Plesiocis cribrum
Casey, 1898
Plesiocis cribrum is a small in the Ciidae (minute tree-fungus beetles), described by Casey in 1898. It is the sole member of its , which is distinguished from other ciid genera by specific morphological features of the and . The species has been documented in western Canada, with records from Alberta, British Columbia, and Manitoba. Like other Ciidae, it is presumed to be associated with fungal decay in wood, though specific ecological details remain poorly documented.

Identification
Distinguished from other Ciidae by the unique combination of features defining the Plesiocis: with a distinct reticulate (net-like) surface sculpturing, and with a three-segmented club. The specific epithet "cribrum" (Latin for sieve) refers to this punctate or reticulate elytral surface. Separation from the closely related genus Cis requires examination of antennal club segmentation and elytral punctation patterns.
Habitat
Associated with forested environments; specific microhabitat requirements are undocumented but inferred from -level patterns to involve dead wood and fungal substrates.
Distribution
Recorded from western Canada: Alberta, British Columbia, and Manitoba. GBIF records indicate presence in North America generally, with all specific locality records currently from Canadian provinces.
Ecological Role
Presumed to contribute to nutrient cycling through association with wood-decaying fungi, consistent with -level of Ciidae, though direct observations are lacking.

Taxonomic uniqueness
Plesiocis represents a , making P. cribrum the only available for comparison within its genus. This rarity may reflect genuine biological scarcity or limited sampling effort in appropriate .
Data deficiency
With only 4 iNaturalist observations and sparse literature records, most aspects of this ' remain undocumented. The was established based on distinctive rather than ecological data.
