Genus Paralecanium Cockerell in Cockerell & Parrott, 1899

Type species: Lecanium frenchii Maskell, 1891b , by original designation.

Diagnosis. Dorsum with irregular quadrate patterns or radial lines from margin inwards; anal plates each with 3–5 short setae ( Figs 33E , 34F ); dorsal tubular ducts absent. Marginal setae fan-shaped, each with radial striations in outer area of seta ( Figs 32C , 33H , 34A ). Stigmatic clefts distinct and sclerotized ( Figs 33A , 34B ). Venter with multilocular disc-pores each with 10 loculi ( Figs 33I , 34H ); tubular ducts and microducts absent; and legs without tibio-tarsal articulatory scleroses ( Williams & Watson 1990; Hodgson 1994).

Remarks. Paralecanium consists of 29 described species, most of which are from the Oriental and Australian regions ( Hodgson 1994; García Morales et al. 2016). Adult females of the genus are easily recognized by the fanshaped marginal setae. Podoparalecanium shares this character with Paralecanium , but differs from it in having an asymmetrical body shape ( Hodgson 1994).
