Arthrolips fasciata
(Erichson, 1842)
Arthrolips fasciata is a minute in the , originally described by Erichson in 1842. Records indicate presence in Belgium with some uncertainty, and the species has been observed 18 times on iNaturalist. Like other members of this family, it is among the smallest beetles, typically associated with decaying matter and fungal . The Arthrolips is part of the diverse microbeetle fauna that remains understudied due to its diminutive size.

Identification
Distinguishing Arthrolips fasciata from requires examination of microscopic morphological features, particularly details of antennal structure, pronotal and elytral microsculpture, and male . The name "fasciata" may indicate a banded pattern useful for preliminary field recognition, but definitive identification relies on dissection and comparison with material. Separation from other European such as Corylophus or Orthoperus depends on subtle differences in body form and structure.

Appearance
Minute with body length likely under 2 mm based on characteristics. Members of typically have compact, oval to elongate-oval bodies with short bearing 3-segmented . The specific epithet "fasciata" suggests possible banded or striped coloration pattern, though this requires verification.
Habitat
Specific preferences for this are not documented. Members of generally inhabit decaying matter, , leaf litter, and similar microhabitats rich in decomposition. The Belgian records suggest temperate European woodland or anthropogenic environments where such microhabitats occur.
Distribution
Documented from Belgium with records indicating presence, absence, and doubtful status in different localities. The GBIF data suggest established occurrence in this region, though with some record uncertainty. No additional geographic range information is available from provided sources.
Ecological Role
As a member of , likely contributes to decomposition in microhabitats, though specific ecological functions for this are undocumented. Minute in this are generally considered part of the cryptic fauna associated with fungal and decaying matter .

Taxonomic stability
The has maintained consistent since original description, with no synonymy indicated in available sources. placement in (formerly sometimes treated as Corylophidae or included in broader concepts) is stable.
Data limitations
Despite being described in 1842, this remains poorly known in the literature, reflecting the general neglect of minute and . The 18 iNaturalist observations suggest recent increased through citizen science and improved microscopy access.
