Psiloscelis abnormalis
Mann, 1924
clown beetle
Psiloscelis abnormalis is a of clown beetle in the Histeridae, described by Mann in 1924. It is known from limited distribution records in the northern Great Plains region of North America, specifically from the Canadian provinces of Manitoba and Saskatchewan and the U.S. state of North Dakota. Like other members of Histeridae, it is presumed to be associated with decomposing organic matter, though specific ecological details remain undocumented.

Identification
Can be distinguished from other Psiloscelis by the specific combination of morphological features described in the original 1924 description by Mann. Within the Psiloscelis, identification to species level requires examination of detailed structural characters including genitalia and elytral striation patterns. Separation from other histerid genera is based on the characteristic body form and antennal club structure typical of Psiloscelis.
Habitat
Records indicate presence in prairie regions of the northern Great Plains. Specific microhabitat preferences have not been documented, though histerid beetles in this are generally found in association with soil and decomposing matter.
Distribution
Known from Canada (Manitoba, Saskatchewan) and the United States (North Dakota). Distribution appears restricted to the northern Great Plains region of North America.
Ecological Role
Presumed to function as a scavenger in decomposition systems, based on -level characteristics of Histeridae, though specific ecological role has not been documented for this .

Taxonomic note
The specific epithet 'abnormalis' refers to distinctive morphological features that deviated from typical Psiloscelis form as noted in the original description. The remains poorly known with no published ecological studies and zero observations in iNaturalist as of current records.
Data gaps
