That works Martin.  I can open John's curation notes OK from the DF membership area.

The reddish hind tibiae combined with the overall appearance and abdominal pattern suggest Helina reversio to me.

The orange tips to the femora, and the very long anterodorsal and anterior bristles on the hind tibia, but particularly its stance and behaviour (= attitude!) add up to Coenosia tigrina

Thank you Tony ! 

Thank you Tony for your help ! I admire your knowledge about flies. It also makes me think about how much I have to learn ! 

It belongs to the muscidae family and not to the anthomyiidae family as I suggested first...

Although the colouration and pattern of the body is very similar, there are consistent structural differences between these two (and indeed between all Chlorops and Thaumatomyia). One of the easiest to see is the scutellum which is flat with closely-approximated apical bristles in Thaumatomyia, and convex with more widely positioned bristles in Chlorops. Do be wary of comparing on-line images of the two - it's highly likely that the photographers have misidentified their subjects. As a rule, DIptera.info has photos which are reliably named, as does Steven Falk's Flickr site, but I treat most everything else with suspicion.

This one is Elenchus tenuicornis - probably the commonest species caught by sweeping and malaise trapping. (The long bifid antennae are characteristic.) The hosts are delphacid hoppers. Other Strepsiptera are most often found as females, still embedded in the abdomens of their aculeate hosts, or as males attending these females. I believe the coleopterists take an interest in this group, but can't recall the latest ideas on the evolutionary relationships or higher systematics. 

That's tremendous, Tony.  Many thanks.  I never expected the speciment to be identified to species level. There are the strangest creatures.

Thank you Tony.  I am now sure I have T. notata.   It's good to learn what the differences are, however slight they may be.

Tony,

Here is my best picture yet of the scutum and scutelleum of this Chloropid?  It has one prominent terminal pair of bristles - closely approximated - with a much smaller pair of terminal bristles adjacent, and a very insignificant pair of terminal dorsocentrals.  I think this confirms the i/d as T. notata?

Alas, I failed to attach it!

Seems a very worthy first ID confirmation request on our new website.

WIth black legs and that thoracic pattern, it must be hilaris.

I suspect that the flattened hind femora indicate that the fly is recently emerged and the cuticle has not hardened sufficiently for the legs to retain their shape. We probably need better photos to say more.

Nigel Jones and I bought 12 drawer cabinets from Rescholar Equipment in India. They worked out relatively cheap compared to UK cabinets, even when shipping and import duties are taken into account. They are made of MDF and the door fit is not very tight so ideally needs a bit of additional sealing. However the drawers seal well. I have had mine for several years now and have had no problems with pests so far. I have no experience with the manufacturers youmention.

John.

P. pallida confirmed

Thanks Tony, I was hoping I had this one right. I will add it to IRecord. I also have several specimens of E. histrio to add.

Thanks Tony, I will try to improve my photography technique! I am pretty new to Diptera, although similar results occur in “teneral” Coleoptera.

I'm no expert on this family, but based on the online key via Diptera.info I would agree with you that this looks good for female S. punctatus.
