Remarks

• Systematics: Gavrilov-Zimin, 2018, resurrected the tribe Iceryini within the family Margarodidae to place the genus Crypticerya in relation to other genera that he felt belonged in a subfamily of Monophlebinae (Crypticerya , Echinicerya, Icerya and Steatococcus, which he considers a separate genus). He rejected the molecular evidence for the separation of Gigantococcus from Icerya in favor of a phylogenetic evaluation of reproductive strategies in different "traditionally accepted genera." Based on his morphological definition of the separation of genera, he considered Steatococcus a genus separate from Crypticerya. Therefore, he reassigned several species in Crypticerya to the genus Steatococcus, and described this new species in . ScaleNet is not following this change in classification and has assigned this species to the family Monophebidae. Gavrilov-Zimin & Stekolshikov, 2018 stated that this species differs from all the other African Iceryini, in the presence of numerous thick spiniform setae on the dorsum. Similar dorsal setae are known in some Neotropical Iceryini, but each of these Neotropical species has its specific features, for example, a characteristic combination of wax glands or cuticular tubercles, or lack of the marsupium.

  The genus Steatococcus is a junior synonym of Crypticerya, a Neotropical genus (Unruh & Gullan 2008). The correct generic placement of the African species “Steatococcus” hystrix therefore requires further research. It is close to Gigantococcus in possessing compound multilocular pores on the body margins and ventral submargins, 11 antennal segments, 3 pairs of abdominal spiracles, 3 circuli and a marsupium, and in lacking open-centre pores. It differs from all other African Iceryini in having numerous thick spiniform setae on the dorsum; in life, the body is evenly covered with soft, loose wax. (Watson, 2022)

• Structure: Female body broad-oval, 5–7 mm long, in life evenly covered with soft loose wax. Cuticle of medial zone of abdominal sternites in mature female invaginating and forming marsupium. Males unknown. Female ultimolarva differs from adult female in the 9-segmented antennae, absence of marsupium and marsupial band of multilocular pores.(Gavrilov-Zimin & Stekolshikov, 2018)
