Remarks

• Systematics: The absence of a long seta on the trochanter is very unusual on species with fully-developed legs, otherwise only known on P. elongatum within the genus Paralecanium. Adult female P. hainanense are also characterised by: (i) venter seemingly always asymmetrical; (ii) short, curved, setose dorsal setae; (iii) large dorsal pores in broad submedial bands; (iv) few (0–2) multilocular disc-pores in abdominal segment V; (v) generally rather club-shaped stigmatic spines; (vi) marginal ornamentation in the form of small thorn-like sclerotised triangles, and (vii) each anal plate with a small seta situated centrally. Paralecanium hainanense is very similar to P. neomaritimum; the differences are discussed under the latter species. Other Paralecaniumspecies that have somewhat similar adult females are: P. elongatum, P. machili and P. marginatum.
• Structure: Slide-mounted adult female. Body basically oval and rounded at both ends but showing strong asymmetry, particularly ventrally. Length 2.1–2.6 [1.75–2.13] mm, width 1.6–2.0 [1.5–1.85] mm. (Hodgson & Williams, 2018)
