Makes me think of some Monochamus;
Cameroon, 24 mm.

No, it isn't: the antennnal scape is missing the apical cicatrix typical of this tribe; moreover, it has an unusual white line above.
It should be Baraeus taeniolatus (Chevrolat, 1857), belonging to the tribe Pteropliini.
I have found a picture of the apparently same species here, just coming from Cameroon.
The genus includes some other African species, among which vittatus Aurivillius (original picture attached). |

Yes, this fits very well. The bright line on the frons ant the scape of antennae is very particular and strikes immediately when you see this beetle first. The photo on Owen's beetles page is too bright, the original colour of the beetle's body is dark chocolate brown.
Thank you, Francesco! |

By coming back to this species, it is interesting to observe that N. taeniolatus has never been recorded from Cameroon, from where Breuning (1955) described B. subvittatus.
The original description of Temnoscelis taeniolatus can be read here (79-81), while the description of subvittatus follows:
Proche de vittatus Auriv., mais l'épine latérale du pronotum pointue et plus courte et la coloration élytrale différente.
Élytres couverts de pubescence brun jaunâtre, Chaque élytre orné d'une grande tache médio-latérale brune foncé qui s'étend presque jusqu'à la suture et d'une très petite tache subarrondie subsuturale brune foncé (sans taches ni au quart basilaire ni au quart apical).
Cameroun, Bitje River (Coll. Oberthür).
Hence, these three species are characterised by a scape with a yellow line... nevertheless, N. taeniolatus (p. 80) has a lateral whitish spot (petite taché cendrée) in the black lateral pattern missing (?) in this specimen.
Consequently, I think that it may be better identified as B. subvittatus Breuning, 1955. |

Camerun: Baraeus subvittatus?
