Here's a real giant among the African Cerambycidae - Tithoes (fmr. Acanthophorus) maculatus, which can reach at least 95 mm -

This species is widespread across equatorial Africa. Like the monotypic Titanus giganteus of the South American tropics, Tithoes is also in the subfamily Prioninae, but belongs to a different tribe (Acanthophorini).

Looks scary! I wouldn't let my fingers get near those mandibles (male or female).

The first pictures shows Tithoes confinis (Lapoerte de Castelnau, 1840), male.
The pair on the second one should be T. maculatus (Fabricius, 1792) as the site says.
Third photo is most likely confinis again.

These two species are often sympatric, are quite similar to each other, and the markings can vary considerably between individuals. Now, I'm wondering if the Tithoes specimens in my collection (labeled as maculatus), might actually be confinis.

what are the localities of these Tithoes ?
yes Pierre is right, 1 and 3 are confinis, but 2 can be frontalis or maculatus (two close sp, locality may be important as photos are not always sufficient)
