Remarks

• Systematics: The adult female of H. serrulata is similar to that of H. rapax in having a pyriform body, no perivulvar pores, antennae each with single seta, and ducts and glands analogous and distributed in a similar pattern; however, H. serrulata can be easily distinguished from H. rapax as follows (character-states for H. rapax in brackets): (i) plates simple (plates branched and/or fringed), (ii) posterior margin of median lobes entire (with obvious notch on outer margin), and (iii) absence of fringed plates between the median lobes (present). (Liu & Feng, 2018)
• Structure: Adult female: Scale cover subcircular, about 1.0 mm in diameter, dorsum with eminent transverse striae. Body pyriform, 990–1124 (1003) μm long. Eyes spur-like, each situated on ventral submargin of prothorax. Antennae each with 1 long seta and 1 short spine. (Liu & Feng, 2018) First-instar nymph: Body oval, contents yellow in life. Derm membranous except pygidium. Sparse microhairs scattered on mesothorax and metathorax dorsally and ventrally. Antenna filiform with 5 segments. Second-instar female nymph: Scale cover subcircular. Body oval with convex sides contents yellow in life. Antennae each 1-segmented, with single long seta and a microspine. Pygidium with 3 pairs of pygidial lobes, strongly sclerotized. Second-instar male nymph: Similar to second-instar female apart from: body elongate-oval with less convex sides. Abdomen obviously tapering posteriorly. A pair of large, robust ventral setae present submedially on abdominal segment IV. Adult male: Body slender. The adult male of H. serrulata is morphologically similar to that of H. cyanophylli, differing as follows (character states on H. cyanophylli): (i) terminal antennal segment with 4–9 fs (7–11 fs); (ii) posterior arms of postoccipital ridge bent at an angle of about 160° (140°); (iii) 4–6 hs scutal seta (8hs); (iv) metatarsi with 18–19 fs (11–15 fs), and (v) penial sheath with a pointed apex (a blunt apex). (Liu & Feng, 2018)
