Antho help please!

Hi all,

I've been shy of working with Athomyiidae but am trying to dip my toe in the water. I found these sunning on an ash tree in VC85(Fifeshire) last week and when potted the male took his chance to demonstrate that they were the same species (probably? Don't know how particular flies are!). I am struggling through the genus key (in part because I still struggle with Grimshaw's system for leg setae). I am hoping, though, that this may be sufficiently recognisable to allow me to work it back through the keys. The last image is of the female.

Cheers,
Ali

Re: Antho help please!

Have the eyes got short pale pubescence? And there is a strong lower katepisternal seta? Without better focussed shots of details it is very difficult to offer a definite determination.  Looking at the hypopygium I would say it is reminiscent of Lasiomma seminitidum. You have a specimen and I assume the Lasiomma key, so you can check if it seems to fit?

If you try taking a photograph of the eye margin with a dark background the short fine hairs may show up.

Re: Antho help please!

Many thanks, Michael

It certainly has pale eye hairs. Seems to have 4 ketepisternals. I'll run the keys through tomorrow and upload pics of those details such as they are. I remember being in the vicinity of Lasiomma in the genus key but then I'm sure I was in the vicinity of other genera too!

Cheers,
Ali

Re: Antho help please!

I have run this again through the keys based on my existing state of knowledge (I know all but nothing of the mid-tibia at this point). All questions I know the answer to go the right way in the keys and leave few couplets unexamined. I am more or less happy that this is L.seminitidum.

One comment on keys - I was somewhat disconcerted to have to describe the specimen as blackish (Lasiomma key couplet 1), especially since I have to say the opposite in genus key couplet 29.

On distribution I note that the species is said to have no records in Scotland. It's not unusual for me to find a common species in Scotland with only one known location (Dumbarnie Links, Fife), but this is because on many occasions common things aren't being recorded by anyone and only one other person has recorded them. The true distribution, especially in Fife, is seldom represented.

Many thanks once again


Here are pics of the eye, which is more evenly hairy than the lighting/focal depth may show, and the katepisternum

Re: Antho help please!

It is very gratifying that you were able to take more photos of the specific characters I suggested! It shows that if one is offered specific character photos then one can be sure of an identification. However hairy eyes does not work fo all Lasiomma (in spite of the generic name), as Lasiomma picipes has bare eyes! The genitalia show that it is however in the correct genus.

I suspect that the last posting is just an opportunist registerred user who has found a way of publishing their website to attrazct work.  If he lives in Boston NA Lasiomma seminitidum does not occur in the Nearctic Region, but I suppose it could be Boston Lincs?

Re: Antho help please!

I have deleted the links in the poster's profile and banned them so they cannot replace the link.
The location field is free text so there is probably no significance in the location 'Boston'. From the frequency of obscure UK locations in the spam posts I think the spambots select random locations from a gazetteer, relatively few claim to be from major centres of population.
If preferred I could delete the posting and also yours as it would not then have any context.
