Thread subject: Diptera.info :: Neoepitriptus inconstans from Marvão - PORTUGAL
#1
Antiphrisson trifarius (?) from Marvão (Edit: not Antiphrisson: Edit: neither Engelopogon)
Final August 2014
Neoepitriptus inconstans
#2
and the key... can someone confirm if is this trifarius?
#3
description... I only barely know German... can anybody help in this?

#4
I'm afraid it is not an Antphrisson species....because this creature has setae on the hind edges of the abdominal segments. Engel refers to Machimus aberrans as similar to Antiphrisson but with setae. A. trifarius in its normal form would have black setae in the lower part of the mystax.
Your fly has another strong character which
rules out M aberrans, it has setae on the underside of femur 1! This creature should be identifiable when we know the genus. It is puzzling me??????
Could you add pictures of the wings?
#7
Jorge, you can make better photos from the wings!
#8
I know, but i am in Lisbon and specimen and machine in Viseu

As i think now that it is an Engelepogon (Acanthopleura) species i would rather like to see a picture of the mesopleuron. It is not brunnipes because the first two segments of the antennae should be "yellow". From Spain also E. collarti and naxia are known according to Tolrá Anderson 2002

I will take photos tomorrow.
you mean... Acanthopleura Engel, 1927?? When was it synonymized?
#11
The genus was renamed by Lehr in 1992. (maybe has to do with the fact the name is in use for a genus of chitons in the family Chitonidae)
Your fly is Engelepogon collarti! Description by Bequaert fits very good. One distinguishing character are the bristles on the underside of the front femora.
#13
Forgot about this one : ( I was wrong. Engelepogon (Acanthopleura) should have strong bristles on the mesopleuron they are not there, or at least i can't see them. Wishful thinking on my side and my apologies for that. Please add a cf

Mystery solved:
Neoepitriptus inconstans
Type specimen from Portugal, but very common and widespread species over most of the Iberian Peninsula.
