Not my own photos, but I got permission by the observer to make the request here: La Gomera, Sept 2023

It's a Drosophila species: repleta species-group

I don't think so - the dark spots are too large, to manny bristles on the thorax and general shape says not a Drosophilid. Note also theremarkable eye stripe. I was going into the direction of a Cacoxenus species Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.

The arista is not long haired, so Cacoxenus might come in to mind, but it is not a species I know. Maybe an introduced species?

Cacoxenus perspicax is described to have a horizontal bar in the eyes

That fly can be a Phortica (subg. Sinophthalmus) sp. It is not P. (S.) picta which I know. Except of P. (S.) picta there is one more described P. (S.) species, one described subspecies and a number of not yet studied taxa. Distribution from SW USA to S. America. Also I do not exclude Cacoxenus (subg. Gitonides). If the specimen is available, I would like to study it, also I can arrange its DNA sequencing (most of its body can stay preserved if needed so).

unfortunately the fly hasn't been caught. I had excluded Phortica because the antennae do not seem to be plumose Edited by Carnifex on 23-09-2023 22:38 Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.

Really, the arista is rather bare or short pubescent... Maybe we should check the key to the Afrotropical genera?

Both P. (Sinophthalmus) and C. (Giitonides) have micropubescet arista. Still you are right with C. (Gitonides) - after consultation of literature I realized that some characters testify for its affiliation to C. (Gitonides) (lacking frontal keel, costa developed only up to r2+3). Maybe you are even right with C. (G.) perspicax, still unrecorded from Canary Islands, but note that there are more than ten species of C. (G.) in Africa - e. g. C.(G.) apidoxenus, described from Senegal...
