Anthocomus pristinus
Anthocomus pristinus is a of soft-bodied plant beetle in the Melyridae. It belongs to a of small, often brightly colored beetles commonly known as malachiid beetles or soft-winged flower beetles. The species is part of the Malachiinae, which is characterized by flexible and frequent association with flowers. Specific ecological details for A. pristinus remain poorly documented.

Identification
Members of Anthocomus are small beetles, usually 3–6 mm in length, with soft, flexible that do not fully cover the . Many in the exhibit metallic coloration, often green, blue, or coppery. Anthocomus pristinus specifically has not been described in sufficient detail in accessible literature to provide distinguishing features from ; identification to species level likely requires examination of male genitalia or other subtle morphological characters.
Habitat
in the Anthocomus are generally found in flower-rich including meadows, woodland edges, and gardens. They are often observed on umbelliferous flowers and other flowering plants where they feed on pollen. Specific habitat associations for A. pristinus are not documented.
Distribution
The distribution of Anthocomus pristinus is not well established in published sources. The Anthocomus has a Palearctic distribution with recorded across Europe and Asia.
Behavior
As with other members of Malachiinae, are likely and active on flowers. Some Anthocomus exhibit a defensive where they can retract their and appendages and feign death when disturbed.
Ecological Role
of related are known pollen feeders and may contribute to pollination. Their larvae are generally predatory on small insects and other arthropods in soil or leaf litter, though this has not been confirmed for A. pristinus specifically.

Taxonomic Note
Anthocomus pristinus is a valid name in Melyridae, but it appears to be rarely collected or reported. The absence of iNaturalist observations and lack of accessible species-level literature suggests it may be infrequently encountered, restricted in range, or potentially synonymized with another species pending revisionary work.
Data Deficiency
This record reflects significant gaps in available information. Most aspects of the , distribution, and identification of A. pristinus rely on inference from -level characteristics rather than -specific study.
