Remarks

• Systematics: Paralecanium maritimum belongs to a group of species that has radial sclerotised dashes as marginal ornamentation. The adult females can be distinguished from those of the other species by the possession of the following character-states: (i) fine, rather setose dorsal setae; (ii) large dorsal pores each about 4–6 μm wide, common in a broad submedial band; (iii) rather elongate anal plates; and (iv) marginal ornamentation in the form of 2 or 3 spear-head-shaped markings between marginal setae. Adult female P. maritimum are perhaps most similar to those of P. planum but the latter has much larger marginal sclerotisations, with 7 or 8 between marginal setae, and much smaller dorsal pores. (Hodgson & Williams, 2018)
• Structure: Unmounted material. ‘Scale protected by a secretion that becomes tough and gelatinous under treatment with potash.’ ‘Differs from type [Lecanium planum] in smaller size and absence of dermal cells’ ‘Found on both surfaces of leaves of a thorny shrub growing on the sea-shore (within reach of the surf).’ (Green 1896, p. 9 in Hodgson & Williams, 2018). Slide-mounted adult female. Body broadest across abdomen. Length 2.2–2.6 mm, width 1.7–2.0 mm; many showing some asymmetry. ( Hodgson & Williams, 2018)
