Diamesus is a genus of rather large carrion beetle with two species distributed in tropical Asia and Australia. Like other Silphinae, it has an antenna with 11 segments. About 3 or 4 abdominal segments are visible beyond the tip of the elytra. The elytra themselves have longitudinal keels. The type species is Diamesus osculans. The larvae are broad and flat and somewhat cockroach-like (blattiform).

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Diamesus osculans has left across the world's sequence archives.

09Environmental DNA16 detections
Where the DNA of Diamesus osculans was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
