Davide is right. Cryptocephalus fulvus and connexus have very similar male genitalia. In Poland I never collect such vittate form of C. fulvus, our dark aberrations are usually uniformly dark, without pattern (like female on my web page: http://www.colpolon.biol.uni.wroc.pl/cr ... fulvus.htm). Prof. Warchalowski suggested sevaral years ago that this vittate form of fulvus can be a different species but this hypothesis needs veryfication based on molecular studies.

Lech Hello!

It 's been a lot of time by our meeting here in Castelmarte and along the beautiful hills of Liguria, right?

The problem of C. fulvus vs. C. connexus are tormenting me for a long time, seemingly intermediate forms are very common and male genitalia are not very informative. Besides, C. fulvus is extremely variable in colour pattern in Italy! Sometimes I am tempted to think that maybe the two taxa are a single species in which C. connexus represents an extreme of the chromatic range. Andrzej is right, perhaps only molecular studies may resolve the issue.

Hello Davide,
I never forget our trips in Liguria and Castelmarte. We collected a lot of chrysomelids (Arima!!!, some mountain Cryptocephalus, Luperus alpinus etc.). In last years I spent many vacations in Mediterranean countries (Greece - both continental and islands, Turkey, Mallorca) and there are always fascinate days for me. I prefer Mediterranean climate and food and I feel in such countries much better than in cold Poland. I hope to back to Italy in future, especially I want to visit Sicily and Sardegna. In Summer usually is too dry and too hot for chrysomelids but I have found a new hobby - ants. My son is myrmecologist and I collect ants for him but some doublets preserve in my collection. They are also so beautiful insects.

I feel for all European entomologists Mediterranean region constitutes a fatal attraction! I can just attend it because of my work commitments: when my school closes the season is virtually over. But if you come next year in Italy it is possible that we can meet again. For me it would be a great joy.

As you probably know after the retirement of Carlo Leonardi, the current curator of the Museum of Milan is a specialist on ants: Fabrizio Rigato. This is a further good reason for coming again by us!

By the way, Lech, I have on hand a shocking datum of Tylocentra from Tunisia, a single specimen, unfortunately. Have you got any information about the occurrence of this subgenus in N. Africa?

Davide, I sent you detailed information about Tylocentra from Tunisia in e-mail, with some other data.
