Remarks

• Systematics: The adult females of P. peradeniyense are extremely similar to P. maritimum (both species share arrow-head-shaped sclerotisations as marginal ornamentation) but differ as follows (character-states for P. maritimum in brackets): (i) anal plates together almost as broad as long, ratio of length to combined widths 1:0.77 (clearly much longer than broad, ratio of length to combined widths 1:0.55); (ii) anal plates each with a convex outer margin (without a slight bulge on anterior margin); (iii) each anal plate with a seta about half-way along inner margin (absent); (iv) dorsal large pores much larger, each 8–10 μm wide (smaller, each 5–7 μm wide); (v) dorsal setae sparse but widespread in radial lines from margins (very scarce); (vi) radial lines from margins clear (obscure, only indicated by distribution of dorsal pores and setae), and (vii) marginal ornamentation in the form of sclerotised triangles with deep “stalks”, each stalk as deep or deeper than marginal setal sockets (similar but with very short “stalks”). Paralecanium peradeniyense is also similar to P. cypripedium and P. leei. See under these species for comparisons. (Hodgson & Williams, 2018)
• Structure: Marginal setae transversely ovoid. (Martin & Lau, 2011) Unmounted material. “Adult female deep reddish brown; ovate, narrow in front, evenly rounded at each extremity; very slightly convex above; with a broad median cavity below the abdomen forming a shelter for the newly hatched larvae. A very distinct longitudinal ridge, on each side of which are three longitudinal series of impressed polygonal spaces with concentric markings. Marginal area with many short transverse carinae. Surface, except in polygonal spaces, minutely and closely punctate.” “Length 3.50 to 4.0 mm. Breadth 2.5 to 3.0 mm.” (Green, 1903, p. 241 in Hodgson & Williams, 2018). Slide-mounted adult female. Body rounded at both ends, broadest across abdomen. Length 3.0–4.0 mm, width 2.1–3.0 mm. (Hodgson & Williams, 2018)
