Identification
Identification to level requires examination of microscopic characters. Phalacridae are generally small (2–4 mm), oval, convex beetles with smooth, often . Members of Xanthocomus may be distinguished from related by antennal structure and details of the pronotal and elytral , though specific diagnostic features for X. rutilans have not been summarized in accessible literature.
Distribution
Observations documented on iNaturalist are extremely sparse (5 records), suggesting a limited known range or low detection rate. No published distribution summary is available.

Data scarcity
The iNaturalist platform records only 5 observations of this , and no Wikipedia summary exists. This level of documentation suggests that X. rutilans is among the many species that lack focused study, despite being described in the taxonomic literature. The Phalacridae as a whole is associated with fungi and decaying plant matter, but species-level remains largely undocumented.
