Mnesarchaeoidea is a superfamily of "New Zealand primitive moths" containing one family, Mnesarchaeidae and a single genus, Mnesarchaea, endemic to New Zealand.

Taxonomy and systematics
Mnesarchaeoidea constitutes the living sister taxon to the superfamily Hepialoidea.Within the family, there are two distinct genera, Mnesarchaea and Mnesarchella. The two are separated by differences in morphology and color. Mnesarchaea are white on the head and thorax scales while Mnesarchella have brown heads and thorax scales. There are currently 14 known species belonging to this family, four belonging to the Mnesarchaea genus and 10 to Mnesarchella.
Morphology and Identification
The mouthparts of the adult moths are functional, unlike Hepialoidea. About seven species are not yet described, and the group is under revision by Gibbs et al. (see also Gibbs, 1979; Dugdale, 1988). Their notable traits are their small wingspan of less than 12mm and their brown bodies. The family has numerous unique physical traits. The members of this family share certain traits with other members of the Lepidoptera order such as "discrete mandibles that lack articulation or musculature; a short, coiled, functional proboscis with intrinsic muscle fibres; a primitively 3-segmented maxillary palp; functional salivary glands (as in Lophocoronidae)."
Biology and behavior
The moths are mostly day-flying. The larvae live in silken galleries among liverworts and soil detritus. See Kristensen (1999: 57-59) for more details. They tend to be active from mid Spring to early Autumn in New Zealand (October to March). Throughout the day, they are most active during daylight hours, minus times when the sun is most intense. A noticeable difference between male and females is that males are the only ones that fly to travel. Females generally lay about 32 eggs in their lifetime. Larva of the family make silk-tunnels under foliage until they reach maturity, obtaining food from the tunnel.

History
Before the family was established, early collectors such as G.V. Hudson believed that individuals belonged to other families. An example is the Mnesarchaea fusiella, which originally was thought to be in the Tinea family. This error was later corrected in the 1900s.
