I think it is a Ptycholaemus.
One of the African specialists should be able to identify it to species. |

| Maybe Striatoptycholaemus variecollis (Schwarzer, 1931) |

Fuzzy topic, already discussed here.
Now, basing on Adlbauer's writings which are so far the only complete study we have, I see 2 possibilities (the problem is that the photo does not clearly show the surface of the pronotum).
- Either Ptycholaemus troberti Chevrolat, 1858, but usually this species has bright silvery vittae. Here they appear yellowish golden but this could be due to the photo, or some grease to remove.
- Or we have Striatoptycholaemus variecollis Schwarzer, 1931, the large and flattened antennal joints fit well with this item. |

Thanks everone for there help.
I have looked closely at your link Pierre and as far as I can tell it is nearest to Striatoptycholaemus variecollis Schwarzer, 1931, but with some differences, apart from slight difference in pronotum, mine has much shorter antenna and is from Tanzania not Cameroon.
I can confirm that my images are pretty accurate in colour and I would rule out Ptycholaemus troberti Chevrolat, 1858, I cannot find any images of Derolus gabunensis so have no way of comparing them.
I have attached a close up of pronotum, still not very clear but best I could do

This species does not correspond to none of the already described ones.
It is about a Derolus (= Ptycholaemus, Striatoptycholaemus, see here) of arid habitats, still to be described. This might explain the short antennae.
I move the topic into the secret section.
Ps. Derolus gabunensis is the first species of this topic. |

I have just bought the same species coming from Tanzania, Morogoro, but I cannot identify the exact locality: Nguu Mts.?
Where are coming your specomens from, Len? |

| If it is Morogoro, then it might be Uluguru mts. I have many insects from that area. |
