Megacephala regalis angulicollis (Kolbe, 1892)

A “subspecies” that became a lesson in how extreme colour and shape variation can manufacture false species.

About this species

Information reviewed15 July 2026

The gallery name represents the historical form angulicollis. Modern checklists generally absorb it into the highly variable African tiger beetle Megacephala regalis rather than maintain it as a separate valid subspecies.

What makes this species remarkable?

Megacephala regalis accumulated an extraordinary trail of named forms — angulicollis among them — as collectors repeatedly mistook regional variation in colour, sculpture and body shape for separate taxa.

Field notes record the angulicollis form running on fallow ground at night, matching the genus’s transformation from a daylight “tiger” into a heavy-headed nocturnal pursuit predator.

The head is proportionally enormous and packed with jaw-closing muscle; its mandibles are not decorative horns but functional blades able to subdue prey much larger than that taken by ordinary small tiger beetles.
