Lecanium expansum Green, 1896: 9.
Diagnosis.Dorsum with setae bluntly spinose or slightly capitate ( Fig. 33D); preopercular pores present anterolaterally to anal plates, in 2 groups on each side ( Figs 32E, 33G). Stigmatic clefts each containing 3–9 stigmatic spines ( Fig. 33A). Legs represented by leg stubs ( Figs 32D, 33J) (partially adopted from Green 1904b; Morrison 1920; Tao et al. 1983; Hodgson & Williams, 2018).
Material examined.30 ♀♀, LAOS, Phou Khao Khuay National Bio-Diversity Conservation Area, Thaphabath Dist., Bolikhamsai Prov., 4.v.2015, coll. J.Y. Choi, on Mangifera indicaL. ( Anacardiaceae).
Hosts.Polyphagous. According to García Morales et al. (2016), P. expansumhas been recorded from plants belonging to 10 genera in 9 families.
Distribution.Mainly known from Australian and OrientalRegions ( Hong Kong, India, Indonesia, Malaysia, Singapore, SriLankaand Taiwan)( García Morales et al. 2016); Laos(new country record). FIGURE 32. Paralecanium expansum(Green, 1896). A, population of females in life; B, slide-mounted adult female; C, marginal setae; D, leg stub near antenna; E, groups of preopercular pores. Scale lines for B = 0.5 mm; C, E = 50 µm; D = 10 µm. Economic importance. Paralecanium expansumhas not been recorded as an economically important pest.
Remarks. Paralecanium expansumclosely resembles P. quadratum( Green, 1904b), but has 2 groups of preopercular pores on each side and leg stubs, whereas P. quadratumhas 3 groups of preopercular pores on each side and entirely lacks legs ( Tao et al. 1983).
