01Narrative

Trachelyopterus insignis is a species of catfish from the freshwater driftwood catfish family, Auchenipteridae. It is commonly found in rivers of northern South America, where it is called the chivo (lit. "goat"), the rengue, or the doncella (lit. "maiden").Ferraris, C.J. Jr., 2003. Auchenipteridae (Driftwood catfishes). p. 470-482. In R.E. Reis, S.O. Kullander and C.J. Ferraris, Jr. (eds.) Checklist of the Freshwater Fishes of South and Central America.

05DNA & barcoding33 specimens

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 Trachelyopterus insignis has left across the world's sequence archives.

Variant network

Each circle is a barcode variant; bigger = more specimens, colour = region. Lines join the most similar variants and the tick marks count the mutations between them — a tight cluster is one “dialect”, a long line a more divergent lineage. Click a circle to list its actual specimens.

09Environmental DNA25 detections

Where the DNA of Trachelyopterus insignis 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.
