Dienerella costulata
(Reitter, 1877)
Dienerella costulata is a small in the Latridiidae (plaster beetles or minute brown scavenger beetles), first described by Reitter in 1877. The Dienerella comprises minute beetles associated with mold and fungal growth. This species has been recorded from several Canadian provinces including Manitoba, Nova Scotia, Ontario, Prince Edward Island, and Quebec. Very few observations of this species exist in public databases.

Taxonomic Note
The Latridiidae (formerly part of ) contains minute beetles typically associated with mold, mildew, and fungal growth. The Dienerella is distinguished from related genera by specific characters of the and pronotum, though precise diagnostic features for D. costulata specifically are not readily available in general sources.
Data Limitations
This is poorly represented in public biodiversity databases. The GBIF match confirms accepted status but provides no additional biological data. The two iNaturalist observations offer no descriptive or ecological information. Primary taxonomic literature (Reitter 1877 and subsequent revisions) would be required for reliable morphological description and details.
