Il capo sembra più da Clambidae, ma quelle elitre così corte!!

A Cybocephalus (Nitidulidae, or a family on its own, according to opinions) ? Are tarsi 4-4-4 articles as they seem by the photo?

Regards G.

Clambidae – it´s not Clambus, Loricaster, Calyptomerus. I dont know another genus in west Palearct.

Cybocephalus, Nitidulidae - I sent this photo to Mr Jelinek in Prague. He does not know what it is. I ´ll tarsi calculate, but I have not this beetle at home now.

Leiodiidae ?!?!

Molti caretteri corrispondono.
Gli occhi penso siano più arrotondati di quello che sembrano.
Anche le elitre penso siano meno corte di quanto appaiono, tanto da ricoprire maggiormente l'ultimo articolo addominale. Più di quanto appare dalla foto.
Solo con le dimensioni (1,9 mm.) siamo un poco oltre la media.

Forse una foto laterale ed una ventrale possono aiutare.

Ciao

I sent the photo to our great coleopterist Adam Slipinski and he has the same opinion like Giuseppe: probably Cybocephalidae (or Clambidae) but photo of ventral part of body is necessary to proper identification.

By Jon Cotter it is not Leiodidae and Clambidae, but Cybocephalidae or Nitidulidae.

Eyes are not round rather flat.

I think it's not Clambidae. This beetle is very hard, has strong burrowing legs with hairs.

I think it could be a Cybocephalidae but in Catalogue of Palearctic Coleoptera this genus is not. Cybocephalidae have not a hair on the legs.

I'll try to make better pictures with more details.

Here is the answer of Trevor R. Smith specialist from the U.S.

That is a very nice specimen and beautifully mounted. You are correct this beetle is in the family Clambidae. Unfortunately, that is about as much as I can say. I am unfamiliar with the European and Mediterranean clambids. In the U.S., we only have three genera in this family with the dominate genus being Clambus.
Thanks for sharing the picture and please keep me in mind if you come across any cybocephalids in your travels.

Clambidae or Cybocephalidae ?!?!?!

Hello Marion,

At this point, a photo of ventral side will probably answer your question,
Regards
G.

Propongo l'accorpamento in un'unica famiglia.



Sicuramente una verifica della parte inferiore è importante ma, altrettanto discriminanti, sono i sotto elencati caratteri, apprezzabili anche in foto.
Clambidae: antenne di 8-9-10 articoli; clava antennale di 2 articoli; elitre pubescenti.
Cybocephalidae: antenne di 11 articoli; clava antennale di 3 articoli; elitre glabre.

Quindi Cybocephalidae (sono predatori di Diaspidi).

Ciao a tutti
Giuseppe

Beetle is black with bronze luster. Head, pronotum and elytra matt with fine punctation end of elytra with wrinkles. Lateral margin of elytra behind the shoulders with a small protuberance. According to the hind thighs and aedeagus it's not Clambidae. It is Cybocephalidae?

With great probability it is Cybocephalus metallicus Baudi, 1870. With Dr. Rafal Ruta we compared it with description in the revision of Palaearctic Cybocephalidae by Endrödy-Younga and in all characters (especially setose legs, shape of head and genitalia) the specimen from Crete agree with C. metallicus. It is distributed on Mediterranean islands and was recorded also from Crete.
