A rather striking Tipulidae with his black-and-white legs. Could someone please help me with an ID?

Suriname, Marowijne, East of Moiwana. VII-2013. In forest.

Thanks in advance,

After some more research, I now think this might be a Ptychopteridae, possibly a Bittacomorpha. Anyone to confirm this or offer another option?

Sigmatomera, family Tipulidae. (Suriname is in the New World, so Tipulidae.)

Thanks !

I now have an additional question though: I just checked the internet for a subfamily to put this genus in, but it appears to be placed in the family Limoniidae everywhere. So what do say? Tipulidae or Limoniidae?

Thanks again,

Scarabaeoid

The major catalog of world crane flies is from Europe. Europeans like to finely divide genera and families. The manuals of Nearctic and Central American Diptera follow the traditional single family classification of Alexander. Recent evidence suggests that family Limoniidae in the four family classification is not monophyletic.

I guess I'll best use both families then, divided by a slash so both followers of the European and the American classificastion are served.

Cheers,

That's definitely not Sigmatomera (Chioneinae) but Lecteria s.str. (Limnophilinae). It's very difficult to suggest a species from images only, though; using the key in Alexander, 1969m we can only exclude species with uniformly darkened tarsi (calopus, fuscitarsis, both Brazi; retrorsa, Colombia). Check also the recent paper by Ribeiro and Blagoderov (2009) on rediscovery of L. calopus in Brazil (Zoosymposia 3: 235-243).

The same correction of generic name applies to the creature from Colombia in Paul Bertner's post:
