Yes, definitely Dasyrhamphis, male above and female below. There are 2 species with strongly hooked antennae - D ater and D anthracinus. The dusted subcallus (area just above the antenna) suggests anthracinus. Typically, the wings should also have a central clear area compared to ater which shows well in the field, though I think there is a lot of variation in this character. I collected a series of both sexes in Sardinia last month which I believe are all anthracinus
