Abstract: GenusLecanodiaspisTargioni Tozzetti, 1869 Type species. Lecanodiaspis sardoa Targioni Tozzetti, 1869 by monotypy. Generic diagnosis. (adapted and modified from Hodgson 1973; Kosztarab and Kozár 1988; Williams and Watson 1990). Adult female test waxy or papery, enclosing adult and eggs. Adult female subcircular or elliptical. Antennae each normally 7–9 - segmented. Legs absent or each 1–5 - segmented, without tibio-tarsal sclerosis. Thoracic spiracles each associated with primarily quinquelocular pores that extend into spiracular furrow, terminating at enlarged spiracular setae on body margin; usually with two spiracular setae opposite each anterior spiracle; also with a single spiracular seta present opposite each posterior spiracle, except when posterior spiracular furrow divided, then end of each furrow with a single spiracular seta. Dorsum with cribriform plates normally present in two (rarely four) longitudinal rows. Anal ring bearing 8–10 setae and two or three rows of cone- or nipple-shaped pores; with an arched plate above anal ring. Anal plates each usually triangular, ridged and with two stout setae dorsally, plates normally connected at mid-line. Anal cleft short; anal lobes each with single long apical seta and associated short setae. Dorsum with various disc pores, 8 - shaped pores, tubular ducts and setae present. Ventral margin with a line of large 8 - shaped pores similar to dorsal pores, a submarginal line of smaller 8 - shaped pores, and a sparse band of minute bilocular pores reaching as far medially as an imaginary line formed by antennal bases, coxae and anal plates medially to the 8 - shaped pores. Minute simple pores and tubular ducts present throughout ventral surface; multilocular disc pores present around genital opening and more anteriorly; quinquelocular pores present in spiracular furrows, sometimes reduced to small groups near spiracles. Labium 1 - segmented, with short terminal setae.
