Tanzania. 9 mm.
I suspect this to belong to Hyagnis. It seems there is only one species in Tanzania - Hyagnis brevipes Breuning, 1939.
Can anyone help with it? |

Yes, Hyagnis, that's for sure! However, I hesitate..... between breviceps and strandiellus....... The type of strandiellus is logically found in the collection of the Smithonian Institute which is given disappeared however I think the type (in litteris) of Hyagnis congoanus is the Type of strandiellus ! Breuning often did, he gave a name to an individual but when he made his description he changed the name (these cases of figures are not rare in Breuning!) I think your insect is strandiellus because he too has a third article longer than the fourth ? The typus of breviceps is Dresden Muséum .
I think it would be nice to compare your insect with the two named ones (breviceps and "congoanus" = strandiellus) and then you will tell us (ask for the Dresden type picture, and I will scan the congoanus = strandiellus in litteris type picture for you.
Breuning's descriptions are too brief
And keep us informed of your search, I'll scan this we what I have... (I hope it will work...)

Dear Jérôme. Thank you for interesting reading. Always like a detective story with Breuning's descriptions.
However, this time the situation seems to be a bit simpler. The beetle has very short gena, shorter than an eye by the factor of two... at least. According to the Beruning's Revision des Apomecynini... 1960, this character separates immediately the group of three species: strandiellus, vagemaculatus and stramentosus. The apex of elytron is very obliquely truncated from the inner side, forming a sharply triangular tip. This feature fits only H. strandiellus. The description of the species, in particular the absence of white spots and the availability of black premedian spot fits as well.
I'll try to acquire also a photo of H. breviceps HT to complete the story.
At the moment, I think Hyagnis strandiellus Breuning, 1942 is a correct name. |

| So if the Dresden Museum sends you a picture of the H breviceps type it would interest me for my file? Thank by advance. |
