Remarks
- Systematics: The adult female of P. ejinensis is closest to that of P. embiensis Jashenko, 1994. Adult female P. ejinensis differ from those of P. embiensis by having (contrasting character states in P. embiensis in parentheses): (i) antennal segment III naked (with 1 long hair-like seta); (ii) thoracic spiracles each with a group of 4–6 spiracular disc-pores (each with 2–4 spiracular disc-pores); (iii) long hair-like setae each shorter than 400 µm (up to 450 µm long); and (iv) host plant belonging to Fabaceae (Poaceae) (Zheng & Wu, 2024).
- Structure: In life: Body egg-shaped, violet-red, covered by abundant hair-like setae; legs well developed, foreleg fossorial. Slide-mounted material: Body ovoid, 5.0–6.9 mm long and 3.7–5.0 mm wide; derm membranous. Antennae 9 segmented. Apical segment with apex rounded, 2.4–3.2 times as long as segment II; with 4–10 flagellate setae, 9–17 sensory setae, and a group of 5–9 sensory organs. Sensillum placodeum on segment IV elongate, containing 4–7 sensilla. Eyespots each 43–53 µm wide, slightly convex, enclosed asymmetrically by a smooth sclerotized plate. Mouthparts absent or vestigial, derm usually folded at appropriate location. Thoracic spiracles well developed. Abdominal spiracles simple (Zheng & Wu, 2024).
- Biology: Porphyrophora ejinensis is univoltine in Nei Monggol Autonomous Region; despite long-term rearing, no adult males were found so it is deduced that the species reproduces parthenogenetically (Zheng & Wu, 2024).
- Economic Importance: No clear evidence of any feeding damage caused by P. ejinensis was found (Zheng & Wu, 2024).
- General Remarks: See Zheng & Wu (2024) for description and illustration of nymph and adult female.
