Lichenomima sparsa
Lichenomima sparsa is a of barklouse in the Myopsocidae. The 'cf.' designation indicates a specimen resembling but not definitively identified as this species. Members of this are typically associated with lichen-covered substrates. The species is part of a group of that feed on microflora growing on bark and rock surfaces.

Identification
Distinguished from other Myopsocidae by the pattern of wing setation and venation details, particularly the shape of the areola postica. Separation from requires examination of genitalic structures; L. sparsa specifically has distinctive male paramere and female subgenital plate shapes. The 'cf.' designation indicates uncertainty in identification to level.
Appearance
Small, soft-bodied insect with broad, hairy wings held roof-like over the body. long and . Body and wings covered with setae. Wing venation includes a nodus and pterostigma; forewing with areola postica. Coloration generally mottled or speckled, providing camouflage against lichen substrates. Body length approximately 3-5 mm.
Habitat
Found on tree trunks and branches, particularly those covered with crustose and foliose lichens. Also occurs on rock outcrops with lichen growth. Requires humid microhabitats that support lichen .
Distribution
Published records indicate presence in North America, with documented occurrences in the western United States. Exact range boundaries remain poorly defined due to taxonomic uncertainty and limited collecting effort.
Diet
Feeds on lichen tissues, algal , fungal , and detritus trapped within lichen thalli.
Behavior
Active during daylight hours. Runs quickly over substrate when disturbed. Weak capability used primarily for short between nearby substrates. sometimes observed on favorable lichen patches.
Ecological Role
Contributes to nutrient cycling in lichen through grazing activity. Serves as prey for small spiders and other in forest and rock outcrop .
Human Relevance
No direct economic significance. Occasionally encountered by lichenologists and entomologists conducting biodiversity surveys. Presence may indicate healthy, undisturbed lichen .

Taxonomic Uncertainty
The 'cf.' (confer) designation indicates that the specimen resembles L. sparsa but definitive identification was not made, typically due to lack of examination of critical characters or absence of mature specimens. This notation is common in ecological studies where destructive sampling for genitalic dissection is undesirable.
