than second lobes. Each side of pygidium with 4 single marginal gland spines: with 1 between median and second lobes, 1 between second and third lobes, 1 lateral to third lobe, and 1 on segment V.

Marginal macroducts absent from between median lobes, numbering 7 on each side: with 1 between median and second lobes, 1 between second and third lobes, 1 between lobules of third lobe, 2 on segment V and 2 on segment IV. Dorsal macroducts smaller than marginal ducts, present on all pygidial segments including VII and VIII, numbering over 100 in total. Anus rounded, rather small, situated near centre of pygidium. Perivulvar pores absent.
