( 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).

Aulacaspis paralonganae sp. n. , slide-mounted adult female. on Schima superba leaf. Scale bar = 100 µm. 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 .
