Remarks
- Systematics: Morrison (1928) assigned this genus to the Coelostomidiinae, characterizing it by: antenna greatly reduced to a plate-like appendage; legs reduced; without ventral cicatrices.
Vayssiere (1939) assigned this genus to Llaveiini of the Monophlebinae, while characterizing it by: body highly sclerotized; 9-segmented antenna; legs well-developed; seven pairs of abdominal spiracles.
In Hodgson & Hardy, 2013, the South American
Neocoelostoma and Nautococcus formed a clade sister to Monophlebidae, rather than forming a clade with the New Zealand members of Coelostomidiidae. To preserve the monophyly of Coelostomidiidae and Monophlebidae, Hodgson and Hardy suggested that these South American taxa could be treated as a separate family-level group, or Neocoelostoma could be transferred to Monophlebidae as was Nautococcus.
Foldi & Gullan (2014) recognized Nautococcus as a junior synomym of Mimosicerya although the described species are not the same, based on a review of the morphology of male and female instars. They transferred Mimosicerya to the Monophlebidae and noted that species of Mimosicerya do not secrete a test as do most Neotropical coelostomidiids. The preadult cuticle becomes heavily sclerotised and forms a protective cover for the adult female which can, therefore, be considered as "pupillarial" because it remains and oviposits within the exuviae of the previous instar.
Gavrilov-Zimin, 2018, resurrected the tribe Cryptokermesini within the family Margarodidae to place the genus Mimosicerya in relation to other genera that he felt belonged in a subfamily of Callipappinae (Cryptokermes, Mimosicerya, Paracoelostoma and Ultracoelostoma)
- Structure: Body broadly oval, female remaining within preadult exuviae after last moult. Derm membranous except for an approximately circular sclerotised area anteriorly bearing antennae, eyespots, multilocular pores, setae and numerous spines of varying stoutness and length. Ventral dermal pocket-like
depressions (apodemes) present, 2 per segment in a submedian line on abdomen (M. hempeli) or absent (M. mexicana, M. schraderae and M. williamsi). Antenna greatly reduced, platelike or bulbous, segments not discernable on slide-mounted specimens, but bearing a group of sensory setae. Mouthparts absent. Legs either absent (M. schraderae and M. mexicana), present but strongly reduced (M. hempeli) or represented by vestigial protuberances (M. williamsi). (Foldi & Gullan, 2014)
- Biology: All stages live either exposed, or hidden in cracks or under bark on twigs or stems of the host plant; the adult female is pupillarial, remaining inside the sclerotised preadult exuviae for reproduction. (Foldi & Gullan, 2014)
- General Remarks: Definition and characters by Vayssiere (1926, 1939 & 1948), Morrison (1928) and by Foldi (2009). Redescription and illustrations in Foldi & Gullan (2014).
