Systematics: Sclerosococcus williamsi differs from the other four species in this genus by: 1) it lacks abdominal multilocular pores, 2) if the multilocular pores form a marginal band on both surfaces of the cephalothorax up to the metathoracic spiracles, then they are not arranged in groups (Granara de Willink et al. 2023).
Structure: Multilocular pores with 5–9 locules present in spiracular atrium. Multilocular pores absent or present on marginal and submarginal cephalothorax. Multilocular pores absent on dorsal and ventral abdomen. Numerous eight-shaped pore ducts of varying sizes on dorsum and venter. Marginal setae of the last four abdominal segments and of the anal lobe strong, with a bulbous base, inserted into a sclerotized depression. Body elongated oval or pyriform; length 1.62 (0.94–1.86) mm, width 0.66 (0.51–1.22) mm. Without legs. Dermis membranous, striated (easily seen at body margin); last abdominal segment sclerotized, segments V-VIII submarginally sclerotized. (Granara de Willink et al. 2023)
Biology: This species was found in flower calices. Apparently, it does not make pits. Each female forms a network of thin and long wax filaments that surround and protect it, leaving the posterior part of the body free. Without filaments, it shows little powdery wax and a yellowish color (Granara de Willink et al. 2023).
