Remarks
- Systematics: Subfamily: Myzolecaniinae. Tribe: Myzolecaniini.
Gullan et al. (1993) suggested that Cryptostigma could become a junior synonym of the much older name Myzolecanium, but that a systematic revision of the group would be necessary before making such a decision. Hodgson (1994) also considered Cryptostigma to be close to Myzolecanium, based on comparison of the type species of each genus. (Kondo, 2010b)
- Structure: The genus Cryptostigma is currently included in the subfamily Myzolecaniinae, a group erected by Hodgson (1994a) to include species with the following combination of features: lack of (i) dorsal tubular ducts and (ii) eyespots; and the presence of: (iii) anal plates with numerous setae on dorsal surface, (iv) particularly large spiracles, with broad bands of spiracular disc-pores between margin and spiracles, (v) ventral tubular ducts of only one type, frequently restricted to a group on each side of genital opening, (vi) bands of (often rather spinose) setae replacing the normal pairs of long pregenital setae, (vii) reduced legs with claw digitules, (viii) reduced antennae, and (ix) a short anal tube. (Kondo, 2010b)
- Biology: Most members of the genus Cryptostigma are found internally on their host plants in hollow branches, or trunks in association with ants. (Kondo, 2010b)
- General Remarks: Definition and characters given by Williams & Watson (1994) and by Hodgson (1994a).
