They were very very common along the shores of the river Tomebamba in Cuenca, Andes of Ecuador. But they're very wary and difficult to approach, flying easily when disturbed. They always land in low plants, almost never in stones or soil. The river is contaminated and full of garbage. The surroundings are a lawn of grass with scattered trees and then the city. Size of the fly was similar to a housefly. Photographed on 5th October.

Anthomyiidae or possibly Muscidae.

Anthomyia. Compare Anthomyia albostriata (van der Wulp, 1883), original description below.

Chortophila albostriata n. sp.

Nigra; thorace striis duabus dorsalibus subparallelis albis; pleuris stria aequali; abdomine maculis duabus albis in singulis segmentis; alis subhyalinis. — ♂ long. 4, 5 mm.

Kop met sprieten en palpen zwart; aangezigt met witten weerschijn; voorhoofdsdriehoek fluweelzwart; de oogen van boven naauwelijks iets gescheiden. Thorax fluweelzwart, op den rug met twee breede witte langsbanden, die van voren een klein weinig tot elkander neigen en van achteren over het eveneens fluweelzwarte schildje zijn voortgezet; een dergelijke witte band ter wederzijde van de schouders naar den vleugelwortel; achterrug grijs. Achterlijf plat, bandvormig, naar achteren iets versmald, zwart; op den tweeden en elk der volgende ringen twee groote witachtige vlekken, die alleen in sommige rigtingen duidelijk uitkomen en eene rugstreep en de insnijdingen vrijlaten; het achterlijf digt met fijne borstels bezet; onder den voorlaatsten buikring een paar groote schubvormige aanhangsels. Pooten zwart; de dijen met witten weerschijn. Vleugelschubben witachtig. Vleugels glasachtig met flaauwe bruinachtige tint en een duidelijk randdoorntje; middeldwarsader op twee derden der schijfcel; cubitaal-ader en discoidaal-ader evenwijdig; schijfdwarsader naauwelijks iets gebogen, op een derde gedeelte der eerste achtercel ingewricht.
Een ♂ uit Argentina (Weyenbergh).
De soort is digt verwant aan Anthomyia Lindigii Schin. (Dipt. Nov. Reise, 298. 12), die zich echter onderscheidt door de naar voren uit elkander loopende thorax-strepen en den zwartbruinen zoom aan den voorrand der vleugels; de vorm van den kop en het achterlijf is volkomen zooals Schiner dit van zijne soort aangeeft; hij maakt evenwel geen melding van aanhangsels aan den buik bij het ♂.

Many thanks John, it seems to match well with the description. It seems to be missing any image of the species in Google. I also can't find info about if the species is found in the Neotropics, it is? There should be more online info for a species that is very common in numbers in a populated and modern city such as Cuenca.

It is a South American species ("Een ♂ uit Argentina"). I do not know of any key to species or review of South American Anthomyia. When Pont compiled the catalog of tropical American Anthomyiidae in 1974 he wrote "There is no modern revisionary work on Neotropical Anthomyiidae, either at the generic or the specific level".

There are several South American Anthomyia with three dark stripes on the thorax. I do not have all the descriptions. Stein did not distinguish his 1911 species from van der Wulp's albostriata. His virgata and albilamellata are probably not your flies, the first being truly holoptic and the second having more brownish stripes, but they are similarly marked. I do not have Albuquerque's 1959 paper.

See https://doi.org/1...60/15.1.93 for some of the variety of Brazilian Anthomyiidae. There is a tendency to spotted wings in Anthomyia.

I can no longer send private messages (and maybe not receive?), even though my inbox and outbox are not yet full. I write, click "send" and they disappear and never show up in the outbox.
