  In the Oriental Region, N. fanjingensis is similar to N. koeroesicsomai and N. vasarhelyii in having 7-segmented antennae. It differs from N. koeroesicsomai in having (character states in N. koeroesicsomai in parentheses): (i) antennal apical segment with subapical and medial sensory setae (without subapical and medial sensory setae); (ii) ovisac band with lateral sections incomplete (ovisac band complete); (iii) dorsal marginal clusters of abdominal segments III‒V or IV‒V fused to form a continuous series (dorsal abdominal marginal clusters all separate); and (iv) dorsum with quadrilocular pore rows between wax plates (only small number of quadrilocular pores between wax plates). N. fanjingensis differs from N. vasarhelyii in having (character states in N. vasarhelyii in parentheses): (i) quadrilocular pore rows present between dorsal wax plates (quadrilocular pores absent from between wax plates); and (ii) dorsally, marginal clusters on abdominal segments III‒V or IV‒V fuse to form a continuous section (clusters of abdominal segments II‒V fuse to form a continuous series). (Zheng & Xing, 2021)The two previously documented adult males of species of Ortheziidae (N. americana and N. floccosa) both have nine-segmented antennae (Morrison 1925; Koteja 1986; Vea 2014); however, in Newsteadia fanjingensis. there are 10 antennal segments. Other antennal features of N. fanjingensis are similar to the known males of Newsteadia, including the absence of simple pores on the scape. Newsteadia fanjingensis also is different in having developed hamulohalteres with a hamulus present and the forewing with an anal lobe and fold, whereas in the other Newsteadia males, hamulohalteres are absent and the forewing anal lobe is not developed. This may prove the point that the purpose of the fold in the anal lobe is to hold the hamulus. Like N. floccosa and N. americana, N. fanjingensis has pores and setae on the posterior sternites, but the new species differs from the other two adult males in that the sternites on abdominal segments II–VI each tend to be separated into anterior and posterior parts in N. fanjingensis (these sternites are intact in N. americana and N. floccosa). In the two previously documented Newsteadia males, there are three setal groups on the genital segment, but N. fanjingensis has only two groups, possibly because the anterior two groups have merged into a single group.

• Structure: Adult female body with wax plates subrectangular. Dorsum entirely covered with white wax plates; those on middorsum protrude forwards, and plates on margin radiate in all directions. Venter of abdomen covered by waxy ovisac. Exposed body (with wax plates removed) oval. Body yellow, eyestalk black at base, yellow at tip. Many spines present on dorsum. Slide-mounted female body 1.8 (1.6–2.2) mm long, 1.4 (1.2–1.9) mm wide. Antenna 7 segmented apical segment longest, scape widest, segments III–VI rather short and subequal. (Zheng & Xing, 2021) Live adult male slender; wings oval; legs slender and well developed; antenna and wings longer than body; compound eyes black; body greyish white because mealy and cottony wax products more-or-less cover the body; with wax filaments protruding from the tubular pores on abdominal segment VII. Adult male, soaked in 75% ethyl alcohol, with pleural region and wings nearly transparent, and antenna, extremities, sclerites on head, thorax and abdomen brown. Head clearly separated from thorax. Slide-mounted adult male body length 1.8–2.1 mm, thorax about 0.5–0.6 mm wide. Body with few hair-like setae (hs); loculate pores absent. Simple minute pores (smp) present throughout body, each 2–3 μm in diameter. (Zheng & Xing, 2021)
• Biology: The specimens were collected from under the mosses Platyhypnidium riparioides (Hedw.) Dixon (Bryophyta: Brachytheciaceae) and Metacalypogeia sp. (Marchantiophyta; Calypogeiaceae), growing on the trunks of Acer sp. (Magnoliophyta; Sapindaceae).
