Remarks

• Systematics: Pauroaspis chuanensis is similar to P. daedalea Gavrilov-Zimin, 2013 in possessing dorsal groups of 8-shaped pores and with the posterior abdomen sharply narrowed. However, it differs from P. daedalea by possessing the following features (condition of P. daedalea given in parentheses): (i) venter with dark-rimmed 8-shaped pores (without dark-rimmed 8-shaped pores on venter); (ii) ventral tubular ducts absent (minute tubular ducts present on venter, forming submarginal band); and (iii) minute 8-shaped pores present on dorsum (minute 8-shaped pores absent). (Li & Wu, 2025)
• Structure: In life: Body oval and purplish-red, enclosed in a thin and transparent test. Dorsal ridge absent; with dorsal filaments gathered in eight pairs of orange tufts, each tuft elongate and curving upward. Marginal filaments well developed, orange. Slide-mounted female: Body subcircular or oval, but posterior of abdomen sharply narrowed, 1.0–1.4 mm long and 0.9–1.0 mm wide. Antennae each with 1 segment, 12–13 μm long and 10–11 μm wide, bearing 2 sensory setae, each 12–15 μm long, and 2 short setae, each about 3 μm long. Labium with 1 segment, without setae. Eyes and legs absent. Spiracles numbering two pairs on venter of thorax, sclerotized, each spiracular opening containing 5 or 6 quinquelocular pores. Each spiracular furrow between spiracle and margin containing 28–30 quinquelocular pores irregularly arranged in 2 or 3 rows. A pair of dorsal tubes present near posterior end of abdomen, each tube 16–18 μm long and about 6 μm wide. Anal lobes absent. Anal apparatus about 20 μm long and 15 μm wide, with a sclerotized anal ring located at inner end of anal tube, ring without pores but probably bearing 2 setae (in all specimens, setae lost during preparation so anal ring only has 2 setal sockets visible). Apical setae degenerate, each only 4–5 μm long. (Li & Wu, 2025)
• Biology: Sometimes associated with sooty mold growths (Li & Wu, 2025).
