Megeleates sequoiarum
Casey, 1895
Megeleates sequoiarum is a small darkling beetle in the Tenebrionidae, first described by Casey in 1895. The is associated with coast redwood (Sequoia sempervirens) forests in California. It is rarely encountered, with fewer than ten observations documented on iNaturalist. As a member of the tribe Tenebrionini, it belongs to a diverse group of beetles adapted to arid and semi-arid conditions, though this species occupies the relatively moist environment of coastal coniferous forest.

Identification
Specific diagnostic features for distinguishing M. sequoiarum from and similar tenebrionids have not been documented in readily accessible sources. The Megeleates contains small to medium-sized darkling beetles with generally elongate-oval body forms and dull to moderately shiny . Accurate identification to level requires examination of genitalic characters and comparison with .

Habitat
Associated with coast redwood (Sequoia sempervirens) forest . The specific microhabitat preferences within these forests remain undocumented.
Distribution
Known from California, USA, specifically within the range of Sequoia sempervirens. The precise extent of its distribution within the redwood belt is poorly characterized due to limited collection records.
Host Associations

Taxonomic history
Described by Thomas L. Casey in 1895. The Megeleates was historically placed in subtribe Tenebrionina, though tribal assignments within Tenebrioninae have undergone revision. The specific epithet 'sequoiarum' directly references its association with Sequoia.
Data deficiency
This exemplifies the taxonomic impediment in North American Tenebrionidae: many described species remain poorly known ecologically due to limited collecting effort in specialized microhabitats and insufficient modern revisionary work.
