- •
We compare the thorax morphology of flightless weevils based on 3D reconstructions.
- •
The thorax morphology is markedly influenced by aptery.
- •
The set of muscles is identical in the species examined, but differences exist in the size and shape of muscles.
- •
A fan-shaped muscle found in the two Trigonopterus species is interpreted as an adaption to the genus' defense strategy.
- •
The mesothoracic spiracle of Trigonopterus species is located externally on the metaventrite and not in the subelytral space.
