(Figs. 34–63)
Material examined. Holotype adult ♀: CHINA: Guizhou Prov., Jiangkou County, Fanjing Mountain, N 27º 91’ 01”, E 108º 69’ 85”, 1700 m altitude, on Schima superba (Theaceae), / 15 November 2019, / Feng Tian, Xinyi Zheng & Lan Zhang leg., mounted singly on a slide (GUGC)
Paratype ♀♀: Same data as holotype, 12 ♀♀ mounted singly on slides (GUGC).
Description. Slide-mounted adult female (n=13): Body 1190–1340 (1267) µm long, 680–780 (745) µm wide; prosoma swollen, slightly broader than postsoma, margin tending to be ovate, with prosomatic tubercles indiscernible; pygidial margin slightly rounded. Prosoma with anterior margin broadly rounded; broadest at mesothorax, with posterolateral mesothoracic margin enlarged, rounded, and basally slightly constricted; metathorax narrower than mesothorax. Abd. I very slightly narrower than metathorax; abd. II with lateral margins protruding, almost as wide as metathorax; posterior abdominal segments tapering towards body apex.
Prosoma. Antennae separated by half width of clypeus, 85–90 µm; each antenna composed of a small tubercle bearing 1 seta and 1 sclerotised spine. Anterior spiracles each associated with 18–25 trilocular disc pores; posterior spiracles each with 1–9 disc pores (usually 1–4).
Pygidial lobes. Lobes numbering 3 pairs; L 1 mostly sunken into apex of pygidium, base of each L 1 with a mesad linear extension onto ventral derm, these extensions separated from each other by a narrow space; L 1 elongate and divergent, minutely serrate on diverging mesal margins, blunt or roundish apically, lobe apices separated by 20–24 µm. Without setae or gland spines between median lobes. L 2 and L 3 well developed, bilobulate. Pore prominences and marginal processes on abd. IV and V margins each almost as long as nearby lobes, the processes minutely serrate.
Ducts. Submedian dorsal macroducts present on abd. II–VI, II and III each with 2 rows; II with front row of 1–4 ducts, rear row 1–4; III with front row 2–4, rear row 4; abd. IV–VI each with a single row; IV with 4 or 5 ducts; V with 4; and abd VI with 1–3, usually 2. Submarginal dorsal macroducts present on abd. II–V: II with a single row of 0–4 ducts; III with 3–6; IV with 4; V with 4. Lateral macroducts occurring on abd. II and III, II with 7–9 ducts and III with 10 or 11. Marginal macroducts absent from between L 1, each side with 1 duct between L 1 and L 2, 2 between L 2 and L 3, 2 on each of abd. V and IV, and 1 or 2 present between III and IV. Ventral microducts few, usually numbering no more than 20, scattered, occasionally concentrated near posterior spiracles.
Gland spines. Marginal gland spines on each side numbering 5 or 6 on abd. IV, and 1 on V; 1 present lateral to each pygidial lobe. Lateral gland spines on each side numbering 14–20 on abd. II, and 16–25 on III.
Perivulvar pores present in 5 groups, with 12–14 in anteromedian group, 24–30 in each anterolateral and 16–24 in each posterolateral group.
Host plant. Schima superba (Theaceae).
Remarks. Aulacaspis paralonganae sp. n. is similar to A. longanae in body form and L 1 shape, but can be distinguished by the following characteristics of the adult female (character states of A. longanae in brackets): (i) each side of abd. IV with marginal gland spines numbering 5 or 6 (3 or 4); (ii) lateral gland spines on each side numbering 14–20 on abd. II, 16–25 on III (4–11 on II, 6–10 on III); (iii) abd. VI with submedian dorsal macroducts on each side numbering 2 or 3, usually 2 (0–2, usually 1, never with 3); (iv) total dorsal macroducts numbering 28–46, usually 35–40 (21–35, usually 25–30); and (v) body 1190–1340 µm long, 680–780 µm wide (940–1090 µm long, 490–575 µm wide).
Etymology. The species epithet is derived from the Latin prefix ‘ para- ’, meaning resembling, and ‘ longanae ’, referring to A. longanae, meaning that the new species resembles A. longanae.
