01Narrative

Anoplolepis steingroeveri is a species of ant. It is commonly known as the black pugnacious ant. It is native to southern Africa, and occurs in South Africa, Lesotho, Botswana and Namibia. The worker is similar in appearance to darker morphs of the common pugnacious ant (Anoplolepis custodiens), but that species has a chequer-board-like dark pattern on the gaster, which is caused by reflection of light by pubescent hairs which lie in different directions on the two sides.

05DNA & barcoding15 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 Anoplolepis steingroeveri 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.

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.
