Thread subject: Diptera.info :: Machimus gonatistes ♂ ???
#1
Hello
2 weeks ago i photographed this big robberfly (26-30mm) in northern Spain.
I think they looks like 'Machimus gonatistes', but I don't know which other machimus-species in Spain would be possible.
best regards
Markus

Hmmm, Spanish Machimus species are hard to identify (i haven't found a key yet that includes all endemic species) i would think the hypopygium does not fit M. gonatistes (http://www.robberflies.info/keyger/images/800/Asilinae/Machimus/gonatistes_m1_11_COGG.jpg). To me M. fimbriata is an option but that description doesn't fit entirely either. In short, i'm puzzled as usual

I would say
Machimus arthriticus.

Machimus arthriticus has bristles on the underside of femur 1 and has no projection or a tuft of hair on hind edge of eighth sternite. This one has no bristles on the underside of femur 1 and does have at least a tuft of hair on the edge of sternite eighth. Besides that M arthriticus has for a large part whitish bristles on back half (behind transverse suture) of scutum. It has also for a large part yellowish white bristles on legs. This one seems to have mainly black bristles. http://waarneming.nl/foto/view/5197450
So it is something else, with Engel the nearest i get is fimbriatus.

Point for you, it must had been too early for me though. Now I see those two significant features, which hadn't been clear for me earlier - the large size which doesn't fit my type at all and the lack of those unfortunate bristles. You're right that it must be something else but keep in mind it's still Spain huh...
